Description

DESCRIPTION
REMOTE WELLS1TE SURFACE CONTROL SYSTEM AND METHOD BASED ON CLOUD SERVICE
TECHNICAL FIELD
The disclosure relates to the technical field of petroleum drilling engineering, in particular to a remote wellsite surface control system and method based on cloud service.
BACKGROUND
Directional drilling technology, which relates to a drilling method in which a wellbore reaches a formation of interest along a pre-designed well deviation angle and azimuth, is one of the most advanced drilling technologies in the field of petroleum exploration and development at present, which can effectively control the wellbore trajectory, so that a drill bit can drill to a preset subsurface target along a specific direction. The directional drilling C\I technology cannot operate without the "navigation path" of the logging-while-drilling system which is equivalent to a "thousand-mile eye" of a downhole equipment and can feed back downhole geological data along the drilling path to the surface at any time for optimizing o CO drilling operation and formation evaluation. The combination of the directional drilling technology and the logging-while-drilling technology can greatly improve the operation efficiency and reduce the engineering risk.
Logging-while-drilling is a complex project in which one of the important tools is the surface software system responsible for operation management at the well site and for obtaining sensor data from the surface and measurement data from downhole instruments. Engineers at the wellsite acquire construction information of the wellsite by using the surface software system to collect sensor data from the wellsite in real time. Meanwhile, pressure signals are decoded based on the mud pressure sensor data to obtain status indication information and formation measurement data information from the downhole tools, so as to acquire the operation status of the downhole tools and geological information collected by the downhole tools. The surface software system is further responsible for remotely transmitting data from the wellsite to a remote base service center where a remote expert analyze, process and explain the obtained data of the wellsite for guidance thereof, thereby achieving the purposes of greatly reducing the drilling cost and effectively improving the drilling benefit.
Operation of the existing surface software system is stand-alone, i.e., it runs independently. Engineers at the well site operate the surface software system on site to collect logging-while-drilling data. When it is required to transmit data to the outside, the system is connected to a server, to which the logging-while-drilling data and drilling-related data are remotely transmitted through international standard WITS or WITSML protocol. After processing and analyzing the data, the remote expert uses telephone and other methods to communicate with engineers at the well site.
The existing surface software system cannot solve the three problems as follows 1. Operation of the surface software system involves confidential technology relating to the instrument system due to the fact the system closely cooperates with the downhole hardware instruments, therefore a strict and detailed authority division function is required. In the prior art, a fixed user name and a respective password are used to log in, the account information is stored in a local computer, and the authentication system is also installed locally.
C\I When a user forgets the password, the local computer system malfunctions or is invaded by a Trojan horse' it may cause the account to be lost or stolen, which will affect the operation progress and endanger technical security. Therefore, conventional methods cannot meet the
CO
CD complex and safe authority requirements, and the remote base cannot control user login at the wellsite, resulting in a risk of technology leakage.
2. The surface software system has numerous software modules, and complex functions relating to a plurality of specialties such as drilling, logging and the like, and the system needs to be configured by professionals when running, so as to complete related functions. In the prior art, a specially-assigned person is required to perform the configuration on site, which is costly in time and capital and low in efficiency. When the on-site operator encounters problems in the configuration of the system, he/she uses a telephone to communicate with the remote administrator to solve the problems. Because the relevant information is huge and complicated, the remote administrator cannot obtain comprehensive and specific information about the on-site situations and the surface software system, with a result that the amount of information during communication is limited, therefore the efficiency is low.
3. The existing surface software system only supports remote transmission of logging and drilling related data, and cannot transmit related data such as software system operation logs.
Due to the complexity of the system, logging data are affected by on-site operations. However, as the remote expert cannot obtain a comprehensive understanding of on-site operation, it is difficult for them to obtain information such as software operation logs, and they cannot monitor whether the surface software processes the data correctly. What they can do is to analyze and process the logging data of the wellsite after being processed with the surface software system, which cannot troubleshoot the wrong data from the source, thus affecting the accuracy of remote data analysis.
In short, the prior art involves a method for transmitting limited data in a single direction. The existing system can only transmit logging-while-drilling data and drilling data to the outside, and does not involve the method of transmitting data related to the surface software system to the outside, nor the method of transmitting data from the outside to the inside. The existing system cannot control the login of on-site software, resulting in a high risk of technology leakage and inability to achieve flexible authority control. Because the surface software system is very complicated and has numerous software modules, its configuration and operation need to be maintained by professionals. In the prior art, the on-site software system C\I cannot be controlled remotely, and the expert need to operate on-site, which results in high o labor and time costs. In the prior art, when there is a problem in construction, remote staffs cannot obtain detailed operation records at the wellsite, and the wellsite operators can only
CO
communicate with the remote staffs by phone, which is prone to errors and has low efficiency.
SUMMARY
Aiming at the defects existed in the prior art, the present disclosure is intended to provide a remote wellsite surface control system and method based on cloud service, which can solve the defects existed in the prior art.
The technical solutions adopted by the present disclosure for achieving the above objective are described as follows.
There is provided a remote wellsite surface control system based on cloud service, including a configuration management cloud service module, an authentication and authorization cloud service system, a log management cloud service module, an instniction issuing cloud service module, a wellsite logging-while-drilling real-time data transmission system, a wellsite real-time video system, a surface software system and a remote decision-making system.
Authentication and authorization cloud service system: it is the core of the whole software system, and all modules that require login are connected to this system and supported with authority through the authentication and authorization cloud service system. Modules that require login through the authentication and authorization cloud service system mainly includes: the instruction issuing cloud service module, the configuration management cloud service module, the log management cloud service module, the well site real-time l oggingwhile-drilling data transmission system, the wellsite real-time video system, the surface software system and the remote decision-making system. By using the authentication and authorization cloud service system deployed in the cloud, a local machine can no longer save account information, thereby preventing on-site operation progress from being affected by forgotten passwords, system crashes, or Trojan horse intrusions. An administrator with authority is able to set user authority through remotely logging in to the authentication and authorization cloud service system, including user addition or deletion, user password modification, user role and authority settings.
The surface software system, once activated initially, needs to apply for authentication C\I from the cloud service; after the authentication is passed, the authentication and authorization o cloud service system provides the surface software system with authority mainly including: logging in to modules that are operable by the user in the surface software, modules that are
O CO
visible but inoperable by the user. After being authorized to login, the user is able to perform on-site operations on the surface software system.
Configuration management cloud service module: based on the authority function provided by the authentication and authorization cloud service system, a configuration administrator is able to remotely log in to the configuration management cloud service system in which the surface software system corresponding to a respective wellsite is selected and configured. After logging in, the surface software system applies for its configuration files to the configuration management cloud service; the surface software system is configured according to the obtained configuration files including: surface sensor configuration file, software system configuration file, display template configuration, logging instrument library configuration, default instrument parameter configuration, instrument function test configuration file, instrument calibration file configuration, unit system configuration file, and mud decoding algorithm configuration file.
Log management cloud service module: based on the authentication and authorization cloud service system, a relevant log administrator is able to log in remotely. The surface software system, when running, is connected to the log management cloud service module and uploads relevant logs generated by the system. The log administrator is able to collect and obtain information relating to the logs of the surface software system from each wellsite in real time, including: basic software system operation log, software operation log, module access log, and software error log. Each operation log of the surface system will be sent to a cloud platform database along with the logging data such that a remote expert is able to monitor the data processing of the surface software from the source.
Surface software system: it is used by the logging-while-drilling system for project construction management, instrument operation parameter configuration, instrument and wellsite information data acquisition, monitoring, processing and storage which are involved in the wellsite construction. The surface software system provides back-end service support based on cloud services of configuration management, authority management and log management, and a front-end interface is responsible for operations such as instrument C\I parameter configuration.
C\I Wellsite logging-while-drilling real-time data transmission system: it is responsible for real-time and remote transmission of data from the wellsite surface system to a remote cloud CO service integration system for use by the remote expert, and monitoring of data from the remote cloud service integration system. When the operating instruction is updated, the system transmits the latest instruction from the cloud to the surface software system.
Wellsite real-time video system: the wellsite real-time video system includes a camera installed on the derrick and a drone flying over the wellsite. The camera on the derrick is responsible for real-time recording of the construction video of the wellhead site, and the drone is responsible for recording the overall status of the wellsite. The videos recorded by the two are transmitted to the remote cloud service integration system in real time via the wellsite video system as data sources for a video monitoring module of the remote decision-making system.
Remote decision-making system: well site logging data streams, after being obtained by the system, are analyzed and processed by a geology-oriented software in combination with relevant geological, adjacent well and seismic data; and a next operation decision instruction is formed by the expert based on processing results from the system, and transmitted by the instruction issuing module to the remote cloud service integration system. When there is an abnormality in the wellsite, the expert can troubleshoot the problem through the video monitoring module. The system mainly includes real-time WITS/WITSML data processing and monitoring module, video monitoring module and decision instniction issuing module Remote cloud service integration system: the remote cloud service integration system is the integration and entrance of each cloud service and software and is responsible for the integration of authentication and authorization cloud service, configuration management cloud service, and log management cloud service. Program modules and services of the remote cloud are integrated into the remote cloud service integration system; the remote cloud service integration system is also the general login entrance for each service, and each service enters its respective function through the unified general entrance. In addition, the remote cloud service integration system is responsible for storage, management, processing of relevant data, and visualization function of wellsite data.
The disclosure further provides a remote well site surface control method based on cloud service, which specifically includes steps as follows.
C\I 1. According to relevant authority management regulations, an authority administrator assigns an account with a password having a different authority for each of a surface software
CD
system, a wellsite real-time video system, a remote decision-making system, a configuration
CO
CD management cloud service module and a log management cloud service module through an authentication and authorization cloud service system. A corresponding wellsite engineer, remote base expert, configuration administrator, log administrator can log in to a respective system to operate after obtaining the account information, 2. The configuration administrator logs in to the configuration management cloud service module, in which configuration files are generated according to well operation requirements and saved in the remote cloud service integration system, including: surface sensor configuration file, software system configuration file, display template configuration, logging instntment library configuration, default instalment parameter configuration, instrument function test configuration file, instrument calibration file configuration, unit system configuration file, and mud decoding algorithm configuration file.
3. The wellsite engineer logs in to the surface software system to obtain various configuration tables from the remote cloud service integration system by using an issuing module of the surface software system. A winch sensor, a pressure sensor, and a suspended load sensor are connected and configured using the surface sensor configuration file. System parameters in the surface software system are initialized using the software system configuration file, the display template configuration, the logging instrument library configuration, the unit system configuration file, and the mud decoding algorithm configuration file. The wellsite engineer uses a communication cable to connect the surface software system to a drilling tool to be placed downhole, and the drilling tool is initialized using the instrument parameter configuration, the instrument Function test configuration file, the instrument calibration file configuration. After the configuration is completed, the communication cable is removed to complete the system configuration and instrument configuration before the project.
4. The wellsite engineer installs a camera on the derrick to monitor operations on the drill floor, deploys a drone over the wellsite to monitor the overall situation of the wellsite, and connects, using cable or wireless routing, the drone to the wellsite real-time video system which is connected to the remote cloud service integration system using wireless routing and UDP communication protocol. The remote base expert obtains real-time video streams from the C\I remote cloud service integration system through a video monitoring module in the remote o decision-making system to monitor the real-time operating conditions on the drill floor and the wellsite.
CO
5. Before drilling, the wellsite engineer runs the surface software system to upload operation logs of each module of the system, including ordinary record logs, error logs, and warning logs, through a wellsite data transmission system to the remote cloud service integration system. The log administrator logs in to the log management cloud service to obtain operation logs of each module of the surface software system from the remote cloud service integration system in real time, and the log administrator uses the log management cloud service to generate a system operation report which is submitted to and viewed by the remote base expert. After confirming that the software is operating normally and the configuration is correct, the remote base expert informs the well site engineer that the drilling operation can be carried out.
6. During drilling operations, the surface software system obtains logging data based on the pressure data from the pressure sensor by using a built-in pressure decoding module, which are transmitted to the remote cloud service integration system through a network according to the WITS/WITSNIL protocol. Data streams from the remote cloud service integration system are obtained by the remote decision-making system in real time and restored to logging data after parsing. The remote base expert analyzes the logging data in combination with the geological data, and uses the instruction issuing cloud service to generate an operation instruction file recording parameters for adjusting a next wellbore trajectory, typically including parameters of well deviation angle and azimuth.
