Description
Technical field
The invention belongs to rig simulation system field, particularly relate to the LED ring curtain projection display system that a kind of land rig installs operation simulation system.
Background technology
Along with the globalization of China Petroleum Technology and Development Corporation business, rig business various places all over the world, developing country has become company principal market.Along with outlet rig quantity increases, the accident occurred in rig use procedure also gets more and more, and gently then causes damage to equipment, affects manufacturing schedule, brings economic loss, heavy then lead to serious accident, causes casualties.The major accident several times particularly occurred in the resettlement of rig and use procedure abroad, causes harmful effect to the development of company and image.Rig belongs to engineering machinery, and the safety in production of engineering machinery not only directly affects the serviceable life of machinery, and is related to the safety of personnel and property.According to the investigation of Japanese labor science research institute, due to operator's error, the machine security accident that causes will account for 88% of total number of accident, and the accident that odjective cause causes only accounts for 9%, and all the other 2% are irresistible reason, and the culprit person of failing to understand only accounts for 1%.As can be seen here, 97% in engineering machinery security incident can take preventive measures.And percent in these accidents more than 90 are do not grasp correct using method due to operating personnel and operate lack of standardization causing.Country is due to the restriction of cultural difference and technical merit in Latin America, Africa and the Central Asia etc., and wellsite facility is installed, problem in unloading process is particularly outstanding.
After drilling well completes, to need wellsite facility, as base, derrick, steam piano, preventer stack etc. are dismantled, to be transported to other situ of drilling well, and to install, to start new drilling operation.In equipment installation and removal process, certain working specification and technical key point must be followed, the correct installation of guarantee equipment, correct dismounting and safe handling.
But the instructions that the working specification of current equipment user and technical key point are mainly provided by producer obtains with training, operative skill is then that these modes often exist following problem by the accumulation of experience and teaching of master worker:
Practice opportunity is limited, is difficult to improve technical level: due to the singularity of drilling operation, and some months is often wanted in the work such as the dismounting of drilling outfit and installation, even within 1 year, just carries out once, and operating personnel are difficult to accumulate various experience by practical operation.In addition, install at equipment, in unloading process, accident odds is relatively little, individual very limited to the process experience of accident, accumulation is difficult in the activity in production of reality to the judgement of accident, processing power and improves.Once burst accident, often from want of experience and processing power, cause the great loss of lives and property.
Traditional technical manual, operational manual content are scattered, consult inconvenience.The very difficult text description of operating process of some complexity is clear, in addition the individual difference understood, and causes maloperation and accident to occur most probably.How to improve equipment user level of skill, avoid the device damage because misoperation causes, minimizing accident occurs, and is the pressing problem that company must solve at present.
