After the oil well yield increasing measure sample database is established, the invention can update the oil well yield increasing measure sample database in real time, and the specific technical scheme is as follows.
Further, after the step S13, the oil well stimulation measure sample database is updated in real time according to the following scheme:
Establishing a data transmission channel between the oil well yield increase measure sample database and an oil field data system;
The well stimulation tool sample database is updated in real-time as data in the oilfield data system is updated.
Firstly, a data transmission channel is established between the oil well yield increase measure sample database and the oil field data system, the data transmission channel is established based on a WebSocket protocol, and the WebSocket allows a server to actively push data to a client.
Specific steps in the above step S11 are explained below.
Further, in the step S11, the layer segment information table is generated according to the following scheme.
Carrying out reforming sequencing treatment on each first measure time period in the pretreatment information table to obtain a corresponding second measure time period;
carrying out subdivision cutting treatment on each first production interval in the pretreatment information table to obtain a second production interval;
respectively carrying out two-dimensional association on each second measure time period and each second production layer period to generate a time layer period two-dimensional matrix data diagram;
Marking the production state of each second production interval and the matrix block corresponding to each second measure time interval in the time interval two-dimensional matrix data diagram;
And searching marks of a second production interval and a production state corresponding to each second measure time period in the time interval two-dimensional matrix data graph by taking the second measure time period as an index, and generating an interval information table according to a search result.
Firstly, carrying out rearrangement sequencing processing on each first measure time period in the pretreatment information table to obtain a corresponding second measure time period, wherein the first measure time period is a time period corresponding to a date field in the pretreatment information table, the second measure time period is a time period corresponding to the date field in the layer section information table, each first measure time period is divided according to perforation events, each first measure time period corresponds to a perforation event, after information recording is carried out by the perforation events, each first measure time period has an overlapped time period, and after the rearrangement sequencing processing is carried out on each first measure time period, the obtained corresponding second measure time period has no overlapped time period in time, so that the problem of unclear position switch is solved.
Then, carrying out subdivision cutting treatment on each first production interval in the pretreatment information table to obtain a second production interval, wherein the first production interval is an interval range corresponding to a perforation interval field in the pretreatment information table, the second production interval is an interval range after subdivision cutting, as shown in table 4, in the pretreatment information table, the first production interval is M1-M2, M4-M6, M3-M5 and M7-M8 respectively and is a perforation interval corresponding to four perforation events, but the perforation interval division of different measures has the problem of interleaving of the intervals, for example, the interleaving of the perforation intervals exists between M4-M6 and M3-M5; aiming at the problems, the subdivision cutting processing is carried out on each first production layer section in the pretreatment information table, and the subdivision cutting unit is a well section. For the M1-M2 interval range, it is equal to one subdivision cut unit, so that no subdivision cut is required; for the range of the M4-M6 well section, the unit of subdivision cutting is larger than that of the unit of subdivision cutting, so that subdivision cutting is divided into M4-M5 and M5-M6; similarly, for the range of the well section of M3-M5, the well section is subdivided and cut into M3-M4 and M4-M5; similarly, for the M7-M8 interval range, no subdivision of cuts is required. By the method, subdivision cutting processing of each first production interval in the pretreatment information table is completed, corresponding second production intervals are obtained, and the problem that well sections are staggered in perforation well section division of different measures is solved.
And then, respectively carrying out two-dimensional association on each second measure time period and each second production interval to generate a time interval two-dimensional matrix data diagram, wherein in the generated time interval two-dimensional matrix data diagram, the horizontal axis represents time, the vertical axis represents depth, the second measure time period corresponds, and different depths are different intervals.
Then, marking the production state of each second production layer segment and the corresponding matrix block of each second measure time segment in the time layer segment two-dimensional matrix data diagram, wherein in the time layer segment two-dimensional matrix data diagram, each second measure time segment of the horizontal axis is staggered with each second production layer segment of the vertical axis in a transverse and longitudinal direction, each matrix block is formed at each staggered position, each matrix block corresponds to a certain second production layer segment in a certain second measure time segment range, and the production state of the matrix block is marked, for example, different values are used for representing different production states, for example, if the production state is normal production, the production state is marked as 1; if the production state is production stopping, marking the production state as 0; if the production status is a transfer, the production status is marked as-1. By the mode, the production state of each second production interval in each second measure time period is supplemented, and the problem that the production state is not reflected or incomplete is solved.
And finally, taking each second measure time period as each record corresponding to the date field in the interval information table, taking the second measure time period as an index, searching the marks of the second production interval and the production state corresponding to each second measure time period in the time interval two-dimensional matrix data diagram, and generating the interval information table according to the search result. For example, the second measure time period used as an index is 201101-201403, the two-dimensional matrix data graph of the time period is searched according to the time period, the searched corresponding second production time periods are M1-M2, M4-M5 and M5-M6 respectively, the production states of the three searched second production time periods are all normal production, therefore, the searched data are added into the fields corresponding to the time period information table, the added second production time periods M1-M2, M4-M5 and M5-M6 are recorded in the time period information table as a production time period 1, a production time period 2 and a production time period 3 respectively, and the corresponding well marks and the belonging phases are added, so that the addition of one record in the time period information table is completed, the process is repeated, and a complete time period information table is generated after the addition of all records is completed.
Further, the rearrangement ordering processing is performed on each first measure time period in the pretreatment information table to obtain a corresponding second measure time period, which specifically comprises the following steps:
sequencing time nodes of each first measure time period in the pretreatment information table according to time sequence;
combining the time periods with overlapping time according to the time nodes after sequencing;
and deleting the invalid time node and reordering the valid time nodes to obtain each second measure time period formed by the reordered valid time nodes.
As shown in table 4, the date field of the pretreatment information table includes four records of first measure time periods, each first measure time period includes a start time node and an end time node, the first measure time periods are ordered according to time nodes of each first measure time period and the time sequence, for each first measure time period with overlapping time ranges, the first measure time periods are arranged from top to bottom, each first measure time period corresponds to one yield increase measure, and each ordered first measure time period is shown in fig. 3; then, according to the time nodes after sorting, the time periods with overlapping are combined, for the range from the time node ① to the time node ②, two overlapped first measure time periods are present, the two overlapped first measure time periods are combined, and similarly, the time periods with overlapping are respectively present in the ranges from the time node ② to the time node ③, the time node ③ to the time node ④ and the time node ④ to the time node ⑤, the time periods after the combination treatment are shown in fig. 3; next, after the merging process is completed, there are valid time nodes including time node ① to time node ②, time node ② to time node ③, and time node ④ to time node ⑤, and invalid time nodes including time node ③ to time node ④, so that the invalid time nodes are deleted and reordered to obtain each second measure time period formed by the reordered valid time nodes, the second measure periods include, as shown in fig. 3, a period of time node ① to time node ②, a period of time node ③ to time node ④, and a period of time node ⑤ to time node ⑥, each of which contains at least one stimulation measure after consolidation. In the above manner, the obtained second measure periods do not overlap in time, and each successive second measure period includes at least one perforation measure taken.
Further, the second measure time period and the second production interval are subjected to two-dimensional association to form a time interval two-dimensional matrix data graph, and the method specifically comprises the following steps of:
sequentially selecting a second measure time period in the interval information table;
