Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

In order to better predict the effect of the production increase measures and ensure that the measure effect prediction model is accurate and reliable, an embodiment of the present invention provides a method for establishing a sample database of oil well production increase measures. As shown in FIG. 1 , the method includes the following steps:

S11, generating a layer section information table corresponding to each oil well according to the pre-processing information table of each oil well;

S12, constructing a text file of historical data according to the layer information table corresponding to each oil well and the multi-source data table;

S13. Establishing a sample database of oil well production increase measures based on the text file and the measures data table.

The method for establishing a sample database of oil well production increase measures provided by an embodiment of the present invention firstly aims at the problem of inconsistent data formats for the same data information in different blocks or different wells in the same block in an oil field, and establishes a unified data format specification standard for data information such as well deviation data, logging data, small layer data, monthly production data, and comprehensive data, so as to facilitate the query, retrieval and use of data information; secondly, in order to clarify the layer switch, divide the layer section in detail, and supplement the production status, thereby building a spatiotemporal two-dimensional framework for the interconnection of multi-source and multi-type data, this solution generates a layer section information table corresponding to each oil well according to the preprocessing information table of each oil well, and the layer section information table is shown in Table 1 As shown, then according to the corresponding layer information table generated by each oil well, combined with the multi-source data table storing multiple types of data, a text file of historical data is constructed. The text file of historical data is referred to as His (History) text file in the following text. The format of His text file is shown in Figure 2, realizing the interconnection between multi-source and multi-type data; then according to the constructed His text file, combined with each record in the measure data table and the data in the monthly production data table, the monthly production data table contains parameters as shown in Table 2, and finally a sample database of oil well production increase measures is established. The sample database of oil well production increase measures contains parameters as shown in Table 3. In this embodiment, the perforation event is taken as an example of the production increase measure, and the preprocessing information table is established with the perforation event as the index, and the preprocessing information table is shown in Table 4.

After the oil well production increase measure sample database is established, the present invention can update the oil well production increase measure sample database in real time. The specific technical scheme is as follows.

Furthermore, after the above step S13, the real-time update of the oil well production increase measure sample database is achieved through the following scheme:

Establishing a data transmission channel between the oil well production enhancement measure sample database and the oilfield data system;

When the data in the oilfield data system is updated, the oil well production increase measure sample database is updated in real time.

First, a data transmission channel is established between the oil well production increase measures sample database and the oilfield data system. The data transmission channel is established based on the WebSocket protocol. WebSocket allows the server to actively push data to the client. In this solution, the oilfield data system serves as the server and the oil well production increase measures sample database serves as the client. When the data in the oilfield data system changes within a period of time, the changed data can be actively pushed to the oil well production increase measures sample database, thereby realizing real-time data acquisition and real-time updating of the oil well production increase measures sample database, which is convenient for data statistics and updating.

The specific steps in the above step S11 are described below.

Furthermore, in the above step S11, the generation of the layer segment information table is achieved through the following scheme.

Rearrange and sort each first measure time period in the pre-processing information table to obtain a corresponding second measure time period;

Subdividing and cutting each first production layer segment in the pre-processing information table to obtain a second production layer segment;

Two-dimensionally associate each of the second measure time periods with each of the second production layer sections to generate a two-dimensional matrix data diagram of the time layer section;

Marking the production status of the matrix blocks corresponding to each second production layer segment and each second measure time period in the two-dimensional matrix data diagram of the time layer segment;

Using the second measure time period as an index, the second production layer segment and the production status mark corresponding to each second measure time period in the time layer segment two-dimensional matrix data diagram are retrieved, and a layer segment information table is generated according to the retrieval result.

First, each first measure time period in the preprocessing information table is reorganized and sorted to obtain the corresponding second measure time period. The first measure time period is the time period corresponding to the date field in the preprocessing information table, and the second measure time period is the time period corresponding to the date field in the layer information table. Each first measure time period is divided according to the perforation event. Each first measure time period corresponds to a perforation event. After the perforation event is used to record information, there are overlapping time periods in each first measure time period. After the first measure time periods are reorganized and sorted, the corresponding second measure time periods obtained do not have overlapping time periods in time, which solves the problem of unclear layer switches.

Then, each first production layer segment in the preprocessing information table is subdivided and cut to obtain the second production layer segment. The first production layer segment is the layer segment range corresponding to the perforation well segment field in the preprocessing information table, and the second production layer segment is the layer segment range after subdivision and cutting, as shown in Table 4. In the preprocessing information table, the first production layer segments are M1-M2, M4-M6, M3-M5, and M7-M8, which are the perforation well segments corresponding to four perforation events, respectively. However, the perforation well segment division of different measures has the problem of well segment interleaving, for example, there is well segment interleaving between M4-M6 and M3-M5. In view of the above problems, each first production layer segment in the preprocessing information table is subdivided and cut, and the unit of subdivision and cutting is a well segment. For the M1-M2 well section range, it is equal to a subdivided cutting unit, so no further subdividing and cutting is required; for the M4-M6 well section range, it is greater than a subdivided cutting unit, so the subdividing and cutting is M4-M5, M5-M6; similarly, for the M3-M5 well section range, the subdividing and cutting is M3-M4, M4-M5; similarly, for the M7-M8 well section range, no further subdividing and cutting is required. Through the above method, the subdividing and cutting processing of each first production layer section in the pre-processing information table is completed, and the corresponding second production layer section is obtained, which solves the problem of interlacing of well sections in the perforation well section division of different measures.

Next, each of the second measure time periods is two-dimensionally associated with each of the second production layer segments to generate a two-dimensional matrix data diagram of the time segment. In the generated two-dimensional matrix data diagram of the time segment, the horizontal axis represents time, corresponding to the second measure time period, and the vertical axis represents depth, corresponding to the second production layer segment. Different depths correspond to different layers.

Then, the production status of each second production layer segment and each matrix block corresponding to the second measure time period in the two-dimensional matrix data diagram of the time layer segment is marked. In the two-dimensional matrix data diagram of the time layer segment, each second measure time period on the horizontal axis is staggered with each second production layer segment on the vertical axis, and each matrix block is formed at each staggered position. Each matrix block corresponds to a second production layer segment within a second measure time period. The production status of the matrix block is marked, such as using different values to represent different production statuses. For example, if the production status is normal production, the production status is marked as 1; if the production status is shutdown, the production status is marked as 0; if the production status is transfer, the production status is marked as -1. In the above manner, the production status of each second production layer segment in each second measure time period is supplemented, solving the problem that the production status is not reflected or is incomplete.

Finally, each second measure time period is used as each record corresponding to the date field in the layer segment information table, and the second measure time period is used as an index to retrieve the second production layer segment and the production status mark corresponding to each second measure time period in the time layer segment two-dimensional matrix data map, and generate the layer segment information table according to the retrieval result. For example, the second measure time period used as the index is 201101-201403, and the time layer segment two-dimensional matrix data map is retrieved according to this time period. The corresponding second production layer segments retrieved are M1-M2, M4-M5, and M5-M6, and the production status of the three retrieved second production layer segments are all normal production. Therefore, the retrieved data is added to the corresponding field of the layer segment information table, and the added second production layer segments M1-M2, M4-M5, and M5-M6 are recorded as production layer segment 1, production layer segment 2, and production layer segment 3 in the layer segment information table, and the corresponding well number and the stage to which they belong are added, thereby completing the addition of a record in the layer segment information table, repeating the above process, and generating a complete layer segment information table after completing the addition of all records.

Further, each first measure time period in the pre-processing information table is re-arranged and sorted to obtain a corresponding second measure time period, which specifically includes the following steps:

Sorting the time nodes of each first measure time period in the pre-processing information table in chronological order;

According to the sorted time nodes, the overlapping time periods are merged;

Invalid time nodes are deleted and valid time nodes are reordered to obtain second measure time periods formed by the reordered valid time nodes.

As shown in Table 4, the date field of the preprocessing information table contains four records of the first measure time period, each of which contains a start time node and an end time node. According to the time nodes of each first measure time period, they are sorted in chronological order. For the first measure time periods with overlapping time ranges, they are arranged from top to bottom. Each first measure time period corresponds to a production increase measure. Each first measure time period after sorting is shown in Figure 3. Then, according to the sorted time nodes, the overlapping time periods are merged. For the range from time node ① to time node ②, there are two overlapping first measure time periods. The two overlapping first measure time periods are merged. Similarly, the first measure time periods from time node ② to time node ③, from time node ③ to time node ④, and from time node ④ to time node ⑤ are merged. The overlapping time periods within the range of time node ④ to time node ⑤ are merged, and each time period after the merging process is shown in Figure 3; next, after the merging process is completed, there are valid time nodes and invalid time nodes, and the valid time nodes include time node ① to time node ②, time node ② to time node ③ and time node ④ to time node ⑤, and the invalid time nodes include time node ③ to time node ④, so the invalid time nodes are deleted, and the valid time nodes are re-sorted to obtain each second measure time period formed by the valid time nodes after re-sorting. The second measure time period includes the time period from time node ① to time node ②, the time period from time node ③ to time node ④, and the time period from time node ⑤ to time node ⑥ as shown in Figure 3, and each second measure time period contains at least one production increase measure after the merger. In the above manner, each second measure time period obtained does not overlap in time, and each continuous second measure time period contains at least one perforation measure taken.

Furthermore, the second measure time period is two-dimensionally associated with the second production layer segment to form a two-dimensional matrix data diagram of the time segment, which specifically includes the following steps:

Select the second measure time period in the layer section information table in sequence;

According to the selected second measure time period, traverse the first measure time period in the pre-processing information table to determine the subordinate relationship between the second measure time period and the first measure time period;

Determining, according to the affiliation, a second production layer section corresponding to the second measure time period;

The second measure time period is two-dimensionally associated with the corresponding second production layer segment to form a two-dimensional matrix data diagram of the time layer segment.

As shown in Table 1, the date field of the layer segment information table contains three second measure time periods. The second measure time periods in the layer segment information table are selected in turn, and then the first measure time periods in the preprocessing information table are traversed according to the selected second measure time periods to determine the affiliation between the selected second measure time period and the first measure time period. For example, the first second measure time period 201101-201403 in the layer segment information table is first selected, and then the first measure time period in the preprocessing information table is traversed to determine that the selected second measure time period 201101-201403 is affiliated to the first first measure time period 201101-201905 and the second first measure time period 201101-201905 in the preprocessing information table. Then, according to the above affiliation, the second production layer segment corresponding to the selected second measure time period is determined, because the selected second measure time period 201101-201403 Belonging to the two first measure time periods of 201101-201905 and 201101-201905, the first production layer segment corresponding to the first first measure time period 201101-201905 is M1-M2, the first production layer segment corresponding to the second first measure time period 201101-201905 is M4-M6, the second production layer segment corresponding to the first production layer segment M1-M2 is M1-M2, and the second production layer segment corresponding to the first production layer segment M4-M6 is M4-M5 and M5-M6. Therefore, the second production layer segments corresponding to the selected second measure time period 201101-201403 are M1-M2, M4-M5 and M5-M6; finally, the second measure time period is two-dimensionally associated with the corresponding second production layer segment, the horizontal axis is time, corresponding to the second measure time period, and the vertical axis is depth, corresponding to the second production layer segment, and finally a two-dimensional matrix data diagram of time segment is formed as shown in Figure 4.

In the above scheme, according to the layer information table and multi-source data table corresponding to each oil well, a His text file is constructed, which is implemented in the following way:

The information in the layer information table corresponding to each oil well, as well as the monthly production data table, the small layer data table, and the logging data table are integrated and stored to construct a His text file.

First, the date in the layer information table corresponding to each oil well is used as the index to obtain the monthly production, stage production, cumulative production and other information in the monthly production data table; then, the layer sounding in the layer information table corresponding to each oil well is used as the index to obtain the production status of each stage and the production layer sequence number in the layer information table; the interpretation sequence number, layer position and other information in the small layer data table are obtained, and the geological information such as permeability in the well logging data table is obtained, and the obtained information of each well is stored in the His text file to realize the interconnection of multi-source and multi-type data.

Furthermore, according to the His text file and the measure data table, a sample database of oil well production increase measures is established, which specifically includes the following steps:

Using each record in the measure data table as an index, extract the corresponding parameter information in the His text file and the monthly production data table within the validity period of the measure. If vertical depth related parameters are involved, call the well inclination data to perform depth measurement and vertical depth conversion;

According to the measure data table and monthly production data table, generate the production curve of the entire well history of each well, the production curve of the effective period of the measure sample and the corresponding measure label information, and generate the corresponding picture information;

The parameter information and the image information are added to each measure record in the measure data table to establish a sample database of oil well production increase measures.

First, take each record in the measure data table as an index, and extract the corresponding information in the His text file and the monthly production data table within the validity period of each measure in each well. In the process of data information extraction, if vertical depth related parameters are involved, the well inclination data is called to perform depth measurement and vertical depth conversion. The main information extracted from the His text file includes: determining the production stage where the completion date is located; obtaining the corresponding sub-layer sequence number; querying the corresponding sub-layer geological property information; converting vertical depth from depth measurement, and calculating the corresponding layer section and average physical properties. The information extracted from the monthly production data table is shown in Table 2. Each record in the measure data table as an index may include well number, measure category, completion date, expiration date, etc. The above-mentioned extraction of information within the validity period of each measure in each well can be interpreted as extracting only information within the validity period of each measure, such as extracting production information. The production information includes production data of all months. If all production information is extracted, it is impossible to intuitively understand the effect of taking measures. Therefore, only the production information of the months within the validity period of each measure is extracted to intuitively understand the effect of measures after taking measures.

Then, according to the data information in the measure data table and the monthly production data table, the production curve of the entire well history of each well is generated as shown in Figure 5, and the production curve of the effective period of the measure sample is generated as shown in Figure 6, and the corresponding measure label information is indicated in the above production curves to realize automatic visualization of the production curve of the entire well history of each well and the effective period of the measure sample, automatic measure label recognition, and generate corresponding image information.

Finally, the extracted parameter information and the picture information are added to each measure record in the measure data table. The picture information can be added in the form of a hyperlink, and finally the establishment of the oil well production increase measure sample database is completed.

The embodiment of the present invention also provides a method for establishing a visualized plate map of a block oil well, as shown in FIG. 7 , comprising the following steps:

S51, generating a visualized time-layer two-dimensional matrix data graph of each oil well according to the layer information table corresponding to each oil well;

S52. Based on the visualized two-dimensional matrix data diagram of the time segment corresponding to each oil well, a visualization framework of the block oil wells is established and the oil well information is associated to establish a visualization plate map of the block oil wells.

Furthermore, the above step S52 is specifically implemented in the following manner:

According to the geographic coordinates of each oil well, in the preset map data, the visualized time layer two-dimensional matrix data diagram corresponding to each oil well is associated with the geographic coordinates and displayed through the block oil well visualization plate map.
