[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below in combination with specific implementation methods. It should be understood that the embodiments of the present disclosure and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations on the technical solution of the present invention. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

[0042] Figure 1 FIG. 1 is a flow chart of a method for drawing a production-intake profile comparison diagram of an oil well provided by an embodiment of the present invention. Figure 1 As shown, the method for drawing a comparative diagram of oil well production and absorption profiles includes the following steps:

[0043] S1. Based on a user's data acquisition request, a database is linked and production and absorption profile data of a specified test date is acquired through the database. The production and absorption profile data includes the number of tests, test time, layer name, layer depth, layer thickness, production and absorption parameters, and measures taken;

[0044] In an embodiment of the present invention, the database is the A2 database in the oil, gas and water well production data management system. The embodiment of the present invention responds to the user's data acquisition request and obtains the corresponding production and absorption profile data from the corresponding database according to the data acquisition request; wherein, the number of tests can be the number of times the current production and absorption profile data is tested and the number of tests, and the test time can be the time used for the test, and can also include the time during the test, etc.

[0045] Specifically, the embodiment of the present invention needs to verify the user's identity information and corresponding access rights before feeding back the production and absorption profile data. The embodiment of the present invention links to the database based on the user's data acquisition request, and obtains the production and absorption profile data of the specified test date through the database, including linking to the database based on the user's data acquisition request, verifying the user's access rights and confirming the user's authority level; wherein, if the user's authority level meets the acquisition conditions of the production and absorption profile data, the data acquisition request is parsed and the production and absorption profile data of the specified test date is obtained from the database; if the user's authority level does not meet the acquisition conditions of the production and absorption profile data, the data acquisition request is parsed and basic data that meets the user's authority level is obtained from the database, the basic data being the simplified production and absorption profile data of the specified test date, which is only used for preview and does not contain core data to avoid leakage, thereby improving security.

[0046] At the same time, in order to ensure the availability of the acquired production and absorption profile data, an embodiment of the present invention verifies the production and absorption profile data based on data cleaning technology to confirm whether the production and absorption profile data meets the availability conditions. The availability conditions include a first condition, a second condition, and a third condition. The first condition is that the production and absorption profile data meets the requirement of correctness, the second condition is that the production and absorption profile data meets the requirement of no duplication, and the third condition is that the production and absorption profile data meets the requirement of completeness. That is, for the availability of the production and absorption profile data, it is necessary to ensure that the production and absorption profile data is correct (correctness), no duplication (singleness), and no missing (completeness). When the verification result is that the production and absorption profile data does not meet at least one of the first condition, the second condition, and the third condition, the embodiment of the present invention generates and returns a problem report. The problem report is used to send to data maintenance personnel and users to facilitate rapid confirmation of the problem and execution of subsequent production adjustments.

[0047] Among them, confirming that the production and absorption profile data meets the requirements for correctness means complying with natural and production laws, for example, the sum of the production and absorption parameters of all layers in a test is 1, the layers cannot overlap, the layer depth is less than the well depth, etc.; in some embodiments of the present invention, when the verification result is that the production and absorption profile data does not meet the first condition and / or the third condition, the embodiment of the present invention can select the historical production and absorption profile data corresponding to the most recent test time of the production and absorption profile data as a replacement. If the verification result is that the production and absorption profile data does not meet the second condition, the duplicate production and absorption profile data can be deleted and a problem report can be generated.

[0048] S2. generating a production-absorption profile diagram according to the production-absorption profile data based on a map analysis technology;

[0049] In an embodiment of the present invention, the production and absorption profile is a two-dimensional distribution diagram based on the production and absorption profile data, wherein the vertical axis represents the stratum test results of a single well, including stratum depth, stratum thickness, etc., such as being displayed proportionally to the sandstone thickness of each stratum, with shallow layers at the top and deep layers at the bottom; the horizontal axis represents the test time of the single well, such as being based on the chronological order of the test, with the date indicated below the graph. For other parameter data, for example, the stratum test results can be displayed as a rectangle and marked with a lithologic identifier, with the height in the production and absorption profile being proportional to the stratum thickness and the position in the production and absorption profile being proportional to the stratum depth; the production and absorption parameters can be displayed as a rectangle, with the height consistent with the rectangle of the stratum data and the length proportional to the production and absorption parameter value.

[0050] Specifically, the map parsing technology described in the embodiment of the present invention generates a production-absorption profile according to the production-absorption profile data, including identifying invalid well section information in the production-absorption profile and compressing the invalid sections.

[0051] Since the non-reservoir segment does not store oil but still exists in the production and absorption profile, it will increase the difficulty of the user in reading the map and even mislead the user. Therefore, it is necessary to identify and process the invalid segments composed of these non-reservoir segments in the production and absorption profile. Specifically, an embodiment of the present invention trains a convolutional neural network based on historical data, and the historical data is the historical production and absorption profile data used or specified by the user. By inputting the historical production and absorption profile data into the convolutional neural network for training, the invalid segments in the production and absorption profile can be quickly and accurately identified; the embodiment of the present invention performs image recognition processing on the production and absorption profile through an image recognition algorithm, including scaling and normalization processing, and converts it into a processing format corresponding to the convolutional neural network. The converted production and absorption profile is input into the convolutional neural network for processing, and the invalid segments in the production and absorption profile are identified, the invalid segments are merged into a blank area, and the segment length is marked.

[0052] S3. Acquire all the production and absorption profiles generated by the user, and splice all the production and absorption profiles into a production and absorption profile comparison diagram according to a preset diagram template.

[0053] The production-absorption profiles are generated according to the production-absorption profile data corresponding to the user's designated test date, and the production-absorption profiles generated corresponding to all the user's designated test dates are obtained. In the embodiment of the present invention, the generated production-absorption profiles are sorted based on the order of the designated test dates, and the sorted production-absorption profiles are sequentially spliced ​​according to the preset drawing template to obtain a production-absorption profile comparison diagram. Figure 2As shown, it is a reference schematic diagram of the liquid production profile comparison diagram of a certain embodiment of the present invention. In the figure, the horizontal axis is the test time, the vertical axis is the layer name, the red area indicates the lithology information, and the blue area is the liquid production ratio (%) of the layer each time tested. The color of the area is only used for distinction. According to actual application requirements, other colors can also be selected in other implementation methods, as long as the distinction effect is achieved.

[0054] The method for drawing a comparative diagram of oil well production and absorption profiles according to the embodiment of the present invention has the following advantages over the prior art:

[0055] 1. Directly obtain the production and absorption profile data of the specified test date from the database according to the user's data acquisition request, which optimizes the complicated screening process, improves the data acquisition efficiency, and speeds up the mapping efficiency;

[0056] 2. By verifying the user's identity information and feeding back corresponding data based on the user's permission level, data security is improved;

[0057] 3. Verify the availability of the acquired production and absorption profile data, including its correctness, uniqueness, and completeness, to ensure the authenticity and reliability of the data;

[0058] 4. Through big data training, invalid well section information in the production and absorption profile is identified and blanked out. The remaining valid information after filtering is compressed and spliced ​​into a production and absorption profile comparison map according to the well section height ratio. This facilitates users to quickly compare results, reduces the difficulty of reading the map, and improves the reading efficiency and user experience.

[0059] 5. By comparing the changing trends on the time axis, the water injection volume of each oil layer in the water injection well, the pressure and liquid production of each oil layer in the oil production well can be quickly determined, and the process measures such as stratified oil production, stratified water injection, stratified fracturing, and stratified water plugging can be guided. It has reference value for the subsequent alleviation of inter-layer conflicts and the improvement of the efficiency of controlling the water content rising rate.
