[0034] S110. Determine the oil and gas reservoir evaluation index of each single well in the target area based on the single well test data.

[0035] In this solution, the single well test data may include oil test data, production test data, fluid property detection data, and test while drilling data, etc. The oil and gas reservoir evaluation index may include single well daily oil production, single well daily gas production, single well cumulative oil production within a preset time, single well cumulative gas production within a preset time, single well daily oil production capacity value, single well crude oil density, and single well gas measurement anomaly, etc. Based on the single well test data, the oil and gas reservoir evaluation index of each single well in the target area can be obtained.

[0036] S120. Determine the oil and gas reservoir evaluation index matching each depth interval according to the oil and gas reservoir evaluation index of each single well in the target area.

[0037] By counting the drilling depths of each single well in the target area, at least two depth intervals can be obtained. According to the oil and gas reservoir evaluation index of the single well in each depth interval, the oil and gas reservoir evaluation index matching each depth interval can be determined.

[0038] S130, determining the correlation between the oil and gas reservoir evaluation index matched with each depth interval and the oil and gas supply depth of each single well obtained in advance.

[0039] In this embodiment, before determining the correlation between the oil and gas reservoir evaluation index matched with each depth interval and the oil and gas supply depth of each single well obtained in advance, the method further includes:

[0040] The oil and gas supply depth of each single well in the target area is determined according to the completion data of the target area; wherein the completion data includes single well drilling completion data and oil well completion data.

[0041] According to the completion data, the oil and gas supply depth of each single well in the target area can be calculated. Specifically, according to the single well drilling and completion data, the lateral depth and vertical depth of each single well in the target layer can be determined. According to the oil well completion data, the lateral depth and vertical depth of the oil test layer section of each single well can be determined. According to the vertical depth of the target layer encountered by the single well and the vertical depth of the oil test layer section of the single well, the oil and gas supply depth of each single well can be calculated.

[0042] After obtaining the oil and gas supply depth of each single well, the oil and gas reservoir evaluation index matching each depth interval can be cross-analyzed with the oil and gas supply depth of each single well to obtain the correlation between the oil and gas reservoir evaluation index matching each depth interval and the oil and gas supply depth of each single well.

[0044] On the basis of the drilling depth of a single well whose oil and gas supply depth is to be determined in a known target area and at least one oil and gas reservoir evaluation index, the oil and gas supply depth of the single well can be determined according to the correlation between the oil and gas reservoir evaluation index matched in each depth interval and the oil and gas supply depth of each single well, thereby obtaining the reservoir-controlling bottom limit of strike-slip faults in the target area.

[0045] The technical solution of the embodiment of the present invention determines the reservoir evaluation index of each single well in the target area according to the single well test data; then determines the reservoir evaluation index matching each depth interval according to the reservoir evaluation index of each single well in the target area; then determines the correlation between the reservoir evaluation index matching each depth interval and the oil and gas supply depth of each single well obtained in advance; finally, determines the reservoir control bottom limit of strike-slip faults in the target area according to the correlation. This technical solution solves the problem of low reliability in determining the reservoir control bottom limit of strike-slip faults, and can provide corresponding technical support for the optimization of potential zones while improving the accuracy of predicting the reservoir control bottom limit of strike-slip faults.

[0046] Embodiment 2

[0047] Figure 2A This is a flow chart of a method for determining the bottom limit of strike-slip fault reservoir control provided in the second embodiment of the present invention. This embodiment is based on the above embodiment and is refined. Figure 2A As shown, the method includes:

[0048] S210. Determine the oil and gas reservoir evaluation index of each single well in the target area based on the single well test data.

[0049] This scheme takes area A as the target area and explains the process of determining the bottom limit of reservoir control by strike-slip faults.

[0050] Optionally, the single well test data includes oil test data; the oil and gas reservoir evaluation index includes single well daily oil production and single well daily gas production;

[0051] Determining the oil and gas reservoir evaluation index of each single well in the target area based on the single well test data includes:

[0052] Based on the oil test data, determine the daily oil production and gas production of a single well.

[0053] On the basis of the above scheme, optionally, the single well test data also includes test production data; the oil and gas reservoir evaluation index also includes the cumulative oil production of the single well within a preset time, the cumulative gas production of the single well within a preset time, and the daily oil production capacity value of the single well;

[0054] Determining the oil and gas reservoir evaluation index of each single well in the target area based on the single well test data includes:

[0055] Based on the test production data, determine the cumulative oil production of a single well within a preset time, the cumulative gas production of a single well within a preset time, and the daily oil production capacity of a single well.

[0056] The oil test data and production test data of a single well in area A can be shown in Table 1 below.

[0057] Table 1:

[0058]

[0059] According to the single well oil test data shown in Table 1, the daily oil production of the single well and the daily gas production of the single well can be determined. For example, the daily oil production of the single well is obtained according to the daily oil production, and the daily gas production of the single well is obtained according to the daily gas production. According to the test production data shown in Table 1, the cumulative oil production of the single well in the preset time and the cumulative gas production of the single well in the preset time can be obtained. The daily oil production capacity value of the single well can be calculated according to the cumulative oil production of the single well in the preset time.

[0060] Specifically, the calculation formula for the daily oil production capacity of a single well can be expressed as: Among them, q0 represents the daily oil production capacity of a single well, N p It indicates the cumulative oil production of a single well within a preset time, and t indicates the preset time, such as the number of production days of a single well.

[0061] In a feasible solution, the single well test data also includes test while drilling data; the oil and gas reservoir evaluation index also includes single well gas measurement abnormality;

[0062] Determining the oil and gas reservoir evaluation index of each single well in the target area based on the single well test data includes:

[0063] According to the test-while-drilling data, the abnormal gas logging volume of a single well is determined.

[0064] It is easy to understand that the test while drilling data may include gas logging anomaly data when the oil well encounters the target layer, such as the content of total hydrocarbons, C1, C2, C3, iC4, nC4, iC5, nC5, CO2 and H2S in each test layer. According to the test while drilling data, the gas logging anomaly of a single well can be obtained.

[0065] The test while drilling data of area A can be shown in Table 2, and the contents of CO2 and H2S in each single well test layer section are both 0. It can be understood that by comparing the gas content of each test layer section shown in Table 2 with the preset gas content threshold, the gas test abnormality of the single well can be determined.

[0066] Table 2:

[0067]

[0068] In another feasible solution, the single well test data also includes fluid property detection data; the oil and gas reservoir evaluation index also includes single well crude oil density;

[0069] Determining the oil and gas reservoir evaluation index of each single well in the target area based on the single well test data includes:

[0070] Determine the crude oil density of a single well based on the fluid property detection data.

[0071] It is understandable that the single well crude oil density can be the average crude oil density of the oil well at the initial stage of production. According to the fluid property detection data, the surface crude oil density of each production stage can be obtained, and according to the surface crude oil density of each production stage, the average crude oil density of the oil well at the initial stage of production can be obtained.

[0072] S220. Determine the single wells that match each depth interval according to the drilling depth of each single well.

[0073] By counting the drilling depths of each single well, the single well corresponding to each depth interval can be obtained.

[0074] S230, taking each depth interval as a target depth interval in turn, and calculating the oil and gas reservoir evaluation index matching the target depth interval according to the oil and gas reservoir evaluation index of the single well matching the target depth interval and the drilling depth of the single well.

[0075] After determining the single wells in each depth interval, the single well oil and gas reservoir evaluation index in each depth interval can be depth-weighted according to the drilling depth of the single well. The specific calculation method of the oil and gas reservoir evaluation index matching the target depth interval can be as follows:

[0076] Among them, A represents the oil and gas reservoir evaluation index matching the target depth interval, A1, A2…A n Represents the oil and gas reservoir evaluation indicators of each single well in the target depth range, D1, D2…D n Indicates the drilling depth of each single well.

[0077] Figure 2B is a schematic diagram of the intersection analysis between the total hydrocarbon content of each single well in the depth interval X and the oil and gas supply depth according to the second embodiment of the present invention, Figure 2C 1 is a schematic diagram of the intersection analysis of the total hydrocarbon content and the oil and gas supply depth of the depth interval X provided by the second embodiment of the present invention. Taking the correlation between the oil and gas supply depth and the total hydrocarbon content of the depth interval X as an example, the total hydrocarbon content of each single well in the depth interval X and the oil and gas supply depth are directly analyzed to obtain the following: Figure 2B The scatter plot shown is based on Figure 2B The scattered distribution shown in the figure is difficult to fit the correlation between total hydrocarbon content and oil and gas supply depth. After depth-weighted averaging of the total hydrocarbon content of a single well in depth interval X, the intersection analysis of the total hydrocarbon content matching depth interval X and oil and gas supply depth can be obtained. Figure 2C Therefore, this scheme is conducive to accurately and reliably locating the correlation between oil and gas reservoir evaluation indicators and oil and gas supply depth, thereby ensuring the feasibility of predicting the bottom limit of strike-slip fault control.

[0078] S240: Determine the correlation between the oil and gas reservoir evaluation index matched with each depth interval and the oil and gas supply depth of each single well obtained in advance.

[0079] In this solution, optionally, the determination of the correlation between the oil and gas reservoir evaluation index matched with each depth interval and the oil and gas supply depth of each single well obtained in advance includes:

[0080] If the number of reservoir evaluation indicators matching the target depth interval is greater than 1, the reservoir evaluation indicators matching the oil and gas supply depth with the target depth interval are sequentially analyzed to obtain the correlation between the reservoir evaluation indicators matching the oil and gas supply depth with the target depth interval.

[0081] The number of reservoir evaluation indicators that match the target depth interval can be one or more. If the number of reservoir evaluation indicators that match the target depth interval is more than one, the oil and gas supply depth and each reservoir evaluation indicator that matches the target depth interval are sequentially analyzed, and a correlation chart of the oil and gas supply depth and each reservoir evaluation indicator is drawn to obtain the correlation between the oil and gas supply depth and the reservoir evaluation indicator that matches the target depth interval.

[0082] S250. Determine the reservoir-controlling bottom limit of the strike-slip fault in the target area based on the correlation relationship.

[0083] The technical solution of the embodiment of the present invention determines the reservoir evaluation index of each single well in the target area according to the single well test data; then determines the reservoir evaluation index matching each depth interval according to the reservoir evaluation index of each single well in the target area; then determines the correlation between the reservoir evaluation index matching each depth interval and the oil and gas supply depth of each single well obtained in advance; finally, determines the reservoir control bottom limit of strike-slip faults in the target area according to the correlation.
