However, this method has problems such as the subjectivity of the value selection process of the development probability of oil and gas accumulation parameter factors and the unintuitive plane comparison of the geological success rates of different exploration targets within the block, which is not conducive to project managers to understand the technical process and results of the scheme, and to make horizontal comparisons of the evaluation results.

[0049] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0050] This embodiment 1:

[0051] This example takes the geological success rate evaluation of three oil and gas exploration targets in Block X as an example. In this example, there are three wells within the mining rights of Block X, and the three-dimensional seismic data are fully covered. These wells and seismic data are the data sources of the parameter factors of the reservoir geological conditions. In addition, there are 12 wells outside Block X and within the same structural geological unit. They are the data sources for regional statistics on the relationship between parameter factors and the development of oil and gas reservoir conditions ( Figure 2 ).

[0052] A graphical comparison method for the geological success rate of oil and gas exploration targets, such as Figure 1 As shown, including:

[0053] S101, reading the drilling geological information and the parameter factors of the oil and gas accumulation conditions of the corresponding seismic data geological interpretation results to compile a plane diagram of the parameter factors of the oil and gas accumulation conditions;

[0054] The oil and gas accumulation conditions involved in the evaluation of the geological success rate of oil and gas exploration targets include hydrocarbon source, reservoir, cap rock, and transportation conditions.

[0055] The oil and gas accumulation conditions that need to be read from the drilling geological information and the geological interpretation results of seismic data include source, reservoir and cap rock conditions. The parameter factor of the source condition is the vitrinite reflectivity of the source rock, the parameter factor of the reservoir condition is the sedimentary phase of the stratum to which the reservoir belongs, and the parameter factor of the cap rock condition is the thickness of the stratum to which the cap rock belongs. The oil and gas accumulation conditions that only need to be read from the geological interpretation results of seismic data are the transport conditions, and the parameter factor is the distribution of oil source faults.

[0056] In some embodiments, the specific construction process of compiling the oil and gas accumulation condition parameter factor plane map is as follows:

[0057] Input the oil and gas reservoir condition parameter factors corresponding to the drilling geological information related to regional drilling in the form of data points, and obtain the data range for the drilling within the mining rights of the block to which the target to be evaluated belongs;

[0058] The oil and gas reservoir condition parameter factors corresponding to the geological interpretation results of the seismic data corresponding to the oil and gas exploration target are input in the form of a data grid, and the interpretation results within the mining rights of the block to which the target to be evaluated belongs are obtained, thereby forming a plane diagram of the oil and gas reservoir condition parameter factors.

[0059] Specifically, the source rock vitrinite reflectance, reservoir sedimentary phase, and caprock thickness information of wells A, B, and C are input in the form of data points, and the source rock vitrinite reflectance, reservoir sedimentary phase, caprock thickness, and oil source fault interpretation results based on the three-dimensional seismic data of Block X are input in the form of data grids. After the well point data and seismic grid data are superimposed, interpolation is performed based on the minimum curvature method, and a parameter factor plane diagram of each oil and gas accumulation condition is compiled with Block X as the scope, such as Figure 3 shown.

[0060] S102, referring to the regional statistical results of the relationship between the parameter factors and the development of oil and gas accumulation conditions, establishing a scoring basis for the probability of the development of the accumulation conditions;

[0061] Specifically, the specific method for establishing the scoring basis for the probability of reservoir formation conditions is as follows:

[0062] The probability of the development of the hydrocarbon source conditions is scored based on the regional statistical results of the hydrocarbon supply capacity corresponding to the vitrinite reflectance of the source rock;

[0063] The probability of development of the reservoir conditions is scored according to the regional statistical results of rock reservoir effectiveness corresponding to each type of deposition;

[0064] The development probability of the cap rock condition is scored according to the regional statistical results of oil and gas plugging effectiveness corresponding to the cap rock thickness;

[0065] The probability of development of the transport conditions is scored according to the regional statistical results of the relationship between the distance from the oil source fault and the effectiveness of fault transport.

[0066] In this embodiment, the above geological information of 12 wells in the structural geological unit and outside the X block is statistically analyzed, and the distribution and trend fitting relationship of the data points of hydrocarbon source, cap rock and transport condition are shown as follows: Figure 4 The statistical results of reservoir conditions are shown in Table 1:

[0068] Sedimentary phase Reservoir development well Reservoir is not well developed Effective reservoir ratio Mesa edge 7 0 1 Open Terrace 3 2 0.6

[0069] Based on the statistical results, the scoring basis for the development probability of each reservoir forming condition is established:

[0070] ① Such as Figure 4 As shown in (a), based on the value of the vitrinite reflectance x of the source rock, the probability of the development of the source conditions is scored as follows:

[0071]

[0072] ② As shown in Table 1, based on the type of sedimentary facies, the probability of reservoir condition development is scored as follows:

[0073]

[0074] ③ Such as Figure 4 As shown in (b), according to the value of the cap layer thickness x, the probability of cap layer condition development is scored as follows:

[0075]

[0076] ④ Such as Figure 4 As shown in (c), according to the value of the distance x from the oil source fault, the probability of the development of the transport condition is scored as follows:

[0077]

[0078] S103, converting the oil and gas accumulation condition parameter factor plane diagram into an oil and gas accumulation condition development probability plane diagram according to the scoring basis;

[0079] The specific process is:

[0080] The correspondence between each parameter factor data and the probability of development of oil and gas accumulation conditions in the parameter factor plane diagram of oil and gas accumulation conditions is fitted, so as to obtain the correspondence law between the parameter factor and the probability of development of oil and gas accumulation conditions. According to the correspondence law, the development probability is calculated within the scope of the mining right to form a plane diagram of the probability of development of oil and gas accumulation conditions, wherein the scope of each parameter factor data obtained is the wells within the structural geological unit to which the target to be evaluated belongs.

[0081] According to the scoring basis of the above-mentioned probability of reservoir formation conditions, the plane diagram of oil and gas reservoir formation condition parameter factors is converted into the plane diagram of oil and gas reservoir formation condition probability. The results are as follows: Figure 5 As shown. Since the vitrinite reflectance of the source rock is not less than 0.8, the probability of hydrocarbon source conditions in Block X is 1. In terms of reservoir conditions, the probability of development of the platform edge sedimentary facies belt is 1, and the probability of development of the open platform sedimentary facies belt is 0.6. In terms of cap rock conditions, the probability of development in the area with a cap rock thickness of not less than 60m is 1, and the probability of development in the area with a cap rock thickness of 50-60m is between (0.8,1). In terms of transport conditions, due to the development of oil source faults, the distance from all points to the oil source faults is less than 5km, so the probability of development of transport conditions in Block X is 1. In terms of trap conditions, the structural amplitude of exploration target 1 is greater than 60m, and the probability of development is 1; the structural amplitude of exploration target 2 is between 40m and 60m, and the probability of development is 0.75; the structural amplitude of exploration target 3 is between 20m and 40m, and the probability of development is 0.6.

[0083] The specific process is:

[0084] A1. According to the formula P H =P S *P R *P T *P C The probability of comprehensive oil and gas accumulation conditions is obtained, where P S is the probability of hydrocarbon source condition development, P R is the probability of reservoir condition development, P T is the probability of caprock condition development, P C is the probability of development of the transport condition, P H The probability of development of comprehensive oil and gas accumulation conditions;

[0085] A2. Draw a plane diagram of the probability of development of comprehensive oil and gas accumulation conditions based on the probability of development of comprehensive oil and gas accumulation conditions.

[0086] According to the calculation formula: P H =P S *P R *P T *P C , where P H is the probability of development of comprehensive oil and gas accumulation conditions, P S is the probability of hydrocarbon source condition development, P R is the probability of reservoir condition development, P T is the probability of caprock condition development, P C To calculate the probability of development of transport conditions, the four oil and gas accumulation conditions development probability plane maps are superimposed and multiplied to obtain the oil and gas comprehensive accumulation conditions development probability plane map. Figure 6 As shown, the probability of the development of comprehensive oil and gas accumulation conditions at the locations of exploration targets 1 and 2 is 1, and the probability of the development of comprehensive oil and gas accumulation conditions at the location of exploration target 3 is 0.6. It can be seen that the locations of exploration targets 1 and 2 have better comprehensive oil and gas accumulation conditions.

[0087] S105, superimposing the plane map of the probability of development of comprehensive oil and gas accumulation conditions with the plane position and trap condition score of the oil and gas exploration target, and calculating the product to obtain a plane distribution map of the geological success rate of the oil and gas exploration target.

[0088] The specific process is:

[0089] B1. According to formula P g =P H *P A The geological success rate of oil and gas exploration targets is obtained, where P AScoring the trap condition of the exploration target; in some embodiments, the specific process of obtaining the trap condition score is: scoring according to the structural amplitude of the trap where the oil and gas exploration target is located according to the seismic interpretation, and according to the regional statistical results of the relationship between the structural amplitude of the regional drilled trap and the oil and gas content.

[0090] The scoring of trap conditions is based on the structural amplitude of the trap where the oil and gas exploration targets are located according to seismic interpretation. The structural amplitude of the trap where exploration target 1 is located is 70m, the structural amplitude of the trap where exploration target 2 is located is 50m, and the structural amplitude of the trap where exploration target 3 is located is 30m.

[0091] The scores were calculated based on the regional statistical results of the relationship between the structural amplitude of the drilled traps and the oil and gas content. The statistical results are shown in Table 2:

[0092] Table 2 Statistical results of trap conditions of structural geological units to which oil and gas exploration targets belong

[0093] Trap structure amplitude (m) Oil Well Dry Well Oil and gas ratio in trap 20-40 3 2 0.6 40-60 3 1 0.75 60-80 3 0 1

[0094] Therefore, the trap condition score of exploration target 1 is 1, the trap condition score of exploration target 2 is 0.75, and the trap condition score of exploration target 3 is 0.6. Figure 7 shown.

[0095] B2. Draw a plan distribution map of the geological success rate of the oil and gas exploration target based on the geological success rate of the oil and gas exploration target.
