Description

Technical Field

[0001] This invention relates to the field of oil and gas exploration technology, specifically to a graphical comparison method, system, and equipment for assessing the geological success rate of oil and gas exploration targets. Background Technology

[0002] Oil and gas exploration targets are potential oil and gas traps identified through geological and geophysical studies within an exploration block. The geological success rate of an oil and gas exploration target is a data-driven reflection of the geological reliability evaluation results by technical personnel. It not only reflects the exploration potential of each target and helps in selecting the best drilling plan, but also assists oil company managers in understanding the resource potential of the block and developing reasonable exploration operation plans. Therefore, evaluating the geological success rate of exploration targets is a crucial aspect of oil and gas exploration project management.

[0003] The conventional technical approach for evaluating the geological success rate of oil and gas exploration targets involves identifying several parameters related to oil and gas accumulation, assigning development probabilities to each parameter through geological studies, and then multiplying these probabilities to determine the geological success rate of the exploration target. However, this method suffers from several drawbacks, including the subjectivity in determining the development probabilities of oil and gas accumulation parameters, and the lack of intuitive comparison of geological success rates across different exploration targets within a block. These issues hinder project managers from understanding the technical process and results of the approach, and from conducting cross-sectional comparisons of the evaluation results.

[0004] To improve the objectivity and visibility of the evaluation results of the geological success rate of oil and gas exploration targets, and to facilitate the intuitive understanding and comparison of relevant data by oil and gas exploration project managers, it is necessary to establish a graphical comparison method for the geological success rate of oil and gas exploration targets. Summary of the Invention

[0005] This invention provides a graphical comparison method, system, and equipment for the geological success rate of oil and gas exploration targets, which solves the problems of the subjective nature of the determination process of the development probability of oil and gas accumulation parameters in the existing technical solutions, and the lack of intuitiveness in the planar comparison of the accumulation conditions and geological success rates of different oil and gas exploration targets.

[0006] This invention is achieved through the following technical solution:

[0009] Based on the regional statistical results of the relationship between the aforementioned parameter factors and hydrocarbon accumulation conditions, a scoring basis for the probability of hydrocarbon accumulation conditions is established.

[0010] Based on the scoring criteria, the hydrocarbon accumulation condition parameter factor plane map is converted into a hydrocarbon accumulation condition development probability plane map;

[0011] By superimposing the development probability plane diagram of the oil and gas accumulation conditions, the product of each development probability in the development probability plane diagram of the oil and gas accumulation conditions is calculated to obtain the comprehensive development probability plane diagram of oil and gas accumulation conditions.

[0012] By superimposing the planar map of the probability of hydrocarbon accumulation conditions with the planar location and trap condition scores of the hydrocarbon exploration targets, the geological success rate distribution map of the hydrocarbon exploration targets is obtained by multiplying the product.

[0013] As an optimization, the hydrocarbon accumulation conditions corresponding to the drilling geological information include source conditions, reservoir conditions, and caprock conditions.

[0019] The probability of reservoir conditions being developed is scored based on the statistical results of the effective reservoir regions corresponding to each type of sedimentation.

[0020] The probability of the development of the caprock conditions is scored based on the statistical results of the effective oil and gas plugging area corresponding to the caprock thickness.

[0021] The probability of development of the transport conditions is scored based on the regional statistical results of the relationship between the distance from the oil source fracture and the effectiveness of fault transport.

[0022] As an optimization, based on the scoring criteria, the specific process of converting the hydrocarbon accumulation condition parameter factor plane map into a hydrocarbon accumulation condition development probability plane map is as follows:

According to the correspondence rule, the development probability is calculated within the mining right area to form an oil and gas accumulation condition development probability plane map. The range of each parameter factor data obtained is the wells within the tectonic geological unit to which the target to be evaluated belongs.

[0024] As an optimization, the specific process of calculating the product of each development probability in the development probability plane of the oil and gas accumulation conditions to obtain the comprehensive oil and gas accumulation condition development probability plane is as follows:

[0025] According to formula P H =P S *P R *P T *P C The probability of hydrocarbon accumulation conditions is obtained, where P S P represents the probability of hydrocarbon source conditions developing.

[0049] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0050] Example 1:

[0051] This embodiment uses the geological success rate evaluation of three oil and gas exploration targets in Block X as an example. In this embodiment, there are three wells within the mining rights area of ​​Block X, with full 3D seismic data coverage. These wells and seismic data are the data sources for hydrocarbon accumulation geological condition parameters. In addition, there are 12 wells outside Block X but within the same tectonic geological unit; these are the data sources for regional statistical analysis of the relationship between parameter factors and hydrocarbon accumulation 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, it includes:

[0053] S101. Read the parameter factors of hydrocarbon accumulation conditions from drilling geological information and corresponding seismic data geological interpretation results, and compile a hydrocarbon accumulation condition parameter factor plan map.

[0054] The hydrocarbon accumulation conditions used in evaluating the geological success rate of oil and gas exploration targets include hydrocarbon source, reservoir, caprock, and transport conditions.

[0055] The hydrocarbon accumulation conditions that require reading drilling geological information and seismic data geological interpretation results include source, reservoir, and caprock conditions. The source condition parameter factor is the vitrinite reflectance of the source rock, the reservoir condition parameter factor is the sedimentary facies of the strata to which the reservoir belongs, and the caprock condition parameter factor is the thickness of the strata to which the caprock belongs. The hydrocarbon accumulation conditions that only require reading seismic data geological interpretation results are the transport conditions, and the parameter factor is the distribution of oil source fractures.

[0056] In some embodiments, the specific process for constructing a hydrocarbon accumulation condition parameter factor plane map is as follows:

[0057] The hydrocarbon accumulation condition parameters corresponding to the drilling geological information related to the regional drilling are input in the form of data points, and the data range is the drilling within the mining rights area of ​​the block to which the target to be evaluated belongs;

[0058] The oil and gas accumulation 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. The interpretation results within the mining rights area of ​​the block to which the target to be evaluated belongs are obtained, thereby forming a planar map of oil and gas accumulation condition parameter factors.

[0059] Specifically, the source rock vitrinite reflectance, reservoir sedimentary facies, and caprock thickness information of wells A, B, and C are input as data points. The source rock vitrinite reflectance, reservoir sedimentary facies, caprock thickness, and oil source fracture interpretation results based on the 3D seismic data of block X are input as data grids. After overlaying the well point data and seismic grid data, interpolation is performed using the minimum curvature method. A parameter factor planar map of each hydrocarbon accumulation condition is then compiled within the scope of block X, as shown below. Figure 3 As shown.

[0060] S102. Based on the regional statistical results of the relationship between the parameter factors and the development of hydrocarbon accumulation conditions, establish a scoring basis for the probability of hydrocarbon accumulation conditions development;

[0061] Specifically, the specific method for establishing the scoring criteria for the probability of hydrocarbon accumulation conditions is as follows:

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

[0063] The probability of reservoir conditions being developed is scored based on the statistical results of the effective reservoir regions corresponding to each type of sedimentation.

[0064] The probability of the development of the caprock conditions is scored based on the statistical results of the effective oil and gas plugging area corresponding to the caprock thickness.

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

[0066] In this embodiment, the geological information of 12 wells within the structural geological unit and outside Block X was statistically analyzed. The distribution and trend fitting relationship of the hydrocarbon source, caprock, and transport conditions data points are as follows: Figure 4 As shown in Table 1, the statistical results of the reservoir conditions are as follows:

[0067] Table 1. Statistical results of reservoir conditions in the structural geological units to which oil and gas exploration targets belong.

[0068] sedimentary facies Reservoir development wells wells with underdeveloped reservoirs Effective reservoir ratio Plateau edge 7 0 1 open plateau 3 2 0.6

[0069] Based on the statistical results, a scoring basis for the development probability of each hydrocarbon accumulation condition was established:

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

[0071]

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

[0073]

[0074] ③ For example Figure 4 As shown in (b), based on the value of the cap layer thickness x, the probability score for cap layer development is:

[0075]

[0076] ④ For example Figure 4 As shown in (c), based on the value of the distance x from the oil source fracture, the probability score for the development of transport conditions is as follows:

[0077]

[0078] S103. Based on the scoring criteria, convert the hydrocarbon accumulation condition parameter factor plane map into a hydrocarbon accumulation condition development probability plane map.

[0079] The specific process is as follows:

[0080] The correspondence between the data of each parameter factor in the oil and gas accumulation condition parameter factor plane map and the development probability of oil and gas accumulation conditions is fitted to obtain the correspondence rule between the parameter factor and the development probability of oil and gas accumulation conditions. According to the correspondence rule, the development probability is calculated within the mining right area to form an oil and gas accumulation condition development probability plane map. The range of each parameter factor data obtained is the wells within the tectonic geological unit to which the target to be evaluated belongs.

[0081] Based on the scoring criteria for the probability of hydrocarbon accumulation development, the hydrocarbon accumulation condition parameter factor planar map was converted into a hydrocarbon accumulation condition development probability planar map, as shown in the figure. Figure 5 As shown. Since the reflectivity of the source rocks' vitrinite is not less than 0.8, the probability of source conditions developing in Block X is 1 for all of them. Regarding reservoir conditions, the probability of development of the platform margin sedimentary facies zone is 1, and the probability of development of the open platform sedimentary facies zone is 0.6. Regarding caprock conditions, the probability of development in areas with a caprock thickness of not less than 60m is 1, and the probability of development in areas with a caprock thickness of 50-60m is between (0.8, 1). Regarding transport conditions, due to the development of oil source faults, the distance from all points to the oil source faults is less than 5km, therefore the probability of transport conditions developing in Block X is 1 for all of them. Regarding trap conditions, the structural amplitude of exploration target 1 is greater than 60m, with a development probability of 1; the structural amplitude of exploration target 2 is between 40m and 60m, with a development probability of 0.75; and the structural amplitude of exploration target 3 is between 20m and 40m, with a development probability of 0.6.

[0082] S104. Overlay the development probability plane diagram of the oil and gas accumulation conditions, and calculate the product of each development probability in the development probability plane diagram of the oil and gas accumulation conditions to obtain the comprehensive development probability plane diagram of oil and gas accumulation conditions.

[0083] The specific process is as follows:

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

[0085] A2. Draw a planar diagram of the development probability of integrated hydrocarbon accumulation conditions based on the aforementioned development probability of integrated hydrocarbon accumulation conditions.

[0086] According to the calculation formula: P H =P S *P R *P T *P C , where P H P represents the probability of the development of comprehensive hydrocarbon accumulation conditions. S P represents the probability of hydrocarbon source conditions developing. R P represents the probability of reservoir condition development. T P represents the probability of conditional development of the cap layer. C To calculate the probability of hydrocarbon accumulation development, the development probability maps of the four hydrocarbon accumulation conditions were overlaid and multiplied to obtain the overall hydrocarbon accumulation condition development probability map. The results are as follows: Figure 6 As shown, the probability of the formation of comprehensive oil and gas reservoirs at the locations of exploration targets 1 and 2 is 1, while the probability of the formation of comprehensive oil and gas reservoirs at the location of exploration target 3 is 0.6. This indicates that the locations of exploration targets 1 and 2 have better comprehensive oil and gas reservoir conditions.

[0087] S105. By superimposing the above-mentioned oil and gas comprehensive accumulation condition development probability plan map with the planar location and trap condition score of the oil and gas exploration target, the geological success rate plan distribution map of the oil and gas exploration target is obtained by multiplying the product.

[0088] The specific process is as follows:

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

[0090] The trap condition score is based on the structural amplitude of the trap where the oil and gas exploration target is located, as interpreted by seismic analysis. 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 regional statistical results, which categorize the relationship between the extent of drilled trap structures and hydrocarbon potential, are shown in Table 2.

[0092] Table 2. Statistical Results of Trap Conditions of the Tectonic Geological Units to which Oil and Gas Exploration Targets Belong

[0093] Trap size (m) oil well dry well Oil and gas ratio of traps 20-40 3 2 0.6 40-60 3 1 0.75 60-80 3 0 1

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

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

[0096] According to the calculation formula: P g =P H *P A , where P g To determine the geological success rate of oil and gas exploration targets, P H P represents the probability of the development of comprehensive hydrocarbon accumulation conditions. A To score the trap conditions of the exploration target, the product of the probability of hydrocarbon accumulation and the trap condition score of the exploration target is used to calculate the planar distribution map of the geological success rate of the hydrocarbon exploration target. The results are as follows: Figure 8 As shown, the geological success rate of exploration target 1 is 1×1=1, the geological success rate of exploration target 2 is 1×0.75=0.75, and the geological success rate of exploration target 3 is 0.6×0.6=0.36. Therefore, the ranking of geological success rates is exploration target 1>exploration target 2>exploration target 3.

[0097] Example 2 also discloses a graphical comparison system for the geological success rate of oil and gas exploration targets, used to implement the aforementioned graphical comparison method for the geological success rate of oil and gas exploration targets, including:

[0098] The hydrocarbon accumulation condition parameter factor planar plotting module is used to read the parameter factors of hydrocarbon accumulation conditions from drilling geological information and the corresponding geological interpretation results of seismic data, in order to compile a hydrocarbon accumulation condition parameter factor planar plot.

[0099] The scoring criteria construction module is used to establish a scoring criteria for the probability of hydrocarbon accumulation conditions by referring to the regional statistical results of the relationship between the parameter factors and hydrocarbon accumulation conditions.

[0100] The hydrocarbon accumulation condition development probability plane map conversion module is used to convert the hydrocarbon accumulation condition parameter factor plane map into a hydrocarbon accumulation condition development probability plane map according to the scoring criteria.

[0101] The oil and gas accumulation condition development probability plane map construction module is used to overlay the oil and gas accumulation condition development probability plane map and calculate the product of each development probability in the oil and gas accumulation condition development probability plane map.

[0102] The oil and gas exploration target geological success rate planar distribution map construction module is used to overlay the oil and gas comprehensive accumulation condition development probability planar map with the planar location and trap condition score of the oil and gas exploration target, and calculate the oil and gas exploration target geological success rate planar distribution map by multiplying the product.
