Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas geological resource evaluation, and in particular to a vectorized oil and gas geological resource evaluation method, system, terminal and medium. Background Art

[0002] Oil and gas geological resources are determined by professionals based on research into reservoir formation patterns. Professionals conduct evaluations and obtain resource data for geological units such as basins / depressions, sags, migration and accumulation units, zones or blocks, and strata zones, strictly following evaluation standards and processes. This resource data is reviewed for rationality by an expert panel before being released by the company. This authoritative resource data serves as a crucial basis for planning, exploration, and deployment decisions. Oil and gas geological resource evaluation research is characterized by strict standards, a high level of professionalism, a significant workload, and a lengthy evaluation process.

[0003] Rapidly obtaining the amount of oil and gas geological resources within any range is an inevitable requirement for planning and exploration deployment decision-making. However, resource evaluation data only supports single-item queries, and it is impossible to quickly obtain the amount of oil and gas geological resources within any range from resource evaluation data. If you want to obtain the amount of oil and gas geological resources within any range, researchers need to conduct re-evaluation research based on user needs. This is a heavy workload, time-consuming, and influencing factor. The evaluation results are affected by factors such as the professional ability of researchers, evaluation methods, and key parameter selection. It is difficult to ensure that the sum of the resources within any range is consistent with the total amount of oil and gas geological resources, and the data lacks authority. Summary of the Invention

[0004] In order to overcome the defects of the above-mentioned prior art, the purpose of the present invention is to provide a method, system, terminal and medium for calculating vectorized oil and gas geological resources, so as to solve the technical problems in the prior art such as the inability to quickly obtain oil and gas geological resources within any range from resource evaluation data, the difficulty in ensuring that the sum of resources within any range is consistent with the total oil and gas geological resources, and the lack of authoritative data.

[0005] The present invention is achieved through the following technical solutions:

[0006] A method for calculating vectorized oil and gas geological resources comprises the following steps:

[0007] Step 1: extracting the oil and gas geological resource evaluation parameters of the original evaluation unit;

[0008] Step 2: Divide the evaluation unit into several bins based on the basin's oil and gas geological characteristics, spatial distribution characteristics of geological resources, and sedimentary systems, and input the extracted oil and gas geological resource evaluation parameters of the original evaluation unit into any of the divided bins;

[0009] Step 3, calculating the resource quantity of all bins in sequence according to the bin resource quantity calculation formula of the input oil and gas geological resource evaluation parameters of the original evaluation unit, and obtaining the resource abundance and resource quantity of all bins;

[0010] Step 4: Grid all the facets, parse the boundary coordinates of each facet, and use the calculation unit number in each facet as a unique identifier. Project the boundary line into the gridded facet according to the user-specified range, and circle the overlapping area between the specified range and the facet grid. After calculating the resource volume of each projection in turn, add up the resource volume of each projection to obtain the oil and gas geological resource volume of the specified range.

[0011] Preferably, in step 1, the oil and gas geological resources of the original evaluation unit include the oil and gas geological resources of the original basin / depression-level evaluation unit, the oil and gas geological resources of the original sag-level evaluation unit, the oil and gas geological resources of the original migration and accumulation unit-level evaluation unit, the oil and gas geological resources of the original zone or block-level evaluation unit, and the oil and gas geological resources of the original layer zone-level evaluation unit.

[0012] Preferably, in step 3, the calculation formula for the resource quantity of the bin of the oil and gas geological resource evaluation parameter of the original evaluation unit is as follows:

[0013] The first oil and gas geological resources Q1 of the bin element is obtained by calculating the effective storage space of the reservoir and its oil and gas content using the volumetric method. The calculation formula of the first oil and gas geological resources Q1 is as follows:

[0014] Q1=100·A·C a ·H·φ·ρ·S o / B

[0015] Wherein, Q1 is the first oil and gas geological resources; A is the trap area, m2; Ca is the oil-bearing area coefficient; H is the effective reservoir thickness, m; φ is the reservoir porosity; So is the oil saturation; ρ is the crude oil density; B is the volume coefficient;

[0016] The second oil and gas geological resources Q2 of the bin is calculated using the resource abundance analogy method. The calculation formula for the second oil and gas geological resources Q2 is as follows:

[0017]

[0018] Among them, Q2 is the second oil and gas geological resources, the unit is 10 8 t; Si is the area of ​​the analogy unit in the evaluation area, in km 2 ; Ki is the area abundance of oil resources in the scale area, unit is 10 8 t / Km 2 ; ai is the similarity coefficient between the evaluation area and the scale area; i is the number of sub-areas in the evaluation area;

[0019] The calculation formula for the resource quantity of the bin of the oil and gas geological resource evaluation parameters of the original evaluation unit is Q=Q1*a+Q2*b;

[0020] Wherein, a is the first weight coefficient, b is the second weight coefficient, and a+b=1.

[0021] Preferably, in step 3, the resource quantity of all bins is calculated in sequence according to the resource quantity calculation formula of the bin of the oil and gas geological resource evaluation parameters inputted into the original evaluation unit, and the resource abundance and resource quantity of all bins are obtained; the sum of the resource quantities of all bins is compared with the total oil and gas geological resources of the original evaluation unit. If the sum of the resource quantities of all bins is inconsistent with the total oil and gas geological resources of the original evaluation unit, the oil and gas geological characteristics and the spatial distribution characteristics of the geological resources of each bin are re-evaluated and the oil and gas geological resource evaluation parameters are adjusted. The oil and gas geological resources of each bin are recalculated, and the resource quantity of all bins is re-iterated until the sum of the resource quantities of all bins is equal to the total oil and gas geological resources of the original evaluation, and the resource abundance and resource quantity of all bins are obtained.

[0022] Furthermore, the volumetric method and resource abundance analogy method are used to calculate the resource volume of all bins. The volumetric method calculates the first oil and gas geological resource volume Q1 of the bin; the resource abundance analogy method calculates the second oil and gas geological resource volume Q2 of the bin. Different weights are assigned to the volumetric method and the resource abundance analogy method according to the exploration degree of the bin. The bins with high exploration degree are assigned higher weights by the volumetric method, and the bins with low exploration degree are assigned higher weights by the resource abundance analogy method.

[0023] Preferably, in step 4, the boundary line is projected into the gridded bins according to the user-specified range, and the overlapped area between the specified range and the bin grid is circled, and each projection unit is numbered A1, A2, A3...A i , calculate the area F of each projection unit i The resource volume of each projection unit can be calculated in turn by multiplying the area ratio of the gridded surface element it occupies by the surface element resource volume. Finally, the total sum can be calculated to calculate the oil and gas geological resource volume in the user-specified range.

[0024] Furthermore, the calculation formula for oil and gas geological resources within the user-specified range is as follows:

[0025]

[0026] Where Q is the total oil and gas resources within the user-specified range, in units of 10 8 t; Fi is the area of ​​each projection unit, in km 2 ; Si is the area of ​​the grid element to which the projection unit belongs, in km 2 ;Q iThe oil and gas geological resource quantity of the cell is 10 8 t; i is the number of projection units; j is the number of cells occupied by the projection unit.

[0038] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0039] The present invention is described in further detail below with reference to the accompanying drawings:

[0040] The purpose of the present invention is to provide a method, system, terminal and medium for calculating vectorized oil and gas geological resources, so as to solve the technical problems in the prior art such as the inability to quickly obtain oil and gas geological resources within any range from resource evaluation data, the difficulty in ensuring that the sum of resources within any range is consistent with the total oil and gas geological resources, and the lack of authoritative data.

[0041] See also Figure 1 In one embodiment of the present invention, a method for calculating vectorized oil and gas geological resources is provided, comprising the following steps:

[0042] Step 1: extracting the oil and gas geological resource evaluation parameters of the original evaluation unit;

[0043] Specifically, the original evaluation unit oil and gas geological resources include original basin / sag level evaluation unit oil and gas geological resources, original depression level evaluation unit oil and gas geological resources, original migration unit level evaluation unit oil and gas geological resources, original zone or block level evaluation unit oil and gas geological resources, and original layer zone level evaluation unit oil and gas geological resources.

[0044] Step 2, according to the characteristics of the basin oil and gas geology, the spatial distribution characteristics of the geological resources, and the sedimentary system, the evaluation unit is divided into a plurality of cells, and the extracted original evaluation unit oil and gas geological resource evaluation parameters are input into any one of the divided cells;

[0045] Step 3, according to the resource amount calculation formula of the cell of the input original evaluation unit oil and gas geological resource evaluation parameters, the resource amount of all cells is calculated in turn, and the resource abundance and resource amount of all cells are obtained;

[0046] Wherein, the cell area can be constructed by multiple geodetic points according to the evaluation needs of oil and gas geological resources, and mature methods such as volume method and resource abundance analogy method are selected to evaluate the resource amount of the cell.

[0047] Specifically, the resource amount calculation formula of the cell of the input original evaluation unit oil and gas geological resource evaluation parameters is as follows:

[0048] The first oil and gas geological resource amount Q1 of the cell is obtained by calculating the effective reservoir space and the oil and gas content through the volume method, and the oil and gas geological resource amount in the effective reservoir is estimated, wherein the calculation formula of the first oil and gas geological resource amount Q1 is as follows:

[0049] Q1=100·A·C a ·H·φ·ρ·S o / B

[0050] Wherein, Q1 is the first oil and gas geological resource amount; A is the trap area, m2; Ca is the oil-bearing area coefficient; H is the effective reservoir thickness, m; φ is the reservoir porosity; So is the oil saturation; ρ is the oil density; B is the volume coefficient;

[0051] The second oil and gas geological resource amount Q2 of the cell is calculated by using the resource abundance analogy method, wherein the calculation formula of the second oil and gas geological resource amount Q2 is as follows:

[0052]

[0053] Wherein, Q2 is the second oil and gas geological resource amount, unit is 10 8 t; Si is the area of the evaluation zone analogy unit, unit is Km 2 ; Ki is the petroleum resource area abundance of the calibration zone, unit is 10 8 t / Km2 ; ai is the similarity coefficient between the evaluation area and the scale area; i is the number of sub-areas in the evaluation area;

[0054] The resource area abundance analogy method uses known areas to infer unknown areas. Its application assumes that an evaluation area and a highly explored analogy area have similar reservoir-forming geology, and therefore will have roughly the same hydrocarbon abundance. Based on the principles of high exploration level, high geological understanding, and high proven resource level, the scaled areas were selected for detailed analysis, serving as the basis for geological analogy calculations.

[0055] The calculation formula for the bin resource quantity of the input oil and gas geological resource evaluation parameters of the original evaluation unit is Q=Q1*a+Q2*b;

[0056] Wherein, a is the first weight coefficient, b is the second weight coefficient, and a+b=1.

[0057] By analogy between the evaluation unit and the scale area, the resource area abundance and migration and concentration coefficient of the evaluation unit are obtained.

[0058] Core parameter: Similarity coefficient. To determine the similarity coefficient, a calibration area (known high-exploration area) and an evaluation area (unknown low-exploration area) must be established to compare reservoir-forming geological conditions. Based on the results of the calibration area analysis, a detailed statistical analysis of 43 key parameters across five categories was conducted to serve as the basis for the comparison and evaluation (Table 1).

[0059] Table 1. Parameter system for oil and gas geological resource evaluation in oil and gas basin geological zones

[0060]

[0061]

[0062] To achieve this comparison, geological risk assessment criteria and scoring tables were established for the calibration and evaluation areas based on reservoir-forming geology and 43 key parameters. To account for the differences in reservoir-forming geology, scoring tables for geological risk analysis and evaluation criteria were developed for unconventional and conventional reservoirs in petroliferous basins for comparison (Tables 2 and 3).

[0067]

[0068] Specifically, the resource quantity of all bins is calculated in sequence according to the resource quantity calculation formula of the bin of the oil and gas geological resource evaluation parameters inputted into the original evaluation unit, and the resource abundance and resource quantity of all bins are obtained; the sum of the resource quantities of all bins is compared with the total oil and gas geological resources of the original evaluation unit. If the sum of the resource quantities of all bins is inconsistent with the total oil and gas geological resources of the original evaluation unit, the oil and gas geological characteristics and the spatial distribution characteristics of the geological resources of each bin are re-evaluated, and the oil and gas geological resource evaluation parameters are adjusted. The oil and gas geological resources of each bin are recalculated, and the resource quantity of all bins is re-iterated and calculated again until the sum of the resource quantities of all bins is equal to the total oil and gas geological resources of the original evaluation, and the resource abundance and resource quantity of all bins are obtained.

[0069] The volumetric method and resource abundance analogy method are used to calculate resource quantities for all bins. The volumetric method calculates the first bin's oil and gas geological resource quantity, Q1, using evaluation parameters derived from the statistical results of relevant parameters of submitted reserves within the evaluation area (bin). The resource abundance analogy method calculates the second bin's oil and gas geological resource quantity, Q2, using evaluation parameters derived from interpreted reservoir thickness from industrial oil wells and oil-bearing display wells within the scale area and bin (evaluation area), combined with well logging, mud logging, physical properties, and oil testing data. Different weights are assigned to the two methods based on the exploration level of the bin, with the volumetric method receiving a higher weight for bins with a higher exploration level, and the resource abundance analogy method receiving a higher weight for bins with a lower exploration level.

[0070] Step 4: Grid all the facets, parse the boundary coordinates of each facet, and use the calculation unit number in each facet as a unique identifier. Project the boundary line into the gridded facet according to the user-specified range, and circle the overlapping area between the specified range and the facet grid. After calculating the resource volume of each projection in turn, add up the resource volume of each projection to obtain the oil and gas geological resource volume of the specified range.

[0071] Specifically, according to Figure 2 As shown in the figure, according to the user-specified range, the boundary line is projected into the gridded surface element, and the overlapping area between the specified range and the surface element grid is circled, and each projection unit is numbered as A1, A2, A3...A i , calculate the area F of each projection unit i The resource volume of each projection unit can be calculated in turn by multiplying the area ratio of the gridded surface element it occupies by the surface element resource volume. Finally, the total sum can be calculated to calculate the oil and gas geological resource volume in the user-specified range.

[0072] The calculation formula for oil and gas geological resources within the user-specified range is as follows:

[0073]

[0074] Where Q is the total oil and gas resources within the user-specified range, in units of 10 8 t; Fi is the area of ​​each projection unit, in km 2 ; Si is the area of ​​the grid element to which the projection unit belongs, in km 2 ;Q i The amount of oil and gas geological resources per unit is 10 8 t; i—the number of projection units; j—the number of facets occupied by the projection units.

[0075] In summary, the present invention provides a method for calculating vectorized oil and gas geological resources. The method extracts oil and gas geological resource evaluation parameters of an original evaluation unit and divides the evaluation unit into a number of bins according to the oil and gas geological characteristics of the basin, the spatial distribution characteristics of geological resources, and the sedimentary system. The extracted oil and gas geological resource evaluation parameters of the original evaluation unit are applied to the divided bins. The resource quantities of all bins are calculated in sequence according to the resource quantity calculation formula of the bins, and the resource abundance and resource quantity of all bins are obtained. All bins are gridded and the boundary coordinates of each bin are parsed. The specified range can be projected according to the user-specified range, and the projected area is calculated. The oil and gas geological resources in the specified range can be quickly calculated. The oil and gas geological resources in any range can be quickly obtained in all bins under the premise that the sum of the resource quantities in any range is guaranteed to be consistent with the total amount of oil and gas geological resources, thereby improving data accuracy.

[0079] The second data calculation module is used to calculate the resource quantity of all bins in turn according to the resource quantity calculation formula of the bin of the oil and gas geological resource evaluation parameter inputted into the original evaluation unit, and obtain the resource abundance and resource quantity of all bins;

[0080] The third data calculation module is used to grid all the surface elements, parse the boundary coordinates of each surface element, and use the calculation unit number in each surface element as a unique identifier. According to the user-specified range, the boundary line is projected into the gridded surface element, and the overlapping area between the specified range and the surface element grid is circled. After calculating the resource amount of each projection in turn, the resource amount of each projection is added together to obtain the oil and gas geological resource amount of the specified range.
