Technical Field

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

[0002] Oil and gas geological resources are obtained by professionals on the basis of reservoir formation law research, targeting basins / depressions, sags, migration and accumulation units, zones or blocks, layers and zones, etc., strictly following evaluation standards and processes to carry out evaluation work and obtain corresponding geological unit resource data. The resource data must be reviewed for rationality by an expert group and finally released by the company. The resource data is authoritative and is an important basis for planning and exploration deployment decisions. Oil and gas geological resource evaluation research is characterized by strict standard requirements, high professionalism, large workload, and long evaluation time.

[0003] Rapidly obtaining the amount of oil and gas geological resources within any range is an inevitable requirement for planning and exploration deployment decisions. 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. The workload is large, time-consuming, and there are many influencing factors. The evaluation results are affected by factors such as the business capabilities of researchers, evaluation methods, and key parameter selection. It is difficult to ensure that the sum of 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

[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 facets according to the oil and gas geological characteristics, spatial distribution characteristics of geological resources and sedimentary system of the basin, and input the extracted oil and gas geological resource evaluation parameters of the original evaluation unit into any of the divided facets;

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

[0010] Step 4: Grid all the face elements, parse the boundary coordinates of each face element, and use the calculation unit number in each face element as a unique identifier. According to the user-specified range, project the boundary line into the gridded face element, and circle the overlapping area between the specified range and the face element 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 original evaluation unit oil and gas geological resources include original basin / depression-level evaluation unit oil and gas geological resources, original sag-level evaluation unit oil and gas geological resources, original migration and accumulation 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.

[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 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:

[0022] Furthermore, when calculating the resource volume of all cells, the volumetric method and the resource abundance analogy method are used. The volumetric method calculates the first oil and gas geological resource volume Q1 of the cell; the resource abundance analogy method calculates the second oil and gas geological resource volume Q2 of the cell; different weights are assigned to the volumetric method and the resource abundance analogy method according to the exploration degree of the cell. The volumetric method is assigned a higher weight to the cell with a high exploration degree, and the resource abundance analogy method is assigned a higher weight to the cell with a low exploration degree.

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

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

[0038] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme 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 described embodiments 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 creative work should fall within the scope of protection of the present invention.

[0039] The present invention is further described in detail below in conjunction with 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 that the oil and gas geological resources within any range cannot be quickly obtained from resource evaluation data, 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.

[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 the original basin / depression-level evaluation unit oil and gas geological resources, the original sag-level evaluation unit oil and gas geological resources, the original migration and accumulation unit-level evaluation unit oil and gas geological resources, the original zone or block-level evaluation unit oil and gas geological resources and the original layer zone-level evaluation unit oil and gas geological resources.

[0044] Step 2: According to the oil and gas geological characteristics, spatial distribution characteristics of geological resources and sedimentary system of the basin, the evaluation unit is divided into several facets, and the extracted oil and gas geological resource evaluation parameters of the original evaluation unit are input into any of the divided facets;

[0045] Step 3, calculating the resource quantity of all bins in turn according to the bin resource quantity calculation formula of the input original evaluation unit oil and gas geological resource evaluation parameter, and obtaining the resource abundance and resource quantity of all bins;

[0046] Among them, the surface element area can be constructed from multiple points through multiple geodetic coordinate points according to the needs of oil and gas geological resource evaluation, and mature methods such as volumetric method and resource abundance analogy method can be selected to evaluate the surface element resources.

[0047] Specifically, the calculation formula for the resource volume of the bin of the oil and gas geological resource evaluation parameters of the original evaluation unit is as follows:

[0048] The volumetric method is used to calculate the effective storage space of the reservoir and its oil and gas content to obtain the first oil and gas geological resources Q1 of the bin, and to estimate the oil and gas geological resources in the effective reservoir. The calculation formula of the first oil and gas geological resources Q1 is as follows:

[0049] Q1=100·A·C a ·H·φ·ρ·S o / B

[0050] Among them, Q1 is the first oil and gas geological resources; A is the closed 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;

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

[0052]

[0053] 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 / 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 is a method of inferring unknown areas from known areas. Its use condition is: assuming that a certain evaluation area and a certain high exploration degree analogy area have similar reservoir geological conditions, then they will have roughly the same oil and gas abundance. According to the division principles of high exploration degree, high geological understanding degree, and high resource proven degree, the scale area is selected for detailed dissection as the basis for carrying out geological analogy calculations.

[0055] The calculation formula of the area element resource quantity of the 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 obtain the similarity coefficient, it is necessary to establish a calibration area (known high exploration area) and an evaluation area (unknown low exploration area) to compare the geological conditions of reservoir formation. For the analogy, based on the results of the calibration area dissection, a total of 43 key parameters in five categories were selected for detailed statistical analysis as the basis for analogy and evaluation (Table 1).

[0059] Table 1. Evaluation parameter system of oil and gas geological resources in oil and gas basin geological zones

[0060]

[0061]

[0062] In order to achieve analogy, geological risk evaluation standards and scoring tables for calibration areas and evaluation areas were established based on reservoir geological conditions and 43 key parameters. Based on the differences in reservoir geological conditions, geological risk analysis and evaluation standard scoring tables for unconventional oil and gas reservoirs and conventional oil and gas reservoirs in oil and gas basins were established for analogy (Table 2, Table 3).

[0067]

[0068] Specifically, the resource quantity of all the facets is calculated in turn according to the resource quantity calculation formula of the facet of the oil and gas geological resource evaluation parameters input into the original evaluation unit, and the resource abundance and resource quantity of all the facets are obtained; the sum of the resource quantities of all the facets is compared with the total oil and gas geological resources of the original evaluation unit. If the sum of the resource quantities of all the facets 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 facet are re-evaluated, and the oil and gas geological resource evaluation parameters are adjusted, the oil and gas geological resources of each facet are recalculated, and the resource quantity of all the facets is re-iteratively calculated until the sum of the resource quantities of all the facets is equal to the total oil and gas geological resources of the original evaluation, and the resource abundance and resource quantity of all the facets are obtained.

[0069] Among them, the volumetric method and resource abundance analogy method are used to calculate the resource volume of all bins. The volumetric method calculates the first bin oil and gas geological resource volume Q1, and the evaluation parameters are all from the statistical results of the relevant parameters of the submitted reserves in the evaluation area (bin); the resource abundance analogy method calculates the second bin oil and gas geological resource volume Q2, and the evaluation parameters are all from the oil layer thickness interpreted by the industrial oil wells and oil-bearing display wells in the scale area and bin (evaluation area), combined with logging, mud logging, physical properties, oil testing data, etc. Different weights are given to the two methods according to the exploration degree of the bin. The bin volumetric method with a high exploration degree is given a higher weight, and the bin resource abundance analogy method with a low exploration degree is given a higher weight.

[0070] Step 4: Grid all the face elements, parse the boundary coordinates of each face element, and use the calculation unit number in each face element as a unique identifier. According to the user-specified range, project the boundary line into the gridded face element, and circle the overlapping area between the specified range and the face element 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 overlap 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 area ratio of the gridded surface element it occupies and then multiply it by the surface element resource volume can be calculated in turn to calculate the resource volume of each projection unit. Finally, the sum of the two can be calculated to calculate the oil and gas geological resources 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] Among them, 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 gridded surface element to which the projection unit belongs, in km 2 ;Q i The amount of oil and gas geological resources per unit, in units of 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, which extracts the oil and gas geological resource evaluation parameters of the original evaluation unit, and divides the evaluation unit into a number of facets according to the oil and gas geological characteristics of the basin, the spatial distribution characteristics of the geological resources, and the sedimentary system; applies the extracted oil and gas geological resource evaluation parameters of the original evaluation unit to the divided facets; calculates the resource quantities of all facets in turn according to the resource quantity calculation formula of the facets, and obtains the resource abundance and resource quantity of all facets; grids all facets, parses the boundary coordinates of each facet, and can project the specified range according to the user-specified range, calculate the projection area, and quickly calculate the oil and gas geological resources in the specified range. The oil and gas geological resources in any range can be quickly obtained in all facets on the premise that the sum of the resources in any range is guaranteed to be consistent with the total amount of oil and gas geological resources, thereby improving data accuracy.
