Description

Technical Field

[0001] The present invention relates to the technical field of oil reservoir development, and in particular to a method and device, equipment and medium for finely determining well-controlled geological reserves. Background Art

[0002] When calculating geological reserves in oil fields, the volumetric method is often used. The parameters for calculating reserves in the volumetric method include area, thickness, porosity, saturation, etc. At present, the commonly used method to determine the area is to start from the control area of ​​a single well, calculate the control area of ​​a single well using the triangulated network method, and calculate the geological reserves of different types of sand bodies in a single well according to the single reserve coefficient of different types of sand bodies in the control area of ​​a single well, and then determine the geological reserves of different types of sand bodies in a single well, well group and block.

[0003] However, in the face of deltaic sedimentary systems, from rivers to deltas, from above water to underwater, the sedimentary environment is complex and the reservoir development is complete, including different types of sand bodies such as river sand, overflow sand, sheet sand and sand dam. The sand body development is diverse and the plane phase change is frequent. Even under the conditions of dense well network, the microphase changes in the same well group are very complex. There is often more than one type of microphase, and usually multiple microphases exist at the same time. Moreover, the phase boundary is not strictly divided according to half of the well spacing. The reserves of the well group calculated by the triangulated network method do not take into account the development of sedimentary facies belts and the boundary trend in terms of area. It is more reasonable when calculating the reserves of larger blocks, but when calculating single wells and well groups, especially sedimentary units with more complex phase belt changes within the well group, the unreasonable reserve calculation is more prominent, which is inconsistent with the development effect, dynamic analysis and understanding.

[0047] Figure 1 A flow chart showing a method for finely determining well-controlled geological reserves according to an embodiment of the present invention; Figure 2 A block diagram of an electronic device 800 according to an embodiment of the present invention is shown; Figure 3 FIG. 1 is a block diagram of an electronic device 1900 according to an embodiment of the present invention. Figure 1-3 As shown, a method for finely determining well-controlled geological reserves includes: step S01: obtaining a sedimentary facies map and a well point distribution map in a study area; step S02: extracting phase boundaries of different sedimentary facies in the study area from the sedimentary facies map, projecting the extracted phase boundaries of different sedimentary facies onto the well point distribution map, and generating the well point distribution map with phase attributes; step S03: gridding the well point distribution map with phase attributes to determine the sand body type and sand body thickness at each grid node; step S04: determining the geological reserves corresponding to each grid node according to the sand body type and sand body thickness; step S05: determining the sedimentary unit geological reserves according to the geological reserves corresponding to each grid node.

[0048] The method for finely determining well-controlled geological reserves provided by the embodiment of the present invention specifically includes the following steps:

[0049] Step S01: Obtain a sedimentary facies map and a well point distribution map within the study area.

[0050] In the embodiment of the present invention, the sedimentary facies map is drawn based on the well logging data in the study area, and the sedimentary facies map can reflect the microfacies types and corresponding facies attribute values ​​at various locations in the study area.

[0051] Step S02: In the sedimentary facies map, extract the phase boundaries of different sedimentary facies in the study area, project the extracted phase boundaries of different sedimentary facies onto the well point distribution map, and generate the well point distribution map with phase attributes.

[0052] In an embodiment of the present invention, first, the phase boundaries of different sedimentary phase belts in the study area are extracted, and the extracted phase boundaries of different phase belts are projected onto the well point distribution map of the study area, thereby forming a well point distribution map with phase attributes, which can reflect the phase attribute values ​​and sedimentary microfacies types corresponding to each location in the study area.

[0053] Step S03: gridding the well point distribution map with phase attributes to determine the sand body type and thickness at each grid node.

[0054] In the present invention, the method for determining the sand body type and sand body thickness at each grid node comprises: extracting the phase attribute value corresponding to each grid node on the well point distribution map with phase attributes; according to the phase attribute value, identifying the sand body type at each grid node on the well point distribution map with phase attributes and predicting the sand body thickness, so as to obtain the sand body type and sand body thickness at each grid node.

[0055] In an embodiment of the present invention, the study area is gridded, that is, the area is divided into rectangular grids at a certain interval according to the distribution and number of discrete points in the area, which is conducive to engraving regular boundary areas; the grid size is adjusted according to the accuracy requirements to be met.

[0056] Extract phase attributes on the well point distribution map with phase attributes according to grid nodes. Each node has an exact phase attribute value and is already gridded. The extracted phase attribute file format is a text file, that is, the grid node coordinates and the corresponding phase belt attribute value.

[0057] The grid nodes only correspond to the phase attribute values, but not the sand body type and thickness. Therefore, it is necessary to predict the sand body type and thickness at the grid nodes based on the sand body type and thickness corresponding to the known well points.

[0058] On the well point distribution map with phase attributes, the sand body type at the grid node in the sedimentary microfacies where each well point is located is consistent; if the phase attribute values ​​are consistent and continuously distributed, the sand body thickness is consistent, thus completing the sand body type identification and thickness prediction under phase constraints.

[0059] Step S04: Determine the geological reserves corresponding to each grid node according to the sand body type and sand body thickness.

[0060] In the present invention, the method for determining the geological reserves corresponding to each grid node according to the sand body type and sand body thickness comprises: determining the area of ​​each grid on the well point distribution map with phase attributes; determining the corresponding single reservoir coefficient according to the sand body type; and calculating the geological reserves corresponding to each grid node using the volumetric method according to the area, single reservoir coefficient and sand body thickness of the grid.

[0061] In the present invention, the calculation formula of the volumetric method includes:

[0062] N=100AhφSoρo / Boi=Ahω

[0063] ω=100φSoρo / Boi

[0064] Where: N is geological reserves, 10 4 t, A is the oil-bearing area, km 2, h is the effective thickness, m, φ is the effective porosity, %, S o is the original oil saturation, %, ρ o is the density of ground degassed crude oil, t / m 3 , B oi is the surface crude oil volume coefficient, dimensionless, ω is the single storage coefficient, 10 4 t / (km 2 ·m).

[0065] In the embodiment of the present invention, since the grid in the study area is uniform, the area of ​​each grid node (oil-bearing area A) can be determined according to the grid size, and then the geological reserves of different types of sand bodies corresponding to each grid node are calculated using the volumetric method based on the sand body type identified under phase constraints and the predicted sand body thickness (effective thickness h).

[0066] Among them, the single reserve coefficient used in the volumetric method is calculated through the porosity and saturation parameters of the core analysis data in the coring well analysis data. Its value corresponds to the sand body type, that is, different sand body types correspond to different single reserve coefficients. In this way, the geological reserves at the grid nodes can be obtained through the volumetric method.

[0067] Step S05: Determine the geological reserves of the sedimentary unit according to the geological reserves corresponding to each grid node.

[0068] In the present invention, the method for determining the geological reserves of a sedimentary unit according to the geological reserves corresponding to each grid node comprises: using the triangulated network method to determine the single well control area in the study area; determining the single well geological reserves according to the geological reserves corresponding to each grid node and the single well control area; and determining the sedimentary unit geological reserves according to the single well geological reserves.

[0069] In an embodiment of the present invention, the single well control area is determined by the triangulated network method, and the partial area composed of the grids within the single well control area is the single well control area determined by the grid method; the geological reserves of different types of sand bodies corresponding to each grid node within the single well control area are accumulated to obtain the geological reserves within the single well control area determined by the grid method (i.e., well-controlled geological reserves); the geological reserves within the single well control area determined by the grid method are accumulated to determine the geological reserves of different types of sand bodies in the sedimentary units in the study area.

[0070] In order to verify the accuracy of the method of the present invention in calculating the control area of ​​a single well and the precision of the reserves calculation, a 200*200 simulated five-point well network was designed, and the control area and reserves of a single well were calculated using a 10*10 grid and a 2*2 grid, respectively, and compared with the calculation results of the existing direct use of the triangulated network method. The comparison results of the control area of ​​a single well are shown in Table 1 below, and the comparison results of the reserves calculation are shown in Table 2 below.

[0071] Table 1 Comparison of single well control area based on five-point method test data

[0072] well name Grid method 10*10 Grid method 2*2 Triangulation 1 0.0061 0.00664 0.00665 2 0.0067 0.00667 0.00668 3 0.0071 0.0067 0.0067 4 0.0067 0.00667 0.00668 5 0.0134 0.01333 0.0133 total 0.04 0.04001 0.04001

[0073] As can be seen from Table 1, this method determines the accuracy of the calculation result of the single well control area by the number of grids, and its accuracy is related to the grid density. The denser the grid, the higher the calculation accuracy.

[0074] Table 2 Comparison of geological reserve accuracy of five-point method test data

[0075] On-balance sheet reserves Accuracy Off-balance sheet reserves Accuracy total Accuracy Triangulation 1.354 / 0.655 / 2.009 / Grid method 2×2 1.409 95.9％ 0.625 95.4％ 2.034 98.8％ Grid method 10×10 1.414 95.6％ 0.626 95.6％ 2.04 98.5％

[0076] Among them, the on-balance sheet reserves refer to the geological reserves that can obtain economic benefits after being mined under the current mining technology and economic conditions; the off-balance sheet geological reserves refer to the geological reserves that cannot obtain economic benefits after being mined under the current mining technology and economic conditions, but can obtain economic benefits when the mining technology and crude oil prices are improved, or the oil field adopts measures such as densification adjustment and fracturing transformation. At this time, the off-balance sheet reserves can be converted into on-balance sheet reserves.

[0077] It can be seen from Table 2 that the geological reserve calculation of this method is accurate. After precision comparison and analysis, the accuracy is highest under 2*2 grid, and the geological reserve calculation accuracy reaches 98.8%.

[0078] It can be understood that the above-mentioned various method embodiments mentioned in the present invention can be combined with each other to form a combined embodiment without violating the principle logic. Due to space limitations, the present invention will not go into details.

[0079] The execution subject of the well-controlled geological reserve fine determination method may be a well-controlled geological reserve fine determination device, for example, the well-controlled geological reserve fine determination method may be executed by a terminal device or a server or other processing device, wherein the terminal device may be a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. In some possible implementations, the well-controlled geological reserve fine determination method may be implemented by a processor calling a computer-readable instruction stored in a memory.

[0080] Those skilled in the art will appreciate that, in the above method of specific implementation, the order in which the steps are written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of the steps should be determined by their functions and possible internal logic.

[0081] The present invention also provides a well-controlled geological reserve fine determination device, comprising: an acquisition unit, used for acquiring a sedimentary phase belt map and a well point distribution map in a study area; a phase attribute well point map generation unit, used for extracting the phase boundaries of different sedimentary phase belts in the study area from the sedimentary phase belt map, projecting the extracted phase boundaries of different sedimentary phase belts onto the well point distribution map, and generating the well point distribution map with phase attributes; a sand body type and thickness determination unit, used for gridding the well point distribution map with phase attributes, and determining the sand body type and sand body thickness at each grid node; a grid node geological reserve determination unit, used for determining the geological reserves corresponding to each grid node according to the sand body type and sand body thickness; and a sedimentary unit geological reserve determination unit, used for determining the sedimentary unit geological reserves according to the geological reserves corresponding to each grid node.

Its specific implementation can refer to the description of the above method embodiment. For the sake of brevity, it will not be repeated here.

[0083] In order to solve the problem that conventional calculation methods do not take sedimentary factors into consideration, the present invention focuses on the "sedimentary combination characteristics" to form a fine calculation method for well-controlled geological reserves under sedimentary phase constraints, which solves the problem that the controlled area of ​​a single well in a well group cannot accurately reflect the phase type and cannot accurately calculate the geological reserves reflecting the unit sedimentary characteristics, and plays a positive role in improving the accuracy of reserve calculation.
