[0002] Well testing can identify reservoir type, fluid flow capacity, formation pressure, and determine reservoir damage, etc. Therefore, well testing data obtained from well testing is an important basis for evaluating reservoir development effects and guiding injection and production adjustments.

[0003] In related technologies, during well testing, injection and production wells are randomly selected within the oilfield as test wells.

[0045] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0046] Well testing can identify reservoir type, fluid flow capacity, formation pressure, and reservoir damage. Therefore, it is a crucial tool for evaluating reservoir development effectiveness and guiding injection and production adjustments. During well testing, injection and production wells are randomly selected within the oilfield as test wells. These wells are then tested using a pre-determined testing method to generate test data. Common well testing methods include general testing and stratified testing. However, for reservoirs with strong vertical heterogeneity, general testing cannot generate test data that clearly reflects the vertical stratification of the reservoir and cannot reflect the influence of multiple layers. For reservoirs with weak vertical heterogeneity, stratified testing significantly increases the time and effort required for logging, increasing testing costs. Furthermore, the planar heterogeneity of reservoir parameters can lead to uneven distribution of reservoir physical properties across different blocks, making the interpretation of pressure buildup tests based on single-well logging data unrepresentative. Furthermore, the high number of shut-in wells for pressure testing conflicts with crude oil production, impacting normal oilfield production.

[0047] At present, the theory of reasonable well test deployment for pressure buildup testing is still imperfect. Therefore, from the perspective of well logging deployment plan, reasonable single well testing methods, planar well point selection and test well network deployment plans are designed. This can improve the efficiency of oil and water well testing without affecting production as much as possible, realize the deployment of planar and vertical logging methods and plans for heterogeneous reservoirs, provide effective test data for reservoir parameter inversion, and obtain good pressure buildup test data for well test interpretation of each typical well group. Comparative analysis can be carried out to obtain the planar and vertical reservoir parameters of the entire block and the connectivity relationship between each well.

[0048] Figure 1 FIG. 1 is a flow chart showing a method for determining well test information according to an exemplary embodiment. Figure 1 As shown, the method includes the following steps.

[0049] In step 101, the planar heterogeneity parameters of the reservoir to be tested are obtained.

[0050] In step 102, based on the planar heterogeneity parameter, at least one group of test wells for testing the reservoir is determined. The at least one group of test wells is a group of test wells for testing a target area where the reservoir is located.

[0051] In step 103, for each test well in the test well group, well logging data of the area where the test well is located is obtained, and based on the well logging data, the vertical heterogeneity parameter of the test well is determined.

[0052] In step 104, a testing method for the testing well is determined based on the longitudinal heterogeneity parameters of the testing well.

[0053] In step 105, the location of the at least one group of test wells and the test mode of each test well are determined as the well test information of the reservoir.

[0054] In some embodiments, determining a testing method for the test well based on the longitudinal heterogeneity parameter of the test well includes:

[0055] In response to the vertical heterogeneity parameter being greater than a preset threshold, determining that the test mode of the test well is a layered test or a general test;

[0060] In the deployed planar injection and production well network, at least one test well group is determined, and the at least one test well group is the test well group corresponding to the target location.

[0061] In some embodiments, determining at least one test well group in the deployed planar injection-production well pattern includes:

[0062] Based on the sand body distribution map, the main reservoir area in the area where the reservoir is located is determined through the correspondence between the reservoir development conditions and the plane physical properties of the sand body;

[0063] Through the correspondence between the injection-production relationship and the planar homogeneity, based on the deployed planar injection-production well network, the position of the test well group and the ratio of injection-production wells to production wells in the test well group are determined in the main reservoir area to obtain the test well group.

[0064] In some embodiments, determining the location of the at least one group of testing wells and the testing method of each testing well as the well testing information of the reservoir includes:

[0065] Performing pressure recovery logging on each test well in the test well group based on the test mode corresponding to the test well to obtain pressure recovery logging data;

[0066] An inter-well communication parameter is determined based on the well logging data, and the inter-well communication parameter is determined as the well testing information.

[0067] In the disclosed embodiment, by determining the testing method of each test well and the deployment position of the test well group, the well testing plan is determined, so that the oil and water well testing efficiency can be improved without affecting production as much as possible, and the planar and vertical logging methods and plan deployment of heterogeneous reservoirs can be realized, providing effective test data for reservoir parameter inversion, obtaining good pressure recovery test data, and reducing the impact on oil field production.

[0068] Figure 2 FIG. 1 is a flow chart showing a method for determining well test information according to an exemplary embodiment. Figure 2 As shown, the method includes the following steps.

[0069] In step 201 , the electronic device obtains planar heterogeneity parameters of a reservoir to be tested.

[0070] The planar heterogeneity parameters refer to the geometric shape, scale, and continuity of a reservoir sand body, as well as the planar variations in porosity and permeability within the sand body. These planar heterogeneity parameters are obtained by analyzing well test data obtained prior to this step. In this step, the electronic device inputs the planar heterogeneity parameters entered by the user.

[0071] In step 202, the electronic device determines at least one set of testing wells for testing the reservoir based on the planar heterogeneity parameter.

[0072] The at least one test well group is a test well group for testing the target area where the reservoir is located.

[0073] In this step, the electronic device determines the spatial distribution characteristics of the sand body based on the planar heterogeneity parameters of the current reservoir area, and deploys test wells in the main channel and non-main channel according to the development conditions of the reservoir, namely the structural characteristics, area, reserve abundance, main permeability direction, fracture development direction and reservoir anisotropy of the sand body, with reference to the sedimentary microfacies map. This step is achieved by the following steps (1)-(3), including:

[0074] (1) The electronic equipment analyzes the planar heterogeneity parameters of the reservoir to be tested and obtains the sand body distribution map of the area where the reservoir is located.

[0075] (2) The electronic device determines the target position of the reservoir on the sand body distribution map based on the sedimentary characteristics of the reservoir.

[0076] (3) The electronic device determines at least one test well group in the deployed planar injection and production well network, where the at least one test well group is the test well group corresponding to the target location.

[0077] In this step, the electronic device determines the main reservoir area of ​​the reservoir based on the sand body distribution map through the correspondence between the reservoir development conditions and the planar physical properties of the sand body; through the correspondence between the injection-production relationship and the planar homogeneity, based on the deployed planar injection-production well network, the position of the test well group and the ratio of injection-polymerization wells to production wells in the test well group are determined in the main reservoir area to obtain the group of test well groups.

[0078] For example, the sand body distribution map of the reservoir area is determined based on the plane heterogeneity parameters of the reservoir to be tested. Based on the sand body distribution map, the main oil-bearing area of ​​the reservoir is determined to be the main river channel area and the direction of sand body distribution. Therefore, the test well is set in the main river channel area. Figure 3 Common injection-production relationships include: one injection-one production, one injection-two production, two injections-one production, one injection-four production, and four injections-one production. The electronic device determines the ratio of injection-polymerization wells to production wells in the test well group based on the nature of the river channel and the direction of water flow, and obtains the test well group, including:

[0079] In response to the test well group being one injection and one production well group, the injection and polymerization wells are set in the main river channel in accordance with the water flow direction; and the production wells are set in the direction of the non-main river channel;

[0080] In response to the test well group being one injection and two production well groups, one production well is set in the main river channel in line with the water flow direction, the other production well is set in a non-main river channel perpendicular to the water flow direction, and based on the distance between the injection and production wells, the injection and polymerization well is set between the two production wells;

[0081] In response to the test well group being a two-injection and one-production well group, one injection and polymerization well is set in the main river channel in line with the water flow direction, the other injection and polymerization well is set in a non-main river channel perpendicular to the water flow direction, and the production well is set between the two production wells based on the distance between the injection and production wells;

[0082] In response to the fact that the test well group is a one-injection and four-production well group, two injection and polymerization wells are set on both sides of the main river channel. Following the direction of water flow, the other two injection and polymerization wells are set on both sides of the non-main river channel. Based on the distance between the injection and production wells, the injection and polymerization well is set between the two oil production wells.

[0083] In step 203, for each test well in the test well group, the electronic device obtains well logging data of the area where the test well is located, and determines the vertical heterogeneity parameter of the test well based on the well logging data.

[0084] The vertical heterogeneity parameter is the change in reservoir properties in the vertical direction, including the degree of vertical permeability difference, the grain size rhythm and permeability rhythm within the layer, and the distribution of discontinuous thin mud interlayers within the layer. The permeability distribution of the same reservoir includes uniform layers, positive rhythm oil layers, negative rhythm oil layers, and composite rhythm oil layers. Figure 4 , Figure 4 From left to right, the permeability distribution diagrams for simple positive rhythm reservoirs, complex positive rhythm reservoirs, uniform layers, inverse rhythm reservoirs, and composite rhythm reservoirs are shown. A uniform layer is a reservoir with little vertical permeability variation; a positive rhythm reservoir has high permeability at the bottom and gradually decreases upward; an inverse rhythm reservoir has low permeability at the bottom and gradually increases upward; and a composite rhythm reservoir is a combination of positive and inverse rhythm reservoirs.

[0085] In this step, the reservoir permeability distribution and vertical heterogeneity are determined based on the well logging data in the area where the test wells are located. For example, considering the sub-layer data from 20 test wells in a certain reservoir, four wells exhibit positive rhythm (20%), seven wells exhibit compound rhythm (35%), and nine wells exhibit negative rhythm (45%). This indicates that the vertical heterogeneity in the reservoir area is severe, indicating a high vertical heterogeneity parameter.

[0086] In step 204 , in response to the vertical heterogeneity parameter being greater than a preset threshold, the electronic device determines whether the test mode of the test well is a layered test or a general test.

[0087] Due to the serious longitudinal homogeneity, both layered testing and general testing were used, and then through comparative analysis, the reasonable testing method for different longitudinal homogeneities was determined.

[0088] When significant heterogeneity exists between reservoir layers, differences in physical properties can lead to imbalanced formation pressures and interlayer interference. This interlayer interference alters fluid flow patterns, affecting formation pressure, injection rate, seepage velocity, water content, oil-water front, and water breakthrough time within each layer. Pressure differences can also cause cross-flow between layers, severely impacting ultimate recovery.

[0089] Through layered testing, we obtain pressure change data for each sub-layer. Combined with the layered water absorption profile and single-well sub-layer data, we conduct well test analysis to determine the formation parameters of each sub-layer. By comparing the differences in physical properties between sub-layers, we analyze the factors that lead to inter-layer interference during reservoir development and adjust work systems to reduce the impact of inter-layer interference on recovery, thereby improving efficiency.

[0090] In step 205 , in response to the vertical heterogeneity parameter being less than the preset threshold, the electronic device determines that the test mode of the test well is a general test.

[0091] When the heterogeneous parameters of the test well are weak, a general test can be used to obtain the average formation parameters in the vertical direction of the entire reservoir area, ignoring the impact of interlayer interference, interlayer crossflow, etc. on single well production. The testing process is simple, shortens the construction period, reduces the well shutdown time, and improves economic benefits.

[0092] In step 206 , the electronic device determines the at least one group of test wells and the test mode of each test well as the well test information of the reservoir.

[0093] In this step, the electronic device performs pressure recovery logging on each test well in the test well group based on the test method corresponding to the test well to obtain pressure recovery logging data; determines the inter-well connectivity parameters based on the logging data, and determines the inter-well connectivity parameters as the well test information.

[0094] In the disclosed embodiment, by determining the testing method of each test well and the deployment position of the test well group, the well testing plan is determined, so that the oil and water well testing efficiency can be improved without affecting production as much as possible, and the planar and vertical logging methods and plan deployment of heterogeneous reservoirs can be realized, providing effective test data for reservoir parameter inversion, obtaining good pressure recovery test data, and reducing the impact on oil field production.

[0119] In some embodiments, the electronic device 600 further includes one or more sensors 610 , including but not limited to: an acceleration sensor 611 , a gyroscope sensor 612 , a pressure sensor 613 , a fingerprint sensor 614 , an optical sensor 615 , and a proximity sensor 616 .

[0120] The accelerometer 611 can detect the magnitude of acceleration along the three coordinate axes of the coordinate system established by the electronic device 600. For example, the accelerometer 611 can be used to detect the components of gravity acceleration along the three coordinate axes. The processor 601 can control the touchscreen display 605 to display the user interface in either a landscape or portrait view based on the gravity acceleration signal collected by the accelerometer 611. The accelerometer 611 can also be used to collect game or user motion data.

[0121] The gyroscope sensor 612 can detect the orientation and rotation angle of the electronic device 600. It can work in conjunction with the accelerometer 611 to collect the user's 3D movements of the electronic device 600. Based on the data collected by the gyroscope sensor 612, the processor 601 can implement the following functions: motion sensing (for example, changing the UI based on the user's tilt operation), image stabilization during shooting, game control, and inertial navigation.

[0122] The pressure sensor 613 can be located on the side frame of the electronic device 600 and / or below the touchscreen display 605. When the pressure sensor 613 is located on the side frame of the electronic device 600, it can detect the user's gripping signal of the electronic device 600. The processor 601 then performs left-hand or right-hand identification or shortcut operations based on the gripping signal collected by the pressure sensor 613. When the pressure sensor 613 is located below the touchscreen display 605, the processor 601 controls the operable controls on the UI interface based on the user's pressure operation on the touchscreen display 605. Operable controls include at least one of a button control, a scroll bar control, an icon control, and a menu control.

[0123] The fingerprint sensor 614 is used to collect the user's fingerprint. The processor 601 identifies the user based on the fingerprint collected by the fingerprint sensor 614, or alternatively, the fingerprint sensor 614 identifies the user based on the collected fingerprint. Upon determining that the user's identity is trusted, the processor 601 authorizes the user to perform relevant sensitive operations, including unlocking the screen, viewing encrypted information, downloading software, making payments, and changing settings. The fingerprint sensor 614 can be located on the front, back, or side of the electronic device 600. If the electronic device 600 has physical buttons or a manufacturer logo, the fingerprint sensor 614 can be integrated with the physical buttons or manufacturer logo.

[0124] The optical sensor 615 is used to detect ambient light intensity. In one embodiment, the processor 601 can control the display brightness of the touchscreen display 605 based on the ambient light intensity detected by the optical sensor 615. Specifically, when the ambient light intensity is high, the display brightness of the touchscreen display 605 is increased; when the ambient light intensity is low, the display brightness of the touchscreen display 605 is decreased. In another embodiment, the processor 601 can also dynamically adjust the shooting parameters of the camera assembly 606 based on the ambient light intensity detected by the optical sensor 615.

[0125] Proximity sensor 616, also known as a distance sensor, is typically located on the front panel of electronic device 600. Proximity sensor 616 is used to detect the distance between the user and the front of electronic device 600. In one embodiment, when proximity sensor 616 detects that the distance between the user and the front of electronic device 600 is gradually decreasing, processor 601 controls touchscreen display 605 to switch from the screen-on state to the screen-off state. When proximity sensor 616 detects that the distance between the user and the front of electronic device 600 is gradually increasing, processor 601 controls touchscreen display 605 to switch from the screen-off state to the screen-on state.
