These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application.

[0053] Conglomerate reservoirs are a type of oil and gas reservoir. Some of the reservoirs in conglomerate reservoirs need to be hydraulically fracturing before they can be exploited. Generally, it is necessary to evaluate the mechanical properties of the conglomerate reservoir, specifically the microscopic strength of the conglomerate reservoir, in order to formulate relevant fracturing schemes.

[0054] In addition to fracturing scenarios, tasks such as rock breaking and wellbore stability analysis also require understanding the microstructure of conglomerate.

[0055] The microstructure strength of conglomerate reservoirs is affected not only by the gravel grains and conglomerate matrix, but also by the cementation strength between the gravel and the matrix.

[0056] High-strength, large-sized gravel can effectively inhibit cracks from penetrating the gravel, thereby strengthening the overall tensile strength of the conglomerate.

[0057] Therefore, when fracturing conglomerate reservoirs, it is necessary to comprehensively consider the effects of conglomerate gravel, conglomerate matrix, and cementation strength between gravel and matrix in order to better understand the microstructure of the conglomerate reservoir and thus achieve a more effective fracturing scheme.

[0058] In existing technologies, methods for determining the microstructure strength of conglomerate reservoirs require the introduction of a large amount of complex parameter information, which is costly and time-consuming, and difficult to apply in mining sites.

[0059] Therefore, determining the microstructure strength of conglomerate reservoirs presents challenges due to operational difficulties and low efficiency.

[0060] The method, apparatus, equipment, and medium for determining the microstructure strength of conglomerate reservoirs provided in this application obtain fracturing data of the conglomerate samples by applying pressure to them. The conglomerate samples represent samples collected from the conglomerate reservoir, and multiple conglomerate samples are available. The fracturing data represents the displacement of pressure when applied to the conglomerate samples, and the pressure is used to generate fractures in the conglomerate samples. The area information of the fractures in the conglomerate samples is then determined, so that the microstructure strength information of the conglomerate reservoir can be determined based on the fracturing data and area information of each conglomerate sample. The area information represents the area of ​​the fracture cross-section, and the microstructure strength information includes at least one of gravel strength, matrix strength, and cementation strength. The method for determining the microstructure strength of conglomerate reservoirs provided in this application only requires applying pressure to the conglomerate samples to determine the area information of the fractures in the conglomerate samples, thus enabling the determination of the microstructure strength information of the conglomerate reservoir based on the fracturing data and area information of each conglomerate sample, without introducing a large amount of complex parameter information to determine the microstructure strength of the conglomerate reservoir. The method for determining the microstructure of conglomerate reservoirs provided in this application reduces the operational difficulty of determining the microstructure of conglomerate reservoirs and improves the efficiency of determining the microstructure of conglomerate reservoirs.

[0061] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0062] Figure 1 This application provides a flowchart illustrating a method for determining the microstructure strength of conglomerate reservoirs. The method can be executed by a server, host, or other device, such as... Figure 1 As shown, the method may include:

[0063] S101. Fracturing data of conglomerate samples are obtained by applying pressure to the conglomerate samples; wherein, the conglomerate samples represent samples collected from the conglomerate reservoir, and there are multiple conglomerate samples; the fracturing data represent the displacement of pressure when pressure is applied to the conglomerate samples, and the pressure is used to generate fractures in the conglomerate samples.

[0064] Among them, conglomerate samples can refer to samples collected by staff from conglomerate reservoirs, which can be composed of gravel and matrix filling the gaps between the gravel.

[0065] There are multiple conglomerate samples. It can be understood that each of these multiple conglomerate samples has the same volume, meaning that the length, width, and height of each sample are identical. Alternatively, each of the multiple conglomerate samples has the same front view, top view, and side view. Figure 1 To.

[0066] In one possible implementation, multiple conglomerate samples can be collected from different locations within the conglomerate reservoir. It is understood that the gravel content in these multiple conglomerate samples will vary.

[0067] By applying pressure to a conglomerate sample, the pressure causes the conglomerate sample to crack. It can be understood that the crack can divide an original conglomerate sample into two smaller conglomerate samples. That is, applying pressure to a conglomerate sample can cause the conglomerate sample to crack.

[0068] During the process of applying pressure to a conglomerate sample, the pressure does work on the conglomerate sample to generate cracks. Specifically, the displacement of the pressure on the conglomerate sample can refer to the fracturing data of the conglomerate sample.

[0069] In one possible implementation, to better describe the scenario of applying pressure to a conglomerate sample, Figure 2 This application provides a schematic diagram of a scenario where pressure is applied to a conglomerate sample. Figure 1 ,like Figure 2As shown, when viewed from the front, the front view of the conglomerate sample can be a semicircle, meaning the cross-section of the conglomerate sample is a semicircle.

[0070] It is understandable that the top view of a conglomerate sample can be rectangular, and the side view of a conglomerate sample can also be rectangular.

[0071] Looking at the conglomerate sample from the front, it can be seen that the conglomerate sample is fixed by three support points, all of which are circular. Two lower support points are set at the bottom of the conglomerate sample to support it, and one upper support point is set at the top of the conglomerate sample to apply pressure to it.

[0072] Viewing the conglomerate sample from a three-dimensional perspective, it can be understood that the sample is fixed by three support rods, all of which have circular cross-sectional areas, serving as the support points from a frontal view. Correspondingly, two lower support rods are placed at the bottom of the sample to support it, and one upper support rod is placed at the top to apply pressure. The length of each support rod is greater than or equal to the thickness of the conglomerate sample; the length of the support rod can be understood as the distance between its two ends.

[0073] In one possible implementation, the distance between the two lower support rods can be represented by s, the radius of the semicircular cross-section of the conglomerate sample can be represented by R, and the distance s between the two lower support rods satisfies:

[0074] ;

[0075] For example, the diameter of the cross-sectional circles of the two lower support rods can both be 10 mm, and the diameter of the semi-circular cross-section of the conglomerate sample can be 200 mm.

[0076] In one possible implementation, the diameter of the support rod satisfies the following condition:

[0077] ;

[0078] in, Indicates the diameter of the support rod. This indicates the diameter of the semicircular cross-section of the conglomerate sample.

[0079] In one alternative implementation, a notch is provided at the bottom of the conglomerate sample. When viewed from the front, the notch of the conglomerate sample is rectangular. When viewed from a three-dimensional perspective, the thickness of the conglomerate sample is the same as the thickness of the notch.

[0080] In one possible implementation, the height of the notch can be represented by 'a', the radius of the semicircular cross-section of the conglomerate sample can be represented by R, and the height of the notch 'a' satisfies:

[0081] ;

[0082] For example, a thin cutting blade with a thickness of 1.5 ± 0.2 mm or a fine wire saw impregnated with diamond can be used to cut the conglomerate sample in a direction consistent with the thickness of the conglomerate sample, passing through the center of the semicircle of the conglomerate sample to create a gap in the conglomerate sample.

[0083] By setting a notch, the cracks generated in the conglomerate sample when pressure is applied to the conglomerate sample by the upper support rod can connect the upper support point to the notch, ensuring the stability of the crack surface and the consistency of the cracks generated by multiple conglomerate samples, thereby ensuring the consistency of the fracturing data obtained from multiple conglomerate samples.

[0084] In one alternative implementation, Figure 3 This application provides a schematic diagram of a scenario where pressure is applied to a conglomerate sample. Figure 2 ,like Figure 3 As shown, conglomerate samples can also be cuboids.

[0085] Looking at the conglomerate sample from the front, it can be seen that the conglomerate sample is fixed by three support points, all of which are circular. Two lower support points are set at the bottom of the conglomerate sample to support it, and one upper support point is set at the top of the conglomerate sample to apply pressure to it.

[0086] Viewing the conglomerate sample from a three-dimensional perspective, it can be understood that the sample is fixed by three support rods, all of which have circular cross-sectional areas, serving as the support points from a frontal view. Correspondingly, two lower support rods are placed at the bottom of the sample to support it, and one upper support rod is placed at the top to apply pressure. The length of each support rod is greater than or equal to the thickness of the conglomerate sample; the length of the support rod can be understood as the distance between its two ends.

[0087] For example, the distance between the two lower support rods can be represented by s.

[0088] In one alternative implementation, a notch is provided at the bottom of the conglomerate sample. When viewed from the front, the notch of the conglomerate sample is rectangular. When viewed from a three-dimensional perspective, the thickness of the conglomerate sample is the same as the thickness of the conglomerate sample.

[0089] For example, the height of the gap can be represented by 'a'.

[0090] It should be noted that this application only exemplifies the shapes of conglomerate samples as semi-cylindrical and cuboid. In real-world scenarios, conglomerate samples can also be other shapes. The front view of the conglomerate sample is symmetrical. No specific shape of the conglomerate sample is limited here.

[0091] In one optional implementation, obtaining fracturing data from multiple conglomerate samples may include:

[0092] For each conglomerate sample, pressure is applied at a preset location on the conglomerate sample to obtain the displacement information corresponding to the pressure; the correlation between the pressure and the displacement information is determined as the fracturing data of the conglomerate sample.

[0093] The preset location of the conglomerate sample can refer to the location where pressure is applied to the conglomerate sample.

[0094] For example, the pressure can be applied to the top of the conglomerate sample, and this location is on the line of symmetry of the front view of the conglomerate sample.

[0095] Specifically, the pressure applied to the conglomerate sample was vertically downward.

[0096] In one possible implementation, a pre-set press can be used to apply a load at a fixed loading rate to apply pressure at a preset location on the conglomerate sample, thereby obtaining displacement information corresponding to the pressure.

[0097] The displacement information corresponding to pressure can refer to the scale information of the downward movement of pressure. It can be understood that there is a correlation between pressure and the displacement information corresponding to pressure, that is, the correlation between pressure and displacement information is the fracturing data of conglomerate samples.

[0098] For example, at a certain moment, the pressure is 625 Pa, and the displacement information corresponding to the pressure is 0.15 mm.

[0099] By determining the fracturing data of conglomerate samples, the work done by pressure on the conglomerate samples can be determined, providing data support for the subsequent determination of the microstructure strength information of conglomerate reservoirs. Moreover, the fracturing data of each conglomerate sample can be determined, ensuring the consistency of the determination of the microstructure strength information of conglomerate reservoirs.

[0100] S102. Determine the area information of the fractures in the conglomerate sample; where the area information represents the area of ​​the fracture cross section.

[0101] Among them, the area information of the crack can refer to the surface area information of the crack when viewed from the side.

[0102] It is understandable that when viewed from the side, the crack surface can show the area of ​​the conglomerate sample after it has been divided by the crack.

[0103] In one optional embodiment, the conglomerate sample includes gravel and matrix, and the area information includes the area information of the gravel and the area information of the matrix; wherein, the area information of the gravel represents the area of ​​the gravel visible in the fracture cross section, and the area information of the matrix represents the area of ​​the matrix visible in the fracture cross section.

[0104] Among them, gravel can refer to rock fragments in conglomerate samples, and the diameter of gravel can be greater than 2 mm.

[0105] The matrix can refer to the fine mechanical inclusions that fill the spaces between the gravels; that is, the matrix can refer to non-chemically precipitated particles with a particle size of less than 0.03 mm. For example, the matrix can be silt or sand-grade particles.

[0106] It is understandable that determining the area information of fractures in conglomerate samples can include determining the area information of gravel and matrix in the fracture cross section.

[0107] Determining the area of ​​fractures in conglomerate samples can include:

[0108] The area information of the matrix in the conglomerate sample is obtained through a preset image acquisition device; if the gravel is divided by cracks, the area information of the gravel in the conglomerate sample is obtained through a preset image acquisition device.

[0109] The preset image acquisition device may include, but is not limited to, a camera. It can be understood that by acquiring cross-sectional images of cracks in a conglomerate sample, the area information of the gravel and matrix on the crack surface of the conglomerate sample can be determined.

[0110] If the gravel is divided by cracks, it can be understood that the area information of the gravel is closer to a flat circle. The area information of the gravel divided by cracks can be directly obtained by taking pictures through a preset image acquisition device.

[0111] In one optional implementation, if the gravel is not divided by cracks, the spherical projection area of ​​the gravel in the conglomerate sample is obtained by a preset image acquisition device; and the area information of the gravel in the conglomerate sample is determined based on the spherical projection area.

[0112] If the gravel is not divided by cracks, it can be understood that the area information of the gravel is closer to the surface area of ​​the part of the sphere. In this case, the area information of the gravel can be called the peeling area of ​​the gravel.

[0113] Using a pre-set image acquisition device, the spherical projection area of ​​the unfractured gravel below the fracture surface in a conglomerate sample can be directly captured.

[0114] It is understandable that the area information of each gravel in a conglomerate sample can be determined based on the spherical projection area of ​​each gravel that is not divided by cracks.

[0115] For example, the area information of the gravel can be calculated based on the radius of the circle of the spherical projection of the gravel that is not divided by the crack, and the distance between the vertex of the sphere and the crack surface, i.e., the height of the spherical cap.

[0116] To better describe the area information of fractures in conglomerate samples, Figure 4 A schematic diagram illustrating the area information of fractures in the conglomerate sample provided in this application, as shown below. Figure 4 As shown, from the perspective of viewing the crack surface directly, there are multiple gravels, and the matrix surrounds the gravels. Figure 4 Solid circles in the diagram represent gravel separated by cracks, while dashed circles represent gravel not separated by cracks.

[0117] Figure 5 A schematic diagram of gravel divided by cracks provided in this application, as shown below. Figure 5 As shown, from the perspective of viewing the conglomerate sample from the front, or from the perspective of viewing the fracture surface from the side, the gravel is divided by the fracture, and the area information of the gravel divided by the fracture can be obtained directly by taking pictures.

[0118] Figure 6 A schematic diagram of unfractured gravel provided in this application, as shown below. Figure 6 As shown, from the perspective of viewing the conglomerate sample from the front, or from the perspective of viewing the fracture surface from the side, the gravel is not divided by the fracture, and the spherical projection area of ​​the gravel that is not divided by the fracture can be obtained directly by taking pictures.

[0119] In one alternative implementation, if the gravel is not divided by cracks, the area information of the gravel in the conglomerate sample can be characterized as follows:

[0120] ;

[0121] in, Characterize the area information of gravel in conglomerate samples. Characterizes the spherical projected area of ​​gravel in a conglomerate sample.

[0122] Among them, we obtained The reasoning can be done as follows:

[0123] Combination Figure 6 As shown, the radius of the circle of the spherical projection of a gravel not divided by a crack can be represented by r, the distance between the vertex of the sphere and the crack surface, i.e. the height of the spherical cap, can be represented by h, and the radius of the gravel can be represented by R.

[0124] The gravel is vertically cut into n parts along its radius, where n is close to infinity. The area of ​​the circle at the i-th part is... It can satisfy:

[0125] ;

[0126] Accordingly, the average area of ​​the circles corresponding to the n positions is obtained by averaging the n circles. It can satisfy:

[0127] ;

[0128] Furthermore, it can be determined that, for the circles corresponding to n positions, the average radius r of the circle can satisfy:

[0129] ;

[0130] Furthermore, it can be determined that the average spherical cap height h of the unfractured gravel can satisfy:

[0131] ;

[0132] Furthermore, the average spherical area of ​​the unfractured gravel, or the area information of the gravel in the conglomerate sample, can be determined. It can satisfy:

[0133] ;

[0134] By the average spherical area of ​​the gravel not divided by cracks The average area of ​​the circles corresponding to the n positions By dividing, we can see that and The relationship satisfies:

[0135] ;

[0136] Therefore, it can be concluded that The conclusion, among which, Characterize the area information of gravel in conglomerate samples. Characterizes the spherical projected area of ​​gravel in a conglomerate sample.

[0137] It is understandable that if the gravel is not divided by cracks, the spherical projection area of ​​the undivided gravel can be obtained directly by taking pictures. Then, based on the spherical projection area of ​​the undivided gravel, the area information of the undivided gravel in the conglomerate sample can be determined.

[0138] By using This formula determines the area information of pebbles not divided by cracks in a conglomerate sample. It only requires taking a picture to obtain the spherical projection area of ​​the pebbles not divided by cracks, without any other complicated operations, thus improving the efficiency of determining the area information of cracks in conglomerate samples.

[0139] S103. Based on the fracturing data and area information of each conglomerate sample, determine the microstructure strength information of the conglomerate reservoir; wherein, the microstructure strength information includes at least one of gravel strength, matrix strength, and cementation surface strength.

[0140] Among them, the microscopic strength information of conglomerate reservoirs can characterize the mechanical properties of conglomerate reservoirs at the microscale.

[0141] Specifically, the microstructure strength information of conglomerate reservoirs may include at least one of gravel strength, matrix strength, and cementation strength.

[0142] Among them, gravel strength can refer to the mechanical strength of gravel. It can be understood that the higher the strength of gravel, the more effectively it can prevent the penetration of cracks, thereby enhancing the overall strength of the conglomerate reservoir, so that the conglomerate reservoir can withstand greater external forces without being destroyed.

[0143] Matrix strength can refer to the mechanical strength of the matrix. It can be understood that the strength of the matrix is ​​usually lower than that of the gravel. Therefore, when a conglomerate reservoir is subjected to external forces, fractures usually preferentially penetrate the matrix rather than the gravel.

[0144] The cemented surface can refer to the interface between the gravel and the matrix. It can be understood that the gravel and the matrix are bonded together by a cementing material, which can be siliceous, calcareous, clayey, etc.

[0145] Cemented surface strength can refer to the mechanical strength of the cemented surface. It can be understood that in a low-strength cemented surface, cracks are more likely to propagate along the cemented surface rather than through the gravel or matrix.

[0146] It is understood that the microstructure strength information of conglomerate reservoirs includes at least one of gravel strength, matrix strength, and cementation strength, which reflects the ease with which fractures propagate through the gravel, matrix, or cementation surface under external forces.

[0147] In one alternative implementation, step S103 may include:

[0148] Based on the fracturing data of the conglomerate samples, the work data corresponding to the conglomerate samples is determined; whereby the work data characterizes the mechanical work generated by the pressure when the conglomerate sample is fracturing; based on the work data of each conglomerate sample and the area information of each conglomerate sample, the microstructure strength information of the conglomerate reservoir is determined.

[0149] The work data corresponding to the conglomerate sample can refer to applying pressure to the conglomerate sample, which performs mechanical work on the conglomerate sample until the conglomerate sample is crushed and cracks are generated. The starting point of the crack is at a predetermined position in the conglomerate sample, and the ending point of the crack is at the gap in the conglomerate sample.

[0150] It is understandable that the work data corresponding to the conglomerate sample can be determined based on the fracturing data of the conglomerate sample, that is, the displacement of the pressure when pressure is applied to the conglomerate sample.

[0151] In one alternative implementation, the work data corresponding to the conglomerate sample can be determined by plotting the relationship curve between pressure and displacement information in the fracturing data of the conglomerate sample.

[0152] For example, Figure 7 A schematic diagram of the relationship between pressure and displacement information in the fracturing data of the conglomerate sample provided in this application is shown below. Figure 7 As shown, the vertical axis represents the pressure applied to the conglomerate sample, and the value of the pressure (abbreviated as force) is shown. The unit of force can be Newton, represented by N. The horizontal axis represents the displacement of the force as pressure is applied to the conglomerate sample, and the unit of displacement can be millimeters, represented by mm.

[0153] from Figure 7 It can be seen that by plotting the relationship curve between pressure and displacement information in the fracturing data of conglomerate samples, the area enclosed by pressure and displacement can be the mechanical work generated by pressure when the conglomerate sample is fracturing, which is the work data corresponding to the conglomerate sample.

[0154] For example, the work data corresponding to the conglomerate sample is 8.6 joules.

[0155] It is understandable that by using the work data and area information of each conglomerate sample, the microstructure strength information of the conglomerate reservoir can be determined simply and quickly. Each conglomerate sample can be at least three conglomerate samples, and each conglomerate sample is located in a different position in the conglomerate reservoir, that is, the gravel content of each conglomerate sample is different.

[0156] In one alternative implementation, the conglomerate sample may include a first sample, a second sample, and a third sample, and the mesoscopic intensity information may be characterized as follows:

[0157] ;

[0158] in, The sum of the area information of the gravel segmented by the crack in the first sample. The sum of the area information of the gravel segmented by the crack in the second sample. The sum of area information representing the gravel segmented by cracks in the third sample. Characterize the area information of the heterogroups in the first sample. The area information of the heterogroups in the second sample is used to characterize the heterogroups. Characterize the area information of the heterogroups in the third sample. The sum of area information representing the gravel not divided by cracks in the first sample. The sum of area information representing the gravel not divided by cracks in the second sample. The sum of area information representing the gravel not divided by cracks in the third sample. Characterizing gravel strength in microscopic strength information, Characterizing the strength of the cemented surface in microscopic strength information, Characterizing matrix strength in microstructure strength information, The work data characterizing the first sample The work data characterizing the second sample The work data characterizing the third sample.

[0159] For example, the gravel content in the first sample was 23.4%, the gravel content in the second sample was 20.7%, and the gravel content in the third sample was 41.1%.

[0160] The area information obtained through a preset image acquisition device may include:

[0161] The sum of the area information of the gravel divided by the crack in the first sample This could be 237.89 square millimeters, the sum of the area information of the gravel divided by the crack in the second sample. This could be 848.15 square millimeters, the sum of the area information of the gravel divided by the crack in the third sample. It can be 174.5 square millimeters;

[0162] Area information of heteropolymers in the first sample The area information of the heterogroup in the second sample can be 1.11 square millimeters. The area information of the heterobase in the third sample can be 1.08 square millimeters. It can be 0.83 square millimeters;

[0163] The sum of the area information of the gravel not divided by cracks in the first sample This could be 129.27 square millimeters, the sum of the area information of the gravel not divided by cracks in the second sample. This can be 250.94 square millimeters, the sum of the area information of the gravel not divided by cracks in the third sample. It can be 516.28 square millimeters;

[0164] Work data of the first sample The power data for the second sample can be 8.6455 joules. The power data for the third sample can be 5.3879 joules. It can be 6.8808 joules.

[0165] It is understood that, given the sum of the area information of gravel divided by cracks in each sample, the area information of the matrix in each sample, the sum of the area information of gravel not divided by cracks in each sample, and the work data of each sample, the microstructure strength information can be determined. The microstructure strength information can include gravel strength, cemented surface strength, and matrix strength.

[0166] For example, by solving the above formula, the gravel strength in the mesoscopic strength information can be obtained. The strength can be 21615.96 Pa, which is the bonding strength in the microscopic strength information. The value can be 1154.85 Pa, and the matrix strength in the micro-strength information can be... It can be 3014.36 Pa.

[0167] It should be noted that if the strength information includes other strength information, the method for determining the other strength information is the same as the method for determining the gravel strength, cemented surface strength, and matrix strength, and will not be repeated here.

[0168] This application provides a method for determining the microstructure strength of conglomerate reservoirs. This method only requires applying pressure to the conglomerate sample to determine the area of ​​fractures within the sample. This allows for the determination of the microstructure strength of the conglomerate reservoir based on the fracturing data and area information of each sample, without requiring the introduction of a large amount of complex parameter information. The method provided in this application reduces the operational difficulty of determining the microstructure strength of conglomerate reservoirs and improves the efficiency of this determination.
