Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic fracturing monitoring. Specifically, it relates to a method, device, and storage medium for generating a flaky fracturing fluid model sample. Background Art

Among them, the key to fracturing effect evaluation is fracturing monitoring technology, which is mainly used to reduce the risks and accidents of unconventional oil and gas resource fracturing development and guide the deployment of the next-stage fracturing operation tasks. Surface time-frequency electromagnetic fracturing monitoring, as a geophysical fracturing monitoring method that can quickly provide three-dimensional quantitative results at the fracturing operation site after microseismic. Microseismic targets the fracture network, while surface time-frequency electromagnetic method directly monitors the fracturing fluid and quickly provides the three-dimensional distribution and migration information of the fracturing fluid in space. The surface time-frequency electromagnetic fracturing monitoring imaging technology first completes model sample training before each fracturing stage and then quickly provides the fracturing fluid distribution information at the fracturing site.

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Referring to Figure 1 , an embodiment of the present invention provides a method for generating a sheet-shaped fracturing fluid model sample, and the method may include the following steps:

[0031] S102. Establish a target three-dimensional space;

[0032] S104. Perform grid processing on the target three-dimensional space to generate a three-dimensional space grid;

[0033] S106. Obtain the preset center point coordinates, preset quantity, preset extension direction, preset extension length threshold, preset thickness, and preset rotation angle threshold of the sheet-shaped fracturing fluid model sample to be generated;

[0034] S108. Linearly discretize and calculate the position coordinates of the preset quantity of sheet-shaped fracturing fluid model samples according to the preset center point coordinates, preset extension direction, preset extension length threshold, preset thickness, and preset rotation angle threshold;

[0035] S110. Input each position coordinate into the three-dimensional space grid respectively to generate the preset quantity of sheet-shaped fracturing fluid model samples.

[0036] According to the method for generating a sheet-shaped fracturing fluid model sample provided by the present invention, by setting multiple parameters such as the preset center point coordinates, preset quantity, preset extension direction, preset extension length threshold, preset thickness, and preset rotation angle threshold of the sheet-shaped fracturing fluid model sample to be generated, the irregular fracturing fluid model sample is quantitatively and rapidly parameterized and simulated, greatly enriching the random model samples of the fracturing fluid distribution with complex shapes. At the same time, the modeling difficulty of the sheet-shaped fracturing fluid model sample and the time and labor costs of the sheet-shaped fracturing fluid model sample with extension characteristics are minimized. It solves the technical problems in the related art that the characteristics of the sheet-shaped fracturing fluid model generated by the conventional parameterization method are too single and the description of the complex fracturing fluid model sample takes a long time.

[0037] At the same time, the present application adopts the method of the preset quantity and preset center point coordinates of the sheet-shaped fracturing fluid model sample to prevent the defect that the center position of the fracturing fluid model is too ideal and special. By setting the preset extension direction and preset extension length threshold of the sheet-shaped fracturing fluid model sample, the free walking, extension, and divergence range of the sheet-shaped fracturing fluid model sample on the plane can be corresponding, ensuring the representativeness of the sheet-shaped fracturing fluid model sample for the continuously expanding characteristics after the fracturing fluid is injected. However, it is difficult to achieve the diversity of simulation by the conventional method for generating regular fracturing fluid sheet models, and a large amount of labor and time costs are required to establish a fracturing fluid model with any shape. Moreover, the present application designs the thickness and conductivity parameters of the sheet-shaped fracturing fluid model sample and gives room for random variation to ensure the simulation effect of the sheet-shaped fracturing fluid model sample. And the method of using the preset rotation angle threshold in multiple directions is adopted to solve the spatial simulation problem of the arbitrarily inclined fracturing fluid model sample, and the arbitrarily free walking in space is used to simulate the inclined fracturing fluid model sample with different spreading ranges.

[0038] Furthermore, the present application uses the relationship between the multi-degree-of-freedom random parameters of the fracturing fluid model sample and the spatial linear position of the center point to calculate the position coordinates of the preset quantity of sheet-shaped fracturing fluid model samples. At the same time, each position coordinate is respectively input into the three-dimensional space grid, a sheet-shaped fracturing fluid model sample is generated and recorded, and finally the preset quantity of sheet-shaped fracturing fluid model samples can be generated. The preset quantity can be adjusted according to the actual sample quantity requirements. For example, if 100 fracturing fluid sheet model samples need to be generated, the input preset quantity is 100.

[0039] In the above embodiment, the preset center point coordinates include the X-direction coordinate parameter, Y-direction coordinate parameter, and Z-direction coordinate parameter.

[0040] In this embodiment, the present application uses the center point position range parameters with 3 degrees of freedom to set the center point position and spatial random range of the sheet-shaped fracturing fluid model sample, which can be arbitrarily selected according to actual needs to prevent the defect that the center position of the fracturing fluid model is too ideal and special.

[0041] In the above embodiments, the preset extension directions include eight directions, and each extension direction corresponds to a preset extension length threshold.

[0042] In this embodiment, the present application adopts an 8-degree-of-freedom parameterization method, and at the same time introduces a model extension length range based on the 8-degree-of-freedom parameters, so that the actual degree-of-freedom parameters on the fracturing fluid sheet are increased to 16, ensuring the universality, diversity, and generation efficiency of the sheet-shaped fracturing fluid model samples. For example, by default, the initial triaxial angles of the sheet-shaped fracturing fluid model samples are located in the YOZ plane. Set the preset extension length thresholds in 8 directions for the fracturing fluid model sheet, and set the preset extension length thresholds in 8 directions for the sheet-shaped fracturing fluid model samples as needed. The 8 directions are +X direction, -X direction, +Z direction, -Z direction, +Z+X direction, -Z-X direction, +Z-X direction, and -Z+X direction respectively. Among them, the preset extension directions and preset extension length thresholds can be manually set according to the actual situation.

[0043] In the above embodiments, the preset rotation angle thresholds include the X-direction preset rotation angle threshold, the Y-direction preset rotation angle threshold, and the Z-direction preset rotation angle threshold.

[0044] In this embodiment, the X-direction preset rotation angle threshold represents the angle range for the free rotation of the sheet-shaped fracturing fluid model sample around the X-axis direction where the center point is located. For example, the X-direction preset rotation angle threshold at the center position of the sheet-shaped fracturing fluid model sample is set to 0 degrees to 60 degrees. The Y-direction preset rotation angle threshold represents the angle range for the free rotation of the sheet-shaped fracturing fluid model sample around the Y-axis direction where the center point is located. For example, the Y-direction preset rotation angle threshold at the center position of the sheet-shaped fracturing fluid model sample is set to 0 degrees to 60 degrees. The Z-direction rotation angle represents the free rotation of the sheet-shaped fracturing fluid model sample around the Z-axis direction where the center point is located. For example, the Z-direction preset rotation angle threshold at the center position of the sheet-shaped fracturing fluid model sample is set to 0 degrees to 60 degrees. The present application adopts a multi-directional axis range parameterization method to solve the problem of spatial simulation of arbitrarily inclined fracturing fluid model samples, and adopts spatial arbitrary free walking to simulate the inclined fracturing fluid model samples with different spreading ranges. Among them, the preset rotation angle thresholds can be manually set according to the actual situation.

[0045] In the above embodiments, the steps of performing grid processing on the target three-dimensional space to generate a three-dimensional space grid specifically include: obtaining the preset maximum value, preset minimum value, and preset grid step size in the X, Y, and Z directions in the target three-dimensional space; calculating and generating a three-dimensional space grid according to the preset maximum value, preset minimum value, and preset grid step size.

[0046] In this embodiment, the range of the observation area of the fracturing fluid model sample to be generated is set according to actual needs, and the preset maximum values, preset minimum values in the three directions of X, Y, and Z are set. Then, the preset grid step sizes in the three directions of X, Y, and Z are set, and the meshing of the three-dimensional space is completed through coordinate linear calculation. Among them, the preset maximum values, preset minimum values, and preset grid step sizes can be manually set according to the actual situation.

[0047] In the above embodiment, the method for generating a flaky fracturing fluid model sample further includes: extracting the arrangement serial number index corresponding to the position coordinates in the three-dimensional space grid.

[0048] In this embodiment, the arrangement serial number index specifically refers to the serial number of the smallest grid unit that makes up the entire three-dimensional space grid. When the space within a certain three-dimensional range is meshed, the arrangement order of each smallest cell generally needs to be determined in advance to facilitate subsequent search or query.

[0049] In the above embodiment, the method for generating a flaky fracturing fluid model sample further includes: obtaining the preset conductivity of the fracturing fluid model sample; inputting the preset conductivity into the three-dimensional space grid.

[0050] In this embodiment, conductivity is a commonly used physical property parameter of an object. The fracturing fluid has conductivity properties, and it can generally be measured by a conductivity monitoring instrument. In the three-dimensional grid model of the present invention, the grid cells corresponding to the positions where the fracturing fluid model exists will be filled with the given fracturing fluid conductivity values.

[0051] An embodiment of another aspect of the present invention provides a method for generating a flaky fracturing fluid model sample, and the method may include the following steps:

[0052] Step 1: Meshing of the three-dimensional space. The range of the observation area is set according to actual needs, and the maximum and minimum value ranges in the three directions of X, Y, and Z are set. Then, the grid step sizes in the three directions of X, Y, and Z are set, and the meshing of the three-dimensional space is completed through coordinate linear calculation.

[0053] Step 2: Parameterization of the number of flaky fracturing fluid models and the range of the center point position. In the established three-dimensional space grid, 1 parameter for the number of flaky fracturing fluid models and 3 parameters for the range of the center point position with 3 degrees of freedom are introduced. 1 parameter for the number of flaky fracturing fluid models is used to generate a specified number of flaky fracturing fluid models, which can be adjusted according to the actual sample quantity requirements. The 3 parameters for the range of the center point position with 3 degrees of freedom are used to set the center point position and the spatial random range of the flaky fracturing fluid model, and can be arbitrarily selected according to actual needs.

[0054] In this step, to prevent the defect that the center position of the fracturing fluid model is too ideal and special, the present invention adopts a method of parameterizing the number of fracturing fluid sheet models and the range of the center point position to solve the above problems.

[0055] Step 3: Parameterize the extension length range of the eight degrees of freedom of the fracturing fluid model sheet plane. By default, the initial angles of the three axes of the fracturing fluid sheet model are located in the YOZ plane. Set the extension length parameters in 8 directions for the fracturing fluid model sheet, and set the extension length ranges in 8 directions for the fracturing fluid sheet model as needed. The 8 directions are the +X direction, -X direction, +Z direction, -Z direction, +Z+X direction, -Z-X direction, +Z-X direction, and -Z+X direction respectively. The parameterization of the extension length range of the eight degrees of freedom can correspond to the free walking, extension, and divergence ranges of the fracturing fluid sheet model on the plane. Ensure the representativeness of the fracturing fluid sheet model for the continuously expanding characteristics after the injection of the fracturing fluid.

[0056] In this step, the present invention adopts an innovative method of parameterizing 8 degrees of freedom, and at the same time introduces the model extension length range based on the 8-degree-of-freedom parameters, so that the actual degree-of-freedom parameters on the fracturing fluid sheet are increased to 16, ensuring the universality, diversity, and generation efficiency of the fracturing fluid sheet model. The conventional method for generating regular fracturing fluid sheet models is difficult to achieve simulation diversity, and it requires a large amount of labor and time costs to establish fracturing fluid sheet models of arbitrary shapes.

[0057] Step 4: Parameterize the thickness and conductivity range of the fracturing fluid sheet model. Introduce 1 degree of freedom for the thickness parameter of the fracturing fluid sheet model and 1 conductivity parameter for the fracturing fluid sheet model. The range of variation of the 1 degree of freedom for the thickness parameter of the fracturing fluid sheet model is set as needed, that is, the extension range in the Y direction. The 1 conductivity parameter of the fracturing fluid sheet model can be set according to the conductivity measurement results.

[0058] In this step, the present invention designs the thickness and conductivity parameters of the fracturing fluid sheet model and gives room for random variation to ensure the simulation effect of the fracturing fluid sheet model.

[0059] Step 5: Parameterize the range of the three azimuth rotation angles of the fracturing fluid sheet model. They are the rotation angle in the X direction, the rotation angle in the Y direction, and the rotation angle in the Z direction. Among them, the rotation angle in the X direction represents the free rotation of the fracturing fluid sheet model around the X axis where the center point is located; the rotation angle in the Y direction represents the free rotation of the fracturing fluid sheet model around the Y axis where the center point is located; the rotation angle in the Z direction represents the free rotation of the fracturing fluid sheet model around the Z axis where the center point is located. The fracturing fluid sheet model in the initial position in Step 4 makes arbitrary changes in 6 degrees of freedom according to the parameter range of the three-axis rotation angles, which are the maximum free rotation angle θ of the fracturing fluid sheet model around the X axis where the center point is located x_max and the minimum free rotation angle θ of the fracturing fluid sheet model around the X axis where the center point is locatedx_min 、The maximum free rotation angle θ in the Y-axis direction where the center point is located y_max 、The minimum free rotation angle θ in the Y-axis direction where the center point is located y_min 、The maximum free rotation angle θ in the Z-axis direction where the center point is located z_max 、The minimum free rotation angle θ in the Z-axis direction where the center point is located z_min 。

[0060] In this step, the present invention uses a multi-directional axis range parameterization method to solve the spatial simulation problem of an arbitrarily inclined fracturing fluid sheet model, and uses a spatial arbitrary free walk to simulate inclined fracturing fluid sheet models with different spread ranges.

[0061] Step 6: Calculate the parameterized position coordinates of the fracturing fluid sheet model and discretely fill them into the three-dimensional grid space. According to the center point coordinates of the fracturing fluid sheet model, the extension length range parameters of eight degrees of freedom in the plane, the thickness parameter, and the three-orientation rotation angle range parameters, linearly discretely calculate the position coordinates of the center points of each grid of the fracturing fluid sheet model, and extract the arrangement serial number index corresponding in the three-dimensional grid space under the coordinates. Finally, fill the conductivity attribute value at the corresponding grid position.

[0062] In this step, the present invention uses the relationship between the multi-degree-of-freedom random parameters of the fracturing fluid sheet model and the spatial linear position of the center point, extracts the position index and attributes of the fracturing fluid sheet model in the three-dimensional grid space, and performs spatial replacement. Thus, the richness of the characteristics of the fracturing fluid sheet model is ensured.

[0063] The present invention uses a parameterization method for a sheet-shaped fracturing fluid sheet model to quantitatively and quickly parameterize and simulate an irregular fracturing fluid sheet model, greatly enriching the random model samples of the fracturing fluid distribution with complex shapes. At the same time, it minimizes the modeling difficulty of the fracturing fluid sheet model and the time and labor costs of the fracturing fluid sheet model samples with extended characteristics.

[0064] In a specific embodiment, the method for generating a sheet-shaped fracturing fluid model sample includes the following steps:

[0065] 1) Perform a three-dimensional space grid within the observation area where X ranges from 0 m to 100 m, Y ranges from 0 m to 100 m, and Z ranges from -100 m to 0 m. The step size in the X direction is 1 m, the step size in the Y direction is 1 m, and the step size in the Z direction is 1 m. Calculate and generate the node coordinates of the three-dimensional space grid.

[0066] 2) Select the number of fracturing fluid sheet models to be 100, and the X coordinate parameter of the center point position is 50 m, the Y coordinate parameter is 50 m, and the Z coordinate parameter is -50 m.

[0067] 3) It is estimated that the maximum extension length of the fracturing fluid sheet model in each direction is 30 meters. The +X direction range of the eight-degree-of-freedom direction is set from 0 meters to 30 meters; the -X direction range is set from 0 meters to 30 meters; the +Z direction range is set from 0 meters to 30 meters; the -Z direction range is set from 0 meters to 30 meters; the +Z+X direction range is set from 0 meters to 30 meters; the -Z-X direction range is set from 0 meters to 30 meters; the +Z-X direction range is set from 0 meters to 30 meters; the -Z+X direction range is set from 0 meters to 30 meters.

[0068] 4) The thickness of the fracturing fluid sheet model can be arbitrarily given and set within a range. To characterize the fracturing fluid sheet model, the thickness parameter is selected as 1 meter and the conductivity parameter is set as 100 S / m in this demonstration.

[0069] 5) Assume that the maximum rotation angle range of the fracturing fluid sheet model in the X, Y, and Z directions is 60 degrees. The X-axis rotation angle range of the center position of the fracturing fluid sheet model is set from 0 degrees to 60 degrees, the Y-axis rotation angle range is set from 0 degrees to 60 degrees, and the Z-axis rotation angle range is set from 0 degrees to 60 degrees.

[0070] 6) According to the center point coordinates of the fracturing fluid sheet model, the extension length range parameters of the eight degrees of freedom in the plane, the thickness parameter, and the three azimuth rotation angle range parameters in steps 1) to 5), linearly discretize and calculate the position coordinates of the center points of each grid of the fracturing fluid sheet model, and extract the arrangement serial number index corresponding in the three-dimensional grid space under the coordinates. Fill the conductivity of 100 S / m at the corresponding grid position.

[0071] Through the above steps, the rapid generation of the fracturing fluid sheet model is realized, and a representative complex-shaped fracturing fluid sheet model sample dataset can be generated indoors in advance. It solves the technical problems that the characteristics of the fracturing fluid model generated by the conventional parameterization method are too single and the description of the complex fracturing fluid sheet model takes a long time. As Figure 2 shown, Figure 2 the generation results of some sheet-shaped fracturing fluid model samples are shown, which also proves the feasibility of the method of the present invention to enrich the arbitrary distribution form of the fracturing fluid sheet model.

[0072] The present invention provides a parameterization method for a random fracturing fluid sheet model in artificial intelligence three-dimensional rapid imaging in surface time-frequency electromagnetic method fracturing monitoring to quantitatively and rapidly parameterize the shape of a single-stage multi-cluster irregular fracturing fluid. The purpose is to quickly obtain a representative random model of the complex-shaped fracturing fluid distribution with a small model space consumption and generate a large number of training samples.
