On the contrary, these embodiments are provided to make the disclosure more thorough and complete, and to fully convey the scope of the disclosure to those skilled in the art.

[0026] In order to solve the above technical problems, the embodiment of the application provides a hydraulic parameter optimization method based on a digital-analog test, which can be executed by a computer, as shown in the figure, the method can include the following steps: Figure 1

[0027] S10, obtaining the pressure distribution image of the physical model under the action of the high-pressure pulse jet flow based on the pressure sensor array. ​

[0028] wherein the high-voltage pulse refers to a pulse voltage in the range of several thousand volts to several ten thousand volts, and a pulse width in the range of microseconds or milliseconds. A pressure sensor is a device or apparatus that can sense a pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule. A pressure sensor generally consists of a pressure-sensitive element and a signal processing unit. A pressure sensor array is a group of pressure sensors, usually deployed in a certain geometric pattern, for collecting and processing pressure signals. The advantage of using a sensor array instead of a single sensor is that the array adds a new dimension to the observation, which helps to estimate more parameters and improve the estimation performance.

[0029] In an exemplary embodiment, after step S10, the following steps can also be included:

[0030] S61, presetting the positions and numbers of the pressure sensors in the pressure sensor array for subsequent data analysis and result verification.

[0031] S20, acquiring the pressure change and propagation path of the high-voltage pulse jet.

[0035] S30, analyzing the pressure distribution image to obtain the penetration of the high-voltage pulse jet into the crack and the crack propagation effect.

[0036] Specifically, the pressure distribution image can be obtained by real-time acquisition and recording of the output data of the pressure sensor array, and the pressure distribution image is an image representing the pressure distribution of the high-voltage pulse jet. Using data analysis methods, the penetration of the high-voltage pulse jet into the crack and the crack propagation effect can be obtained by processing the pressure distribution image.

[0037] S40, acquiring and processing the pressure distribution image under the action of the high-voltage pulse jet to obtain the penetration of the high-voltage pulse jet into the crack and the crack propagation effect.

[0038] In an exemplary embodiment, step S60 can include the following steps:

[0040] S320, acquiring the pressure distribution image under the action of the high-voltage pulse jet;

[0041] S330, obtain the penetration of the high-pressure pulsed jet flow to the crack and the crack propagation effect;

[0042] S340, process the pressure distribution image based on the data analysis method.

[0043] In the exemplary embodiment, before step S40, the following steps can also be included:

[0044] S410, connect the pressure sensor array with the data acquisition system;

[0045] S420, calibrate the pressure sensor to ensure accurate measurement;

[0046] S430, perform a fracturing reconstruction experiment based on the high-pressure pulsed jet flow to obtain the pressure change under the action of the high-pressure pulsed jet flow.

[0047] S50, based on the high-speed camera, obtain and analyze the flow condition and jet angle data of the high-pressure pulsed jet flow, and optimize the hydraulic parameters and improve the design of the high-pressure pulsed jet flow.

[0048] In the exemplary embodiment, step S50 can include the following steps:

[0049] S510, based on the high-speed camera, capture the motion image of the high-pressure pulsed jet flow;

[0050] S520, obtain the flow condition and jet angle data of the high-pressure pulsed jet flow;

[0051] S530, analyze and verify the results of the flow condition and jet angle data of the high-pressure pulsed jet flow, thereby optimizing the hydraulic parameters and improving the design of the high-pressure pulsed jet flow.

[0052] In the exemplary embodiment, before step S50, the following steps can also be included:

[0053] S510, obtain the motion trajectory and morphological changes of the high-pressure pulsed jet flow in the physical model.

[0054] S60, analyze the monitoring data of the pressure sensor array, obtain the pressure distribution and propagation path of the high-pressure pulsed jet flow, and verify the influence of the optimized hydraulic parameters on the pressure distribution.

[0055] Specifically, for the monitoring data of the pressure sensor array, the data can be analyzed by mathematical model and calculation method to obtain the pressure distribution and propagation path of the high-pressure pulsed jet flow, and verify the influence of the optimized hydraulic parameters on the pressure distribution.

[0056] S70, obtain the flow condition and crack propagation effect of the high-pressure pulsed jet flow, and compare and verify with the experimental results.

[0057] In the exemplary embodiment, before step S70, the following steps can also be included:

[0058] S710, obtaining monitoring data of the high-speed camera;

[0059] S720, processing the monitoring data of the high-speed camera based on image processing and analysis methods.

[0060] Specifically, for the monitoring data of the high-speed camera, the data can be processed by image processing and analysis methods, the flow situation and crack propagation effect of the jet flow are observed, and the results are compared and verified with the experimental results.

[0061] Based on this, we have incorporated new innovative algorithms, as follows:

[0062] For the monitoring data of the pressure sensor array, data analysis and result verification can be performed in the following ways:

[0063] Data processing: The pressure data obtained by the sensor is sorted and processed, including denoising, filtering, and correction steps, to ensure the accuracy and reliability of the data.

[0064] Pressure distribution analysis: Using mathematical models and calculation methods, the processed data is analyzed for pressure distribution. By using interpolation methods, discrete pressure data can be interpolated into continuous pressure distribution graphs to better observe and analyze the pressure propagation path.

[0065] Further, pressure distribution analysis can be performed by using interpolation methods to interpolate discrete pressure data into continuous pressure distribution graphs to better observe and analyze the pressure propagation path.

[0066] The hydraulic parameter optimization method based on numerical simulation test provided by the embodiments of the present application can intuitively observe and analyze the motion of high-pressure pulse jet flow through a high-speed camera, further understand the mechanism of high-pressure pulse jet flow on cracks, and evaluate the effect of high-pressure pulse jet flow under different parameters, which is convenient for observing the flow situation and crack propagation effect of high-pressure pulse jet flow, and comparing and verifying the experimental results, thereby improving the fracturing effect of oil and gas reservoirs; through the monitoring data of the pressure sensor array, the pressure distribution and propagation path of the high-pressure pulse jet flow are obtained, and the influence of the optimized hydraulic parameters on the pressure distribution is verified, so as to ensure that the optimized hydraulic parameters can improve the fracturing effect of oil and gas reservoirs.

[0067] On the basis of the above embodiments, with reference to Figure 2 Another embodiment of the present application also provides a hydraulic parameter optimization device based on numerical simulation test. The hydraulic parameter optimization device 300 based on numerical simulation test can include the following modules:

[0068] Physical model 310 is placed above the experimental platform;

[0069] A pressure sensor array 320 is uniformly arranged on the surface of the physical model to record the pressure distribution of the physical model under the action of a high-pressure pulse jet;

[0070] The data acquisition system 330 is electrically connected to the pressure sensor array and is used to acquire and record the output data of the pressure sensor array in real time.

[0071] A high-speed camera 340 is mounted above the experimental platform to capture the trajectory and morphological changes of the high-pressure pulse jet in the physical model.

[0072] Specifically, in the digital model experimental setup, a pressure sensor array is designed and mounted on the surface of the physical model to record the pressure distribution under the action of a high-pressure pulsed jet. A highly sensitive, high-resolution, and scalable pressure sensor array is designed. The pressure sensors are evenly distributed on the surface of the physical model to cover the entire model area. Furthermore, the position and number of each sensor need to be determined in advance for subsequent data analysis and result verification.

[0073] A high-speed camera was installed on the experimental platform and placed at an appropriate position and angle to ensure that it could fully capture the motion trajectory and morphological changes of the high-pressure pulse jet in the model, and to capture the jetting process of the high-pressure pulse jet with the best field of view.

[0074] Furthermore, before the experiment begins, the high-speed camera needs to be set up and calibrated to ensure it can record the motion of the high-pressure pulsed jet at a sufficiently high frame rate and resolution. The camera's exposure time and frame rate also need to be high enough to capture the details and rapid changes in the jet. A fracturing experiment using a high-pressure pulsed jet is conducted, and the jet's motion images are recorded using a high-speed camera. Depending on the experimental requirements, multiple experiments can be performed, recording jet motion images under different parameters.

[0075] Based on the above embodiments, this application also provides a computer-readable storage medium, see reference. Figure 3The computer-readable storage medium shown is an optical disc 50, on which a computer program (i.e., a program product) is stored. When the computer program is run by a processor, it implements the steps described in the above-described method implementation, such as: acquiring pressure distribution images of the physical model under the action of a high-pressure pulsed jet based on a pressure sensor array; acquiring the pressure changes and propagation path of the high-pressure pulsed jet; analyzing the pressure distribution images to acquire the penetration of the high-pressure pulsed jet into the crack and the crack propagation effect; acquiring and processing pressure distribution images under the action of the high-pressure pulsed jet to acquire the penetration of the high-pressure pulsed jet into the crack and the crack propagation effect; acquiring and analyzing the flow and jet angle data of the high-pressure pulsed jet based on a high-speed camera, and optimizing hydraulic parameters and improving the design of the high-pressure pulsed jet; analyzing the monitoring data of the pressure sensor array to acquire the pressure distribution and propagation path of the high-pressure pulsed jet, and verifying the influence of the optimized hydraulic parameters on the pressure distribution; acquiring the flow and crack propagation effect of the high-pressure pulsed jet, and comparing and verifying it with experimental results. The specific implementation methods of each step will not be repeated here.
