Description

Technical Field

[0001] The present invention belongs to the field of seismic exploration equipment and relates to seismic geophone technology, in particular to a geophone performance evaluation method, device, equipment and medium. Background Art

[0002] In the current geophysical exploration industry, geophones, due to their simple structure, low cost, and high adaptability, have long been the primary device for picking up seismic waves. They are also one of the most important factors in determining the quality of seismic data. Current geophysical exploration projects often deploy a variety of geophone cores for seismic data acquisition. Factors such as the different manufacturers, models, sizes, and series-parallel combinations of these geophone cores can all have varying degrees of impact on seismic data quality. Therefore, early in the exploration project, it is necessary to test and evaluate parameters such as the geophone model, number of cores, and series-parallel combinations to achieve optimal reception and ultimately ensure the quality of the final seismic data.

[0003] Traditional testing and evaluation methods involve evaluating geophone cores using geophone testers, vibration tables, or by collecting seismic data in the field. Geophone testers can only evaluate some of the basic performance of geophone cores and cannot directly compare the responses of different geophone cores to the same seismic excitation signal. Due to its inherent load-bearing capacity and technical limitations, vibration tables can only test a single geophone core and cannot test multiple cores simultaneously, nor can they change the series and parallel connection of geophone cores. Conventional field data collection methods, such as pit and pile receiving effect comparison methods, can cause inconsistencies in the coupling of different geophone cores due to differences in geophone burial position, burial tightness, tail vertebra shape, and tail vertebra length. This makes it impossible to truly achieve identical coupling environments for different geophone cores, resulting in the inability to achieve completely consistent test and evaluation conditions, making the test and evaluation results unreliable.

[0004] Therefore, it is urgent to invent a new method and device to realize reliable performance evaluation of multi-core detectors of multiple manufacturers, multiple models, and multiple series-parallel combinations under exactly the same coupling environment, and provide a reliable detector configuration solution. Summary of the Invention

[0005] In order to solve the problem of geophone performance evaluation caused by the different locations of buried geophones, different soil tightness, different geophone tail cone shapes and lengths due to different manufacturers or different models during seismic data acquisition, the received excitation signals cannot be homogenized.

[0006] One object of the present invention is to provide a detector performance evaluation device to achieve the same effect of coupling environment for multi-core detectors of multiple manufacturers, multiple models, multiple specifications, and multiple series and parallel combinations;

[0007] Another object of the present invention is to provide a performance evaluation method for multi-core geophones from multiple manufacturers, models, specifications, and in various series-parallel combinations. By controlling the series-parallel combination of internally installed geophone cores, the method can be connected to any geophone tester to evaluate the basic performance of the geophone cores. It can also be connected to all currently available wired instruments and node instruments with external geophone interfaces and support for real-time data transmission to collect seismic data, thereby providing a reliable geophone configuration solution.

[0008] The third object of the present invention is to provide a computer device and a computer-readable storage medium for executing the above method.

[0009] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0018] The power supply is connected to the series-parallel state conversion component and the communication component of the detector core body, and is used to supply power to the series-parallel state conversion component and the communication component;

[0019] The lower shell includes the detector core slot and the detector tail cone, which is buried underground when buried:

[0020] The detector core slot is fixedly connected to the interior of the lower housing and is a rigid fixed structure for storing detector cores of different manufacturers, different models, different sizes and different series-parallel combinations;

[0021] The tail cone of the detector is located on the outer bottom surface of the lower shell and is fixedly connected to the outer portion of the lower shell to achieve direct coupling with the soil.

[0022] Furthermore, the detector has three tail vertebrae, and the number of slots in the detector core slot is at least 8, and its size can be adjusted to match the selected detector core. Detector cores of different sizes are inserted into the detector slot in turn, and three small trapezoidal wedges are inserted at equal intervals in the gap between the detector core and the inner wall of the slot. A fixing lock is screwed into the upper part of the detector core to ensure that the detector core does not move in any direction up, down, left, or right inside the slot; the number of external connection components is consistent with the number of slots in the detector core slot and is in a one-to-one correspondence.

[0023] Furthermore, the detector core series-parallel state conversion component is a detector series-parallel switch circuit;

[0024] The communication component is a communication chip;

[0025] The power supply is a built-in lithium battery;

[0026] The fixed connection between the upper shell and the lower shell is a threaded connection;

[0027] The fixed connection between the internal conversion communication component and the upper shell adopts a threaded connection;

[0028] The fixed connection between the detector core slot and the lower shell is a threaded connection;

[0029] The fixed connection between the tail cone of the detector and the lower shell adopts a threaded connection.

[0030] Furthermore, the seismic instrument is a wired instrument or a node instrument having an external detector interface and supporting real-time data transmission.

[0032] S1. At the beginning of a geophysical exploration project, use a geophone performance evaluation device to package geophone cores of different manufacturers, models, and sizes. These are then buried in the area where the geophysical exploration project will be conducted, ensuring that the device is firmly bonded to the soil and perpendicular to the horizontal plane.

The external connection components of the geophone performance evaluation device are disconnected from the geophone tester and connected to the seismic instrument for a polarity knock test. After completing the polarity knock test, disconnect the seismic instrument and check the knock records to remove the geophone core that failed the test.

[0035] S3 in accordance with the test requirements, using the detector performance evaluation device of the detector core series-parallel state conversion component configuration of each test-qualified detector core series-parallel combination, and connect the seismic instrument according to the configuration;

[0036] S4. Use the excitation signal to test the response of the detector cores of different manufacturers, models, and series-parallel combinations within the detector performance evaluation device to the highly consistent excitation signal. The test data is received through the communication component of the detector performance evaluation device, and performance evaluation is performed on the data analysis server.

[0037] Furthermore, the seismic instrument is a wired instrument or a node instrument having an external geophone interface and supporting real-time data transmission;

[0071] Example 2 A method for evaluating detector performance

[0072] This embodiment takes the designed 8-core detector as an example to perform performance evaluation. The flow chart of the performance evaluation method is as follows: Figure 4 As shown, it includes the following steps performed in sequence:

[0073] S1. Randomly select 8 detector cores of different manufacturers, models and sizes and install them into the following Figure 2 In the detector core slot shown, Figure 2 Where a01, a02, a03...a08 are slots for detector cores of any model, which can accommodate all currently known detector cores of different manufacturers, models, and sizes. Insert the detector cores of different sizes into the detector slots in sequence. Insert three small trapezoidal wedges at equal intervals into the gap between the detector core and the inner wall of the slot. Screw in the fixing lock on the upper part of the detector core to ensure that the detector core does not move in any direction inside the slot. Close the upper cover of the detector performance evaluation device to ensure that the package is intact. Bury the device in the soil of the test area so that the device is tightly bonded to the soil and perpendicular to the horizontal plane to ensure that the device does not move slightly in any direction due to vibration.

[0074] Connect the detector plugs to the detector tester to test the detector core group, such as Figure 3 As shown, Figure 3 b01, b02, b03...b08 are detector plugs. The detector tester connected to b01 tests the performance indicators of the detector core placed in position a01, and so on. If the series and parallel connection mode of the cores inside the detector performance evaluation device is changed, it is necessary to connect the corresponding detector plugs and perform the test according to the display of the detector performance evaluation device's accompanying handheld software. After the test is completed, the detector core that failed the test should be replaced or the accompanying handheld software should be used to block the detector core;

[0075] S2. Disconnect all detector plugs in the detector performance evaluation device from the detector tester and connect them to a similar wired instrument or a node instrument with an external detector and supporting real-time data transmission. Perform a polarity tapping test. The detector plugs corresponding to the detector cores that failed the test in step S1 should not be connected. After the test is complete, disconnect the plugs, check the tapping records, and replace the failed detector cores or block them using the accompanying handheld software.

[0076] S3. Use the supporting handbook software to configure the detector performance evaluation device's detector core series-parallel combination, and according to the display of the supporting handbook software, connect the corresponding detector plug to the wired instrument or a node instrument with an external detector interface and supports real-time data transmission;

[0077] S4. Use environmental noise monitoring to evaluate the test environment in real time. Noise monitoring data from wired instruments is automatically aggregated into the instrument's associated storage device. Noise monitoring data from node instruments is transmitted via a 4 / 5G network to a supporting cloud server with data encryption. Real-time analysis of noise monitoring data determines whether the noise level meets seismic data acquisition requirements.

[0078] Under the premise of ensuring that the noise level meets the requirements of seismic data acquisition, an excitation signal is generated by a well gun, and the communication chip of the detector performance evaluation device is responsible for receiving the excitation signal and performing seismic data acquisition;

[0079] For the collected test data, the wired instrument copies the data to the data analysis server through an external storage device; the node instrument with an external detector interface and supporting real-time data transmission transmits the data to the cloud server through the 4 / 5G network for automatic data collection and aggregation. After the aggregation is completed, the data is packaged and sent to the data analysis server;

[0080] The data analysis server automatically compares and evaluates the test data of detector cores from different manufacturers, models, and series-parallel combinations. By comparing waveforms, it analyzes and compares the phase, amplitude, and spectrum of the test data, confirms the optimal test data, and records the parameters of the current optimal test data, such as the detector core model, number of detector cores configured, and series-parallel combination mode.

[0081] S5. Loop through steps S1 to S4 until the optimal data for all test scenarios is obtained. Record the optimal data, including the geophone core model, number of geophone cores, and series-parallel combination method, as the final geophone core configuration for the formal acquisition of the current geophysical exploration project.
