Description

Technical Field

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

[0002] In the current geophysical exploration industry, seismic detectors have always been the main device for picking up seismic waves due to their simple structure, low cost and high adaptability. They are also one of the most important links in determining the quality of seismic data. At present, in geophysical exploration projects, a variety of detector cores are often configured for seismic data collection. Due to the different manufacturers, models, sizes, and series-parallel combinations of the detector cores, the quality of seismic data will be affected to varying degrees. Therefore, in the early stage of the exploration project construction, it is necessary to test and evaluate the parameters such as the detector model, number of cores, and series-parallel combination to achieve the best reception effect, thereby ensuring the final quality of seismic data.

[0003] Traditional testing and evaluation methods are to evaluate the detector core using a detector tester, a vibration table, or by collecting seismic data in the field. The detector tester can only evaluate some basic performance of the detector core, and cannot directly compare the response of different detector cores to the same seismic excitation signal; due to its own load-bearing problems and technical limitations, the vibration table can only test a single detector core, and cannot test multiple cores at the same time, and cannot change the series-parallel combination of the detector core; conventional field data collection methods such as pit and pile number receiving effect comparison methods, due to differences in the location of the detector burial, the degree of burial tightness, the shape of the tail vertebrae, the length of the tail vertebrae and other factors, will cause the coupling of different detector cores to be inconsistent, and it is impossible to truly achieve the same coupling environment for different detector cores, which leads to 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 to 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 tightness of soil, different shapes and lengths of geophone tail vertebrae due to different manufacturers or models during seismic data acquisition, the received excitation signals cannot be homogenized, One object of the present invention is to provide a detector performance evaluation device to achieve the effect of having the same coupling environment for multi-core detectors of multiple manufacturers, multiple models, multiple specifications, and multiple series-parallel combinations; Another object of the present invention is to provide a performance evaluation method for multi-core geophones of multiple manufacturers, multiple models, multiple specifications, and multiple series-parallel combinations. By controlling the series-parallel combination state of the geophone cores installed inside, it is possible to connect any geophone tester to evaluate the basic performance of the geophone cores, and it is also possible to connect all current wired instruments and node instruments with external geophone interfaces and supporting real-time data transmission to collect seismic data, so as to provide a reliable geophone configuration solution. The third object of the present invention is to provide a computer device and a computer-readable storage medium for executing the above method.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A detector performance evaluation device comprises: an upper shell and a lower shell fixedly connected to the upper shell, wherein: The upper shell includes external connection components and internal conversion communication components, which are exposed to the ground when buried: The external connection components include a detector plug and a locking component, The detector plug is plugged into the outside of the upper shell and is used to connect with a detector tester to perform a detector core performance test, or to connect with a seismic instrument to perform a polarity knock test or seismic data acquisition; The locking component is used to lock the connection between the geophone plug and the geophone tester or seismic instrument; The internal conversion communication component is fixedly connected to the top wall inside the upper shell, and includes a detector core series-parallel state conversion component, a communication component and a power supply. The detector core body series-parallel state conversion component is connected to the communication component and is used to configure the series-parallel combination state of each detector core body; The communication component is used to send the serial-parallel combination state of the detector core or receive the command of the serial-parallel combination state of the detector core; The power supply is connected to the detector core body series-parallel state conversion component and the communication component, and is used to supply power to the series-parallel state conversion component and the communication component; The lower shell includes the detector core slot and the detector tail cone, which are buried underground when buried: The detector core slot is fixedly connected to the inside of the lower shell and is a rigid fixed structure for storing detector cores of different manufacturers, different models, different sizes and different series-parallel combinations; The tail cone of the detector is located on the outer bottom surface of the lower shell and is fixedly connected to the outside of the lower shell to achieve direct coupling with the soil.

[0007] Furthermore, the detector has three tail vertebrae, and the number of slots in the detector core slot is at least 8, and the size can be adjusted to match the selected detector core. The detector cores of different sizes are inserted into the detector slots 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. The 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 connecting components is consistent with the number of slots in the detector core slot and is in a one-to-one correspondence.

[0008] Further, the detector core series-parallel state conversion component is a detector series-parallel switch circuit; The communication component is a communication chip; The power source is a built-in lithium battery; The fixed connection between the upper shell and the lower shell is a threaded connection; The fixed connection between the internal conversion communication component and the upper housing is a threaded connection; The fixed connection between the detector core slot and the lower shell is a threaded connection; The fixed connection between the tail cone of the detector and the lower shell is a threaded connection.

[0009] Furthermore, the seismic instrument is a wired instrument or a node instrument having an external detector interface and supporting real-time data transmission.

[0010] The present invention also provides a detector performance evaluation method, comprising the following steps performed in sequence: S1. In the early stage of geophysical exploration projects, the geophone performance evaluation device is used to encapsulate the geophone cores of different manufacturers, models and sizes, and buried in the area where the geophysical exploration project is to be carried out, ensuring that the device is tightly combined with the soil and perpendicular to the horizontal plane; Connecting the external connection components of the detector performance evaluation device to a detector tester, performing a performance test on each detector core and removing the detector cores that fail the test; S2. The external connection components of the detector performance evaluation device are disconnected from the detector tester and connected to the seismic instrument for a polarity knock test. After the polarity knock test is completed, the connection with the seismic instrument is disconnected, the knock record is checked, and the detector core that fails the test is eliminated; S3. According to the test requirements, the detector core series-parallel state conversion component of the detector performance evaluation device is used to configure the series-parallel combination of each qualified detector core, and the seismic instrument is connected according to the configuration; S4. Use the excitation signal to test the response of the detector cores of different manufacturers, different models, and different series-parallel combinations in the detector performance evaluation device to the highly consistent excitation signal, and receive the test data through the communication component of the detector performance evaluation device, and perform performance evaluation through the data analysis server.

[0011] Furthermore, the seismic instrument is a wired instrument or a node instrument having an external detector interface and supporting real-time data transmission; The excitation signal is generated by a well gun, a seismic source or other excitation modes. The data analysis server can perform comprehensive analysis and comparison on the test data in the frequency domain and the time domain.

[0012] Furthermore, the test data is transmitted to the data analysis server in step S4 as follows: 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 WIFI or 4 / 5G network for automatic data collection and aggregation, and after the aggregation is completed, the data is packaged and sent to the data analysis server.

[0013] Furthermore, the method further includes step S5, which is to execute steps S1 to S4 in a loop.

[0015] The present invention also provides a computer-readable storage medium, wherein the computer-readable storage medium stores instructions for executing any of the detector performance evaluation methods described above.

[0016] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art: (1) The detector performance evaluation device proposed in the present invention ensures that the detector cores encapsulated in the device have completely consistent detector coupling conditions and receive completely consistent excitation signals, and can provide stable and reliable detector core test data for geophysical exploration projects.

The detector cores of different sizes are inserted into the detector slots in sequence, and three small trapezoidal wedges are inserted at equal intervals into the gap between the detector core and the inner wall of the slot. The 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 upper cover of the detector performance evaluation device is tightly closed to ensure that the package is intact, and the device is buried in the soil of the test area so that the device is tightly combined with the soil and perpendicular to the horizontal plane to ensure that the device does not move slightly in any direction due to vibration; Connect the detector plugs to the detector tester to test the detector core group.
