Description

Technical field:

[0001] The invention belongs to the field of oil and gas exploration equipment, and in particular relates to a geophone straightening and deployment integrated device suitable for soft formations such as deserts. Background technology:

[0002] In the field of oil exploration, seismic exploration is an extremely important technical means, which infers the underground geological structure and the distribution of oil and gas reservoirs by artificially exciting seismic waves and using detectors to receive reflected wave signals. Whether the detector can ensure the "flat, stable, straight, straight, and tight" placement standards and good coupling with the earth largely determines the quality of the seismic waves received by the detector.

[0003] There are many challenges in conducting seismic exploration in soft strata such as deserts. Desert strata are mainly composed of loose sand particles, which have extremely low shear strength and bearing capacity. Traditional geophone layout methods make it difficult to ensure the vertical placement and stable fixation of geophones in such soft strata, resulting in deviations in the received seismic wave signals, affecting the accuracy and resolution of seismic data.

[0004] In addition, the desert area has strong winds and sand, and the surface is prone to flow. Conventional detector fixing devices are difficult to resist the displacement changes of the surface, which can easily cause the detector to be displaced or buried, which not only increases the maintenance cost and workload of field operations, but also interrupts data collection or makes the collected data discontinuous and unreliable due to the change of the detector position. Moreover, due to the inconvenient transportation and harsh working environment in desert areas, high requirements are also placed on the portability, ease of installation and operability of the detector straightening and deployment devices. Some existing detector fixing devices suitable for ordinary hard formations cannot effectively function in soft formations in deserts. Therefore, there is an urgent need for a detector straightening and deployment integrated device specifically suitable for soft formations such as deserts to improve the efficiency and data quality of seismic exploration operations in desert areas and reduce exploration costs and risks. Summary of the invention:

[0005] The present invention ensures that the geophone for oil and gas exploration always maintains a vertical and stable state after the tail vertebrae are fully inserted in the desert, and prevents the position of the geophone from changing. At the same time, the automatic laying and recovery of the geophone can be realized through the mechanical arm in conjunction with the hydraulic device, thereby improving the laying and recovery efficiency of the geophone, meeting the placement standards of the geophone "flat, stable, straight, straight, and tight", and providing an integrated device for geophone straightening and laying suitable for soft formations such as deserts.

[0056] Working principle of the present invention:

[0057] The present invention proposes an integrated device for geophone straightening and deployment suitable for soft strata such as deserts. The principle of the invention is divided into the following steps:

[0058] The first step is the initial state and the moving stage. In the initial static state, the telescopic plate in the detector straightening device extends out of the positioning groove, so that the detector straightening device is suspended on the positioning hole. When the work starts, the drive motor installed on the edge of the base starts to drive the crawler device to operate, and the entire device can move on soft formations such as deserts until it reaches the designated work site and stops moving, preparing for subsequent operations.

[0059] The second step is the grabbing and preparation stage of the detector straightening device. At this time, the multi-stage telescopic rod in the moving manipulator device begins to extend downward in the vertical direction. When it is extended to a certain distance above the detector straightening device, the manipulator device rotates itself to align the first transmission shaft with the second transmission shaft. At the same time, the clamping plate on the manipulator device is facing the clamping groove. As the multi-stage telescopic rod continues to extend downward, the first transmission shaft can be smoothly and correctly connected with the second transmission shaft, and the clamping plate can be accurately embedded in the clamping groove, thereby tightly clamping the detector straightening device. After that, the multi-stage telescopic rod stops working, and the preparation work for grabbing the detector straightening device is completed.

[0060] The third step is the lowering and fixing stage of the detector straightening device. When the manipulator device successfully completes the connection with the detector straightening device, the rotation of the first transmission shaft drives the rotation of the second transmission shaft, and the second transmission shaft drives the turntable to rotate through the key. The rotation of the turntable causes the cylindrical block to move in the arc groove, and the movement of the cylindrical block causes the telescopic disk to move in the sliding groove in a straight line, thereby causing the telescopic disk to retract back into the inside of the detector straightening device, and releasing the suspension lock of the telescopic disk on the detector straightening device. Then, the hydraulic device is started, and the hydraulic rod moves downward, driving the detector straightening device clamped by the manipulator device to be pressed down into the soil. When the buried depth reaches the specified depth, the hydraulic device stops working. Subsequently, the rotation of the first transmission shaft drives the rotation of the second transmission shaft, so that the telescopic disk of the closing disk extends out of the positioning groove again, thereby preventing the detector position from changing due to the flow of sand, thereby achieving the function of fixing the detector. After the fixation is completed, the clamping plate of the manipulator device is released, the multi-stage telescopic rod retracts upward, the hydraulic rod moves upward, and all components return to their initial positions. When multiple geophones need to be arranged, the hydraulic device can be rotated to the top of other geophone straightening devices suspended on the hole under the rotation of the hydraulic base, and the above process is repeated to complete the arrangement of the geophones.

[0061] The fourth step is the detector recovery stage. When recovering the detector, the hydraulic device presses down, and when the multi-stage telescopic rod reaches a certain distance above the detector straightening device, the manipulator device rotates itself to align the first transmission shaft with the second transmission shaft. At this time, the clamping plate on the manipulator device is facing the clamping groove. Next, the multi-stage telescopic rod extends out, so that the first transmission shaft and the second transmission shaft are correctly connected and the clamping plate is correctly embedded in the clamping groove and clamped. Then the multi-stage telescopic rod stops working. When the manipulator device successfully completes the connection with the detector straightening device, the first transmission shaft rotates to drive the second transmission shaft, and the second transmission shaft drives the turntable to rotate through the key. The rotation of the turntable causes the cylindrical block to move in the arc groove, and the movement of the cylindrical block causes the telescopic disk to move in a straight line in the sliding groove, thereby retracting the telescopic disk back into the detector straightening device. The hydraulic device moves up, and the manipulator device lifts the detector straightening device. When the detector righting device reaches above the hole, the first transmission shaft rotates again to extend the telescopic disk, the manipulator releases the detector righting device, and the detector righting device is re-suspended above the positioning hole to complete the recovery work.
