Description

Technical Field

[0001] This utility model relates to a water area fixing device for a seismic exploration node instrument, and particularly to a construction fixing device for a Kunteng node seismic instrument in a water network area, belonging to the field of specialized technical technology. Background Technology

[0002] Seismic exploration, based on the principles of geology and physics, utilizes methods from electronics and information science to artificially induce crustal vibrations that generate elastic waves. These elastic waves propagate into the subsurface medium, and instruments record the vibrations at various points on the surface after the event, indirectly inferring underground geological structures and ultimately locating potential oil and gas traps. Seismic exploration methods are widely used in the general survey and exploration of oil, natural gas, and coalfields. During operation, seismic sources are deployed at the surface to generate and collect seismic wave information, while seismic detectors are buried at the surface to receive the vibration data.

[0003] The mainstream wired seismic instrument systems in international seismic exploration are represented by the 428XL and 508XT instruments manufactured by SERCEL of France. These systems hold a major market share both domestically and internationally. Wireless instrument systems, primarily consisting of wireless instruments and nodal points, are currently manufactured by numerous companies and mainly serve as an effective supplement to wired instruments, applied in complex water networks, cliffs, and densely populated urban areas.

[0004] With the further development of exploration technology and the deepening of exploration areas, clients are increasingly demanding low-cost exploration. Project construction areas are becoming larger, and the number of acquisition channels is increasing, while the cost per unit area is gradually decreasing. Previously, cabled instruments were used for acquisition within these areas, but with the increase in the number of channels, the failure rate of the arrays is also increasing, becoming a major bottleneck for efficient acquisition. Therefore, nodal instruments are finding increasingly diverse applications and represent a future trend for low-cost, high-efficiency acquisition.

[0005] The widespread adoption of the new nodal seismic acquisition system has freed seismic teams from the constraints of long-distance and radio communications on seismic acquisition operations, effectively improving their field productivity. It represents a revolutionary breakthrough in seismic acquisition, demonstrating a transformation distinct from traditional methods. The Kunteng nodal instrument is a single unit integrating an acquisition station, battery, and geophone. It features small size, light weight, and long continuous operating time, fully meeting the needs of single-point, high-density exploration. It also significantly improves construction efficiency in complex areas and reduces HSE risks, becoming a future trend for low-cost, high-efficiency acquisition. The Kunteng nodal instrument automatically powers on when tilted less than 30° for 10 seconds and automatically powers off when tilted greater than 30° for 3 seconds. With the expanding application of nodal instruments, the nodal seismic acquisition system has the following characteristics in water-based operations: the nodal instrument must be located above the water surface and use satellite signal timing for normal operation; an external underwater geophone is required to pick up seismic signals; and the nodal instrument's field acquisition time is relatively long, generally 10–30 days. Therefore, the traditional method of fixing the Kunteng node instrument in water construction involves placing it on a bamboo, wooden, or iron pole or frame on the bottom of the water or inserting it into the silt layer. The Kunteng node instrument is then tied to the pole or frame with ropes or plastic nets. However, this method has several drawbacks: the binding is cumbersome, the binding effect is poor, and the instrument is prone to loosening and slipping; the Kunteng node instrument exhibits significant variations in posture, and excessive tilt can lead to data loss and quality accidents; untying and retrieving the instrument is laborious, rope handling is time-consuming, the lifespan is short, and losses are high, making storage difficult. Utility Model Content

[0006] The purpose of this invention is to overcome the problems existing in the current construction methods and provide a fixing device for seismic exploration node seismographs in inland water network areas. This device can change the current extensive operation method of node seismographs in field construction, improve the construction standards at the work site, control the tilt angle of the node seismograph, ensure the stable operation of the equipment, and thus effectively improve the acquisition efficiency.

[0007] Technical solution:

[0008] A water-based fixing device for a seismic exploration node instrument includes a lead screw, a steel rod, a clamp, and a frame. The lead screw and the clamp are welded to both ends of the steel rod, and the axis of the lead screw is perpendicular to the plane of the clamp. The lead screw is matched with the bottom pitch of the Kunteng node instrument. The bottom of the frame is directly inserted into the silt layer and protrudes above the water surface. The frame diameter is 25-45mm, and materials such as metal, bamboo, wooden handles, or branches can be selected according to the construction environment. The clamp is fixed to the part of the frame that protrudes above the water surface.
