Problems solved by technology
When the existing marine auxiliary equipment is used, it usually has the following disadvantages: 1) The tension state and water stack information are provided by two kinds of equipment, the equipment has a single function, and the structure of the underwater equipment is complicated. Standby; 2) The digital package that provides tension status and the streamer that provides water stack information cannot be directly connected to the seismic data acquisition streamer or digital package due to the similarities and differences in the joint structure; 3) The two types of data packages that provide tension status and water stack information Equipment is an essential product for marine seismic streamer acquisition operations

The invention relates to a marine earthquake towing cable device and method capable of providing tension and water stack information. The marine earthquake towing cable device comprises a cable body, and the two ends of the cable body are provided with a head end connector and a tail end connector respectively; the data acquisition and processing device is arranged in the middle of the cable body and is used for receiving acquired data; the water stack information acquisition device is arranged at a preset position between the head end connector and the data acquisition and processing device and is used for receiving stratum reflection wave data; the tension sensing device is arranged between the data acquisition and processing device and the tail end connector, is close to the tail part and is used for acquiring an underwater tension signal; wherein the water stack information acquisition device and the tension sensing device are both electrically connected with the data acquisition and processing device, and the data acquisition and processing device is electrically connected with the shipborne recording system. According to the marine seismic towing cable equipment capable of providing the tension and water stack information, the convenience of marine seismic exploration can be improved.
Description
technical field [0001] The invention belongs to the field of marine seismic exploration, in particular to a marine seismic streamer device and method that can provide pulling force and water stack information. Background technique [0002] Seismic exploration is the most important method to find oil and gas resources, and marine seismic acquisition operation is the first step in the exploration of marine oil and gas resources. With the gradual increase in marine exploration and development and the increasing variety of marine seismic acquisition modes in recent years, easy operation, flexibility and reliability have become the goal of marine seismic exploration and acquisition equipment manufacturing companies. [0003] Marine seismic exploration usually excites seismic waves artificially, and receives formation reflection waves by several acquisition streamers towed behind the geophysical exploration ship. In order to ensure the normal operation of marine seismic streamers,...
