Acquisition cable

Abstract

The invention relates to an acquisition cable. The acquisition cable comprises a first cable connector, a first compartment segment connected with the first cable connector, a second cable connector, a second compartment segment connected with the second cable connector, an acquisition segment, a first double-charging rubber hole compartment arranged between the acquisition segment and the first compartment segment, a second double-charging rubber hole compartment arranged between the acquisition segment and the second compartment segment, and a voltage detector and an acquisition circuit module which are arranged in the acquisition segment, a power supply wire harness, a high speed transmission wire, a communication wire harness, and a cable pull rope arranged between the first compartment segment and the second compartment segment, wherein the voltage detector is used for acquiring earthquake data, the acquisition circuit module is used for processing the earthquake data acquired by the voltage detector, earthquake data acquisition is carried out according to a command of the communication wire harness, the power supply wire harness is used for supplying power for the acquisition circuit module, the high speed transmission wire is used for transmitting the earthquake data after being processed by the acquisition circuit module to an on-board system, and the communication wire harness is used for transmitting a command issued by the on-board system to the acquisition circuit module.

Description

Technical field [0001] This article involves but is not limited to geophysical prospecting technology, especially a collection cable. Background technique [0002] Seismic streamer acquisition is one of the most important methods of marine geophysical exploration; underwater acquisition cable is the core equipment of the seismic streamer acquisition system. [0003] The seismic streamer is composed of several sections, which are the leading section, the front elastic section, several collection cables, and the tail elastic section in order from near to far from the ship. The leading section is used to tow the entire seismic streamer, and the seismic wave signals collected by the collection cable are gradually transmitted to the shipborne seismograph through the front elastic section, the leading section and the ship-borne deck cable; the front elastic section is located in the leading section and the acquisition Between the cables, it is used to reduce the vibration and noise of t...

AI Technical Summary

Problems solved by technology

Imported acquisition cables are not only expensive, but also have many restrictions to prevent them from being used for military purposes: ①Working depth: no greater than 50 meters; ②Track spacing: no less than 12.5 meters; ③Sampling rate: In the case of long cables, Low sampling rate configuration

However, when conducting exploration operations, the depth of the acquisition cable is often greater than 50 meters, and the track spacing is often not limited to 12.5 meters, which leads to restrictions on exploration operations

However, the relevant technology does not disclose the specific implementation scheme of the acquisition cable.
