Three-component magnetic field and three-component electric field ocean electromagnetic data collection station

Abstract

Provided is a three-component magnetic field and three-component electric field ocean electromagnetic data collection station. The three-component magnetic field and three-component electric field ocean electromagnetic data collection station is applied in ocean petroleum geological prospecting. An electric field data collection station and an electric field data collection station power source are fixed inside an ocean electromagnetic data collection station box body. The electric field data collection station is connected with three pairs of three-component electric field sensors which are arranged outside the ocean electric electromagnetic collection station box body. A pressure-resisting sealed glass ball is arranged inside the ocean electromagnetic data collection station box body, and a magnetic field data collection station, a magnetic field data collection station power source, an X-direction small-scale horizontal magnetic field sensor, a Y-direction small-scale horizontal magnetic field sensor and a Z-direction small-scale vertical magnetic field sensor are arranged inside the pressure-resisting sealed glass ball 2. According to the three-component magnetic field and three-component electric field ocean electromagnetic data collection station, a design and manufacture process for carrying out pressure-resisting sealing processing independently to a single induction coil type magnetic field sensor which is larger than 1m in length in an ocean electromagnetic data collection station box for production is simplified, and two pairs or three pairs of pole type horizontal electrodes with 10-meter pole pitch are eliminated.

Description

technical field [0001] The present invention relates to the technical field of marine petroleum geological exploration and marine geological structure and geological resource investigation equipment, in particular to marine geophysical exploration to collect three-component electromagnetic field data of natural field sources and / or artificial field sources on the seabed, which is a three-component magnetic field and three-component Electric field marine electromagnetic data collection station. Background technique [0002] At present, the marine electromagnetic data acquisition station used for production uses two or three separate induction coil magnetic field sensors with a length of more than 1 meter. Each magnetic field sensor needs to be individually pressure-resistant and sealed in packaging, which is not convenient for production and use. The marine electromagnetic data acquisition station used for production uses two pairs (E X ,E Y ) or three pairs (E X ,E Y ,E...

Problems solved by technology

[0002] At present, the marine electromagnetic data acquisition station used for production uses two or three separate induction coil magnetic field sensors with a length of more than 1 meter. Each magnetic field sensor needs to be individually pressure-resistant and sealed in packaging, which is not convenient for production and use

The marine electromagnetic data acquisition station used for production uses two pairs (E X ,E Y ) or three pairs (E X ,E Y ,E Z ) The long pole electrode with a pole distance of 10 meters is very inconvenient to operate and transport
