Kawasoko ground structure analysis method using the streamer and electrical resistivity survey system

摘要

In Disclosed, Kawasoko ground structure analysis method using the same and streamer electric resistivity survey equipment can check the bedrock boundary between the thickness of the deposited layer of river bottom of the lake or river in the fast time is provided . The Streamer electrical resistivity survey system of the present invention comprises, and an electrical resistivity survey system to probe the structure of the underwater ground by using a survey vessel, is coupled to the survey vessel, a plurality of electrodes attached a multi-channel electrical resistivity spacecraft measuring the electrical resistivity of a plurality of electrodes and the streamer cable, is mounted on the survey vessel and attached to the streamer cable, is mounted on the drilling vessel, the position of the drilling vessel RTK of the first to be measured in real time And GPS (Real Time Kinematic GPS), provided at the terminus of the streamer cable, I comprising, RTK GPS and the second to measure in real time the location of the terminus of the streamer cable.
