摘要：
The proprietary deep-towed, multi-channel high-resolution seismic system (Kuiyang-ST2000)consisting of a plasma electric spark source with the advantages of high sound source level, wide frequency band, and multichannel receiver array(48 channel, interval 3.125m) is capable of operating at 2000m in ocean.During operating, the source and the receiving cable are towed to the offshore floor (less than 100m).This shortens the distance between the system and the detected target, reduces the absorption and attenuation of seawater during the propagation of seismic signals, and can overcome multiples, bubbles and ocean noises caused by towing streamers on sea surface.The first test on the ST2000 system was completed in the E sea area of the South China Sea (the regional sea floor is about 1500m deep, and the system working depth is about 1400m).The final imaging profile after fine processing of test data has verified the superiority of the Kuiyang-ST2000 system, which overcomes the shortcomings of insufficient resolution of conventional marine multi-channel seismic systems. © 2020, Editorial Department OIL GEOPHYSICAL PROSPECTING.
