利用反射地震水体处理技术探测东海冲绳海槽天然气水合物

Detecting Gas Hydrate by Using Reflection Seismic Water Processing Technology in Okinawa Trough,East China Sea

该文针对东海冲绳海槽盆地的二维地震资料,采用地震海洋学的方法,对水体反射数据进行处理,发现了典型的羽状反射流特征,结合BSR等异常,综合分析认为是渗漏型天然气水合物存在的证据,证明水体处理技术在东海冲绳海槽盆地天然气水合物的研究中是可行的、有效的。

Based on the 2D seismic data of the Okinawa Trough in the East China Sea,the method of Seismic Oceanography is introduced to process the water column reflection data.The typical pinnate reflection flow characteristics are found in the processed sections and considered as the evidence of leakage gas hydrate according to the BSR and other abnormalities.This paper shows the method of water column processing technology is feasible and effective in the study of gas hydrate in Okinawa Trough Basin of the East China Sea.
