大洋钻孔合成地震记录标定及其对南海科学深钻的指导意义

The technology of compound seismic record demarcation and its guidance for deep drilling in the South China Sea

本文基于合成地震记录标定技术手段,对在南海中央海盆实施的三口大洋钻探的钻孔1148、U1431和U1433的数据进行合成地震记录标定。利用过钻孔的地震剖面划分对比地震反射界面,并依此解释中央海盆的沉积层序,同时确定其地质年代属性。本研究成果对南海下一步的科学深钻的实施具有重要的指导意义。

Based on the technology,the data of 1148>U1431 and U1433 wells,which are located in the Centre Basin of the South China Sea,have been used for the compound seismic record demarcation in this paper.By dividing and comparing the seismic reflective boundaries on the seismic profiles throng wells,the depositional sequences of the Centre Basin have been interpreted and their geological ages have been confirmed.This research technology and the result will be an important guidance for the next deep drilling in the South China Sea.
