基于OBS的天然气水合物地震响应研究进展
|
摘要
OBS(海底地震探测仪)探测技术是继BSR(似海底反射)的AVO(叠前反演)模拟技术之后兴起的新型地震探测技术。因OBS可以获得更高的分辨率,且随着广角OBS地震探测技术的发展,OBS在新型能源-天然气水化合物的勘探上取得了较大进展。本文分析了近几年来国内OBS的发展近况,列举了国际上成功利用OBS取得进展的案例,并对国内研究进展进行了总结。
The OBS(Ocean Bottom Seismograph) detection technology is a newly rising seismic detection technology after BSR's(Bottom simulating reflector)AVO(prestack inversion) simulation technology.Due to the OBS can get higher resolution and the later development of wide-angle OBS seismic detection technology,the OBS has made great progress in the exploration of the natural gas hydrate.The article analysises the development of domestic OBS recent situation,lists the successful international cases of the use of OBS,and summarizes the research progress of domestic in recent few years.
