摘　　要：在深水油气田勘探开发过程中,井场地质灾害的调查评价是一项不可缺少的重要环节。深水井场调查较浅水相比,投入成本巨大。利用三维高分辨率地震资料进行深水油气田井场地质灾害研究过程中,积累了一定经验,认为油气勘探过程中的三维地震浅层数据经高分辨率处理后,在一定条件下可满足深水油气田区井场地质灾害的研究和评价。以琼东南勘查区为例,介绍了利用三维地震数据经"三高"特殊处理,进行深水油气田井场地质灾害解释的初步成果。Due to the complexity of geological conditions,there are a lot of geohazards in deepwater areas,which may turn to catastrophes without extensive and prudent consideration.Therefore,in the process of deepwater petroleum exploration and development,site investigation and geohazards assessment are indispensible.Comparing to shallow water area,the cost for conducting site investigation in deepwater is tremendous.In recent years,we have been using 3D exploration seismic data to indentify geohazards at well sites.After high-resolution reprocess,in some cases it is possible to use exploration seismic data to detect and assess geohazards.This paper introduces a case from the Qingdongnan block.
