摘　　要：岩性勘探已逐渐成为油气勘探的主要目标。恩平凹陷岩性体是珠一凹陷的重要岩性体,是珠江口盆地岩性勘探的重要目标。而岩性勘探相比构造勘探在岩性体的岩性、物性等方面都更为复杂,需要地球物理提供更多的有效的信息。叠前弹性反演技术以叠前道集为输入,联合测井资料,可以反演得到多种弹性参数,是岩性勘探的重要方法。本文使用叠前弹性反演技术预测恩平凹陷岩性体岩性,为珠江口盆地的岩性勘探积累了经验。Lithological exploration has gradually become the main target of oil and gas exploration.Enping lithology body is an important goal of Pearl River Mouth Basin Lithological exploration.In rock lithology,physical and others,the lithological exploration are more complex than structure exploration,geophysical have to give more effective information.The pre-stack elastic inversion use pre-stack gathers as input,with log data,obtains many elastic parameter.It is an important method of lithological exploration.This article using pre-stack elastic inversion to predicts lithology of Enping lithology body,accumulate experience for the exploration of the Pearl River Mouth Basin.
