叠后地质统计学反演在大庆长垣油田的应用

经过多年的探索和研究,地震资料的反演方法已经逐渐成熟,反演成功的实例报道也不少见〔1〕。为取得较好的反演效果,本文从实际资料出发、从应用的角度对地质统计学反演的基本原理,及适用的范围进行了探讨,并应用该方法对大庆长垣油田某区地震资料进行了地质统计学反演。在反演结果剖面上清晰的识别出薄层砂体,为寻进一步挖潜剩余油指明了方向。

With many years＇ research and hard works by geo-scientists,seismic data inversion methods have been greatly improved.Many successful inversion instances have been reported.But in order to get a good inversion result,There are lots of things to be done and to be known for an inversion applier.In this research,the exploration data was studied carefully,and the geostatistics Inversion was applied to the seismic data of the studied area.On the inversed seismic profiles,one obscure lice formation within the objective interval was picked up.Prac-tice shows it is very important to choose the suitable inversion method and use all the prior geo-information for one to further looking for remaining oil.
