摘要埕岛油田东部斜坡带下第三系油藏以三角洲、浊积扇隐蔽岩性油气藏为主,是近年在该区发现的又一含油层系。该带储层埋藏深、厚度变化大,油气聚集成藏复杂。本文对利用测井约束反演技术进行储层预测方法进行了探讨,通过合成地震记录标定、子波提取和薄层识别等技术,结合本区特点,对储层进行追踪、预测,查清了该地区储层的分布规律,落实了有利的岩性圈闭,获得了较好的效果。

Abstract：The Neogene reservoir in east-slope-belt of Chengdao Oilfield primarily is subtle lithologic reservoir formed by delta and turbidite fan and also is a new oil-bearing formation discovered in recent years in the region.Reservoir of the belt is deep buried and large thickness variation that made oil-gas accumulation more complicated.The paper approached method for reservoir prediction by using logging-restrained inversion technique,traced and predicted reservoir through techniques of calibrating of synthetic seismic section,wavelet-picking and thin-layer identification etc combining characters of the region,found out the rule of reservoir distribution in the region,fixed prospective lithologic traps and achieved better results.

Key words： logging-restrained inversion synthetic seismic section reservoir
