复杂断块油藏的地震识别与描述

The Seismic Recognition and Description of the Complex Fault Block Oil Reservoir

目前各油田都已进入高程度勘探开发阶段 ,寻找新的储量接替阵地和提高采收率成为油田发展的主要难题。经过多年的勘探 ,那些形态清楚、规模较大的构造油气藏越来越少 ,复杂断块油藏作为一种特殊的隐蔽型油气藏 ,在油气勘探中所占比重越来越大。以东营凹陷为例 ,对此类油藏的地震识别、成藏特征及描述方法等进行了较系统地分类总结 ,并列举了一些成功的实例 ,以期对其它地区的勘探有一定的借鉴作用。

At present,every oil field all get into phase of exploration and exploitation with high degree,to look for new reserves position and to raise recovery efficiency are main baffling problems of oilfield developing.To be prospected for many years,the clear and bigger structure reservoir are less and less.The complex fault block reservoir as a special concealing oil and gas reservoir,its proportions are bigger and bigger in oil and gas exploration.In the paper,taking the Dongying sag for example,we have systematically summed up the seismic recognition reservoir characteristic and description methods et al.of the kind of oil reservoir,and to have enumerated some successful examples.We hope to have some uses with others exploration.
