惠民凹陷临南斜坡带资源评价及勘探潜力研究

为了探讨惠民凹陷临南斜坡带的勘探前景，在综合分析储储层分布和断层在成藏中作用的基础上，对圈闭及其资源量进行了评价。全区的排烃量，聚集量分析结果表明，中央背斜带和商河构造高带石油探明储量的比例较高，而位于临南斜坡带的江家店－曲堤，临南－钱官屯地区的探明比例分别只有26％和18％，这两个地我仍有较大的勘探潜力。文章还分层系分析了夏口断裂带砂体发育及成藏条件，确定江家店，钱官屯地区为有利的勘探目标区。

Resource evaluation and exploration potential on Linnan slope belt

To discuss the exploration prospect of Linnan slope belt in Huinin sag, in this paper the content of hydrocarbon generation and hydrocarbon expulsion of Linnan subsag are evaluated from the hydrocarbon source rocks. Abnormal pressure distribution and structural background control the quality of oil?gas accumulation of various plays. The traps are evaluated based on synthetical analyses of the reservoir distribution and action of the faults on reservoir action. By the analyse results of the hydrocarbon expulsion content and accumulation quantity of the whole area, the proportion of petroleum proven reserves in the central anticlinal belt and Shanghe structural belt is relatively high, while that in Jiangjiadian?Qudi and Linnan?Qianguantun area is only 26% and 18% ,respectively, so the latter two still have considerable exploration potential. It is determined that Jiangjiadian and Qianguantun areas are the favorable exploration target areas from the analysis of the development and reservoir conditions of Xiakou fracture belt sandbody according to the series of strata.
