摘要
胡状集油田胡十二块经过近１０年的注水开发，储层的性质已发生了很大的变化。本文以注水开发前后相邻两口取心井（胡１２－２０和胡检１井）为研究“窗口”，从储层物性、层内及层间非均质性和储层微观孔隙结构等４个方面来阐明本区储层的动态变化特征，从而为提高开发效果提供重要的地质依据。
Reservoir properties have greatly changed in No.12 fault block, Huzhuangji oilfield after the oilfield has been developed by waterflooding for about ten years. In this paper,two adjacent cored wells (Hu12 20 and HJ1),drilled at the pre and post waterflooding, are selected as “research window”. Dynamic variation of reservoir is explained from the view of point of reservoir physical properties, intraformational and interlayer heterogeneities and reservoir micropore structure, which will provide important geological basis for improving oilfield development effect.
