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。
After nearly 10 years of waterflood development in the Huzhuangji Oilfield Hu 12, the nature of the reservoir has undergone great changes. In this paper, two adjacent coring wells (Hu 12-20 and Huqian 1) were used as the study window before and after the water injection development. From the aspects of reservoir physical property, intra-reservoir and inter-layer heterogeneity, and micro-pore structure in reservoirs To clarify the dynamic characteristics of the reservoir in this area, so as to provide an important geological basis for improving the development effect.
