摘要: 通过对金湖凹陷天长地区30余口井的岩心进行铸体薄片、阴极发光、包裹体、扫描电镜、X-衍射粘土矿物等分析化验、统计,把研究区储层分为四大类七个亚类,认为本区低渗透储层的主要控制因素有沉积相带、碳酸盐含量、泥质含量、粒度中值等,对于东部的Ⅱc、Ⅲ类储层,压裂和重复压裂是获得工业油流的主要对策。

Abstract: On the basis of moldic pore section, cathodoluminescence,enlosure, scanning electron microscope, x-ray diffraction for clay mineral, assay and statistics of bore specimen of over 30 wells in Tian-Chang region of Jin-Hu sag, the reservoir in the region of interest is divided into 3 kinds of patterns and 7 subdivisions. It is thought that main controlled factors of low permeability reservoir are zone of deposition, carbonate content shale content, granul-arity median and so on. Therefore, fracturing and refracturing are main methods of obtaining commercial oil and gas forⅡc andⅢpatterns of reservoir in the East part of Jin-hu sag.

Key words: Jin-hu sag, core analysis, low permeability reservoir, fracturing
