摘要
地下储层构型研究是提高油气采收率、最大限度地开发油气资源的关键所在,夹层的类型、特征及分布情况都对储层构型研究有着重要意义。本文通过总结夹层结构特征,在夹层岩性分类基础上,进一步将夹层分为斑状、条带(条纹)型和致密型,并总结各小类夹层测井曲线特征。在此分类基础上,从储层构型角度出发,根据夹层岩性、结构和测井曲线特征的不同,将夹层划分为三个级别,并研究每个级别夹层在储层构型界面识别中的意义。
Study on types, features and distribution of interlayers is of great significance to identifying reservoir architecture, which plays a key role in improving the oil and gas recovery and exploiting resources at utmost. In this paper, on the basis of interlayer lithological classification, by summarizing the characteristics of interlayer structure, interlayers were further divided into three types： porphyritic type, striped type and dense type. Their different logging curves responses were summarized. According to the different characteristics of lithology, structure and logging curves responses, the interlayers were divided into three levels from the angle of reservoir architecture in order to provide the basis in identifying reservoir architecture interfaces.
