摘要
通过对杏子川油田化子坪区长6油层组岩心、测井及测试资料的统计分析,讨论了研究区长6储层宏观非均质性特征。研究表明,本区长6储层的层内、层间和平面非均质性均比较强,其变化规律主要受沉积相带控制。层内非均质性主要受沉积韵律和层内夹层影响;层间非均质性取决于物性非均质性参数、分层系数、砂岩密度和层间隔层展布;平面非均质性与砂体形态及接触关系密切相关,同时利用孔隙度、渗透率的空间分布分析研究储层平面非均质性。
Through analyzing the core,logging and testing materials of Chang 6 reservoir of Huaziping district of Xingzichuan oilfield,this paper discusses the characteristics of marco inhomogeneous medium.The results show that the property of inhomogeneous is very strong,and the changing rules are controlled by sedimentary facies. The property of inhomogeneous inside the layers are associated with the rhythm and interbed of it,and the property of it interlayers are associated with the parameter and coefficient and sandstone density.The flat inhomogeneous is associated with the sand and touching relationship.At the same time,the flat inhomogeneous is researched by analyzing porosity and permeability.
