摘要
塔里木油田储集空间多样,以孔、洞、缝为基础的不同类型储层以不同形式组合,形成了以缝洞型储层为主的非均质性特强的碳酸盐岩油气藏,此类油气藏描述工作难度极大,相关基础研究不能满足油田开发的需要,加上传统数值模拟软件的限制,对应的油气藏数值模拟技术已经严重制约了油田的高效开发。塔里木油田塔中62井区采用国际公认的GOCAD建模软件和斯坦福大学开发的GPRS数值模拟计算器,在离散裂缝模型的基础上结合MSR方法,建立了相关的储层地质模型并进行了动态验证,为进一步认识塔里木油田碳酸盐岩油气藏缝洞分布规律、连通性及油水分布关系提供了有效手段。
Tarim oil field space varied.The reservoir is combined into different forms based on mainly pore,dissolved cavern and fracture.The strong heterogeneity carbonate reservoir is formed by fractured-vuggy reservoirs.This kind of reservoir is different to describe,then related research can't meet the requirements of oilfield development,and there is the limitation of the traditional numerical simulation software,so the corresponding reservoir numerical simulation technology has seriously limited the efficient development of oil field.Internationally recognized GOCAD and GPRS developed at Stanford University are used in Tazhong 62 of Tarim oil field.Multiple Subregion method is combined with Discrete Fracture Network Model,then the reservoir geologic model is built and dynamic verified.All those provide effective means to research on fractured-vuggy distribution,connectivity and oil-water distribution in Tarim oil field.
