低渗透油田开发效果评价指标——以张天渠油田为例

EVALUATION INDICES OF DEVELOPMENT EFFECT FOR LOW PERMEABILITY OIL FIELD TAKING ZHANGTIANQU RESERVOIR AS AN EXAMPLE

低渗透油田在世界上储量占有相当大的比例,在我国也广泛分布,其中鄂尔多斯南部中生界是低渗透油田集中发育的地区之一。对于这类非常规储层低渗透油田开发效果评价,需要有一套规范的评价指标体系,以利于总结这类油田的研究成果,指导油田下一步调整挖潜。本文以张天渠油田为例,提出低渗透油田7类10项开发效果评价指标,可供低渗透油田开发动态分析时参考,为国内外开发同类性质的油田提供经验。

Low permeability oil field is distributed widely in the world and China, and the south of Ordos basin is one of the regions where low permeability oil fields concentrate. It needs a set of formal evaluation index system for this kind of unconventional low permeability reservoir development. It is useful for summarizing the experiences of these oil fields and steering the research of adjustment and augment oil reserves. A case of Zhangtianqu reservoir provides 7 sets and 10 indices for evaluation development effect. It will benefit developing low permeability oil fields and those similar reservoirs in our country and overseas.
