摘要

中原油田云3 块油藏为低孔、低渗透、油水关系复杂的复杂断块油藏。为了改善开发效果,应用数值模拟结果,紧密结合油藏精细描述和油藏工程结果,研究了该油藏合理的开发技术政策。在历史拟合修正地质模型的基础上,对目前的油田的水淹状况作了分析,并且制定了相应的调整方案。研究结果表明,该油藏目前主力油层的动用程度较低,剩余地质储量丰富,应加大采油速度生产,并提出了改善注水产液结构的调整方案。

Abstract

Yun 3 reservoir has low porosity and permeability and

complicated oil2water relationship. In order to improve the

production effect ,with the application of reservoir numerical

simulation , combined with reservoir fine description and

reservoir engineering technique , the reasonable exploitation

policy has been studied. On the basis of the geological model

that has been modified by history matching ,current water2

flooded extent of layers is analyzed and responding

adjustment plans are established. The results show that the

main production layers have abundant remaining reserve and

ought to be produced at a high oil productive rate. Plan F3 is

designed to improve water injection and productive liquid rate

and is recommended to employ.
