摘要

摘要: 中国东部深层油藏隔层由于其破裂压力小, 受地静压力、构造应力的作用而形成裂缝, 降低了其封闭性, 从而影响油田注水开发的效果.以冀东油田高尚堡Es₃²⁺³油藏为例, 综合地质、地震、测井和生产动态资料, 应用一系列先进技术, 对我国东部深层油藏隔层裂缝的基本特征、分布规律进行了深入的研究, 分析了隔层裂缝的形成原因及其对注水开发的影响, 并提出了解决措施.

Abstract: Insulating layer of deep reservoirs in eastern China involves a large number of fractures because of its low breakdown pressure and high effective stress loaded, and as a result, its sealing capability is decreased. Taking the Gaoshangpu Es₃²⁺³ Member reservoir as an example, this paper studies its basic characteristics and distribution law of the fractures in the deep reservoir, analyzes their origin and effect on water-flooding, and offers corresponding solutions. Research of insulating fractures is very important for reservoir dynamic analysis and improving water-flooding level.
