油气储层裂缝描述综述

An Overview of Fracture Description for Oil and Gas Reservoirs

随着勘探程度的提高,裂缝型油气藏在新增储量中将会占有更大的比重,储层裂缝的研究日益受到重视。在大量文献调研的基础上,研究了国内外关于储层裂缝描述研究的现状以及存在的问题,分析论述了相似露头区描述、岩心镜下观测、人工压裂实验等目前储层裂缝描述的主要技术方法,简要总结了储层裂缝的特征分类、成因以及对后期开发注水的影响。

Fractured reservoirs occupy a greater proportion with the progress of oil and gas exploration and development.More attention will be paid on fracture research.The correct description of reservoir fractures is the key point for highly efficient development of fractured reservoirs.In this paper,based on literature research,present status and existing problems of reservoir fracture description at home and abroad were discussed,main technical methods of fracture description were analyzed,origin and feature classification of reservoir fractures were also researched.
