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。
With the improvement of exploration level, fractured reservoirs will occupy a larger proportion of newly-added reserves, and research on reservoir fractures has been paid more and more attention. On the basis of a large number of literature research, this paper studies the present situation and existing problems of reservoir fracture description at home and abroad, and analyzes the description of similar reservoir outcrop description, core microscopic observation and artificial fracturing experiment. Technical methods, a brief summary of the characteristics of reservoir fractures, causes and the impact of late development of water.
