摘　　要：构造裂缝是裂缝性油藏的主要储集空间和渗流通道,对裂缝网络的描述是裂缝性油藏地质研究的重点和难点。裂缝网络发育受多种因素影响,非均质性极强,结合理论模式,通过野外相似露头,以及胜利油区富台油田车古201潜山油藏的钻井、测井、岩心、分析化验等多种资料、信息,系统研究了大、中、小、微不同尺度裂缝的发育特征及其分布规律,定量确定了不同尺度裂缝的关键特征参数,在此基础上针对背斜潜山不同构造部位(背斜轴部、翼部、倾末端),建立了背斜构造裂缝性油藏裂缝网络发育模式,为准确把握裂缝性油藏裂缝分布规律及高效部署开发井提供地质保障和依据。Tectonic fracture is the main reservoir space and percolation path in fractured reservoir,and how to describe the fracture network is important and difficult for geologic research of fractured reservoir.Many elements control fracture network development which is highly anisotropic.Using similar field outcrop and drilling,logging,core,analyses and testing etc.of Chegu201 of Futai buried hill reservoir in Shengli oilfield,we systematically studied the development feature and distribution rule of different scale.Based on quantitative ascertaining of key characteristic parameters of different fracture scale,fracture network pattern of different tectonic position such as anticlinal axis,anticlinal edge,the fracture development mode of anticline fractured reservoir is constructed,and therefore offering the geologic reference and foundation for understanding distribution rule of fractured reservoir,as well as the well exploration well deployment.
