摘要(Abstract):
通过电成像扫描图像及岩心扫描图片对比分析,识别火成岩的结构、构造,共识别6种火成岩结构,区分6种火成岩构造。火成岩结构和火成岩构造识别后,与常规测井资料结合,实现了火成岩储层岩性的精细划分。利用电成像测井资料识别储层裂缝与孔洞,同时对裂缝参数进行定量计算,为测井解释提供了更多、更精确的储层信息,提高了储层测井解释评价的水平和解释符合率。
Through the comparing and analyzing the scanned pictures of electrical imaging and core,the texture and structure of igneous rock can be identified.There are 6 kinds of identified igneous rock texture and structure.And then combining with conventional well logging data,the fine division of reservoir lithology of igneous rock can be realized. With the help of the data of electrical imaging logging,reservoir fractures and pores can be recognized,and at the same time the quantitative calculation of fracture parameters can be done,so more and even accurate reservoir information can be provided for well logging interpretation and in the end the level and coincidence of logging interpretation can be enhanced greatly.
