摘要
为了解红沟子构造裂缝类型、特征及其控制因素。在岩心裂缝观察基础上,运用常规测井和成像测井资料进行裂缝识别,描述了裂缝的类型和特征,探讨了裂缝的分布规律及其控制因素。研究区发育构造裂缝、滑塌裂缝和溶蚀裂缝,以构造裂缝为主;在缺少成像测井资料的井段,通过利用常规曲线资料计算新参数曲线来进行裂缝识别;裂缝发育受岩性、构造、沉积环境等多种因素控制。研究区东部上干柴沟组裂缝极为发育,应为有利勘探目标。
To understand the types,characteristics,and control factors of the fractures in Hongzougzi Structure,based on the data from descriptions of the core and fractures,the conventional and imaging logging data were used to denote the fracture types and characteristics,and its distribution law and major control factors were discussed. In the studied area there developed structural fractures slump and dissolved fractures,structural fractures were dominated,in the interval where lacked imaging logging fractures were recognized by calculating new parameters with conventional logging curves,the development of fractures was influenced by multi-factors,such as lithology,structure and sedimentary environment. Fractures are the mostly developed in the east of the upper Gancaigou Formation,it is the favorable exploration target zone.
