| 摘 要： | 镇泾长8为致密超低渗油藏,储层裂缝发育,通过野外露头调查、岩心观察、测井等手段对其裂缝产状、发育特征描述表明,长8发育一套高角度构造缝和成岩缝,裂缝走向NE组系为主.在此基础上,分析不同手段下裂缝识别的机理,通过岩心、成像测井标定常规测井,建立常规测井裂缝识别方法和标准,进而明确岩性、岩层厚度和断层为其控制因素.

| Abstract: | The Chang 8 reservoir in Zhengjing oilfield is ultra-low permeability reservoir and the reservoir fractures is developed.Based on the research of outcrop and core observation,well log exploration analyzes crack occurrence and the development characteristics of the fractures.The results show that a set of high-dip structural fractures and diagenetic fissure are developed in the Chang 8 reservoir.The strike of fracture is about NE.With the result,this article discusses fracture identification mechanism in various means and use the research of core, fracture in details to elaborate conventional logs and established recognition and method standard of conventional logs.Then it determines lithology,strata thickness and control factors. |
