辛176断块沙四段油水层测井响应电阻率相当,存在低阻现象,制约了断块的勘探开发。为对低阻油藏进行识别,从储层特征和四性关系研究出发,通过岩心观察,岩心分析化验、录井等资料分析研究和室内试验等手段对低阻油藏成因机理进行了研究,明确了沙四段低阻成因控制因素,为沙四段低阻油藏识别机理和勘探开发奠定了基础。
The logging resistivity of Shahejie Formation of Shahejie Formation in Xin 176 fault block is quite low, which presents the phenomenon of low resistance, restricting the exploration and development of fault blocks. In order to identify low-resistivity reservoirs, starting from the reservoir characteristics and the relationship between the four nature, through the core observation, core analysis, logging data analysis and laboratory tests and other means to study the genetic mechanism of low-resistance reservoirs, The control factors of the low resistivity formation in the fourth member of Shahejiedu are clearly defined, which lays the foundation for the recognition mechanism and exploration and development of the low resistivity reservoir in Shahejie four.
