Reservoir Fracture Identification Method Based on Well Logging Curves in Low⁃Permeability Sandstone Reservoirs in Qiuling Oilfield of Tuha
The low⁃permeability reservoir in Qiuling Oilfield of Tuha shows that the characteristics of early water discovery and rapid rise of water cut in some wells during water injection development, and dynamic analysis shows that there are dominant channels or the possibility of fractures in the reservoi...

| description | The low⁃permeability reservoir in Qiuling Oilfield of Tuha shows that the characteristics of early water discovery and rapid rise of water cut in some wells during water injection development, and dynamic analysis shows that there are dominant channels or the possibility of fractures in the reservoir. In order to further improve the development effect and enhance oil recovery, it is necessary to verify and determine the development of micro⁃fractures in the reservoir at the later stage of reservoir development. In this paper, based on the description of the core of a water washing inspection well, the development and distribution of reservoir fractures are studied, and a method of identifying the fracture development horizon based on logging curves are proposed. Through the analysis of logging data of two wells and the comparison of water absorption profiles, the method is proved to be feasible and reliable, and the study provides theoretical support for improving the development effect of water drive, effective utilization and recovery of remaining oil in Qiuling Oilfield of Tuha. |
