小拐油田夏子街组油藏为低孔、超低渗裂缝性砾岩油藏，开发难度大。在地质三维精细油藏描述的基础上，充分利用现有生产动态资料，针对不同注采比、注水部位、注水方式及不同采油速度下的开采效果，合理井网及井排切割裂缝方向，不同开采方式（如溶解气驱、注水）下的采收率，裂缝参数敏感性分析及其对开发效果的影响程度等方面展开讨论，研究了深层裂缝性油藏注水开发的可行性，为该油藏的合理开发提供了较为充实的理论依据。
The Xiazihu Oilfield Xiazijie Formation reservoir is a low-porosity and ultra-low permeability fractured conglomerate reservoir, which is difficult to develop. Based on the description of the geological three-dimensional fine reservoir, the existing dynamic production data are fully utilized. According to the different mining and injection-production ratio, water injection site, water injection method and different oil recovery rates, the rational well pattern and well row fracture direction are different Mining methods (such as dissolved gas flooding, water injection) under the recovery rate, the sensitivity analysis of the fracture parameters and its impact on the development of the degree of discussion and other aspects of the deep fractured reservoir feasibility of water development for the oil The rational development of Tibet provides a more substantial theoretical basis.
