摘要: 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。

Abstract: The Xiazijie Formation oil pool in Xiaoguai oilfield is a low-porosity, extreme-low permeability, fractured conglomerate reservoir. Based on detailed geological reservoir description and production performance data, the authors investigate the factors influencing the production of the oil pool with CMG’s black oil model (IMEX) . Variation and sensitivity of such factors as IPR, location of water injection, production rate, well pattern,direction of well array in relation to fracture orientation and recovery method ( solution gas drive vs. water injection) are analyzed.

Key words: fractured reservoir, waterflooding, numerical simulation, recovery efficiency
