摘要: 针对巴什托超高压裂缝性油藏在开发过程中出现的含水上升快、产量下降快、底水能量弱等特点,在精细地质研究的基础上,对储层特征和油井见水规律进行了研究,建立了5种油井见水模式,对油藏实施的转抽、堵水、提液等措施进行了总结分析,为下一步提高开发效果提出了切实可行的技术方案。Abstract: In accordance with the characteristics of fast water flooding,production decline andtom water energy in Bashituo overpressured,fractured reservoirs,detail geological study wasweak bot-carried outandFiveunderstandings weregained about reservoir fracture development and oil and water movement.modes of water floodingwere proposed.Implementation results of water pump,turn,solutionmeaSureSfor thereservoir weresummarized and the plan for improving development was proposed.
