摘要:
以安塞油田长6特低渗微裂缝性油藏为例,围绕开发中后期储层特征、水驱油机理的分析,结合矿场试验效果,提出了特低渗微裂缝性油藏周期性注水的开发模式,以提高采收率。并针对周期性注水适用条件、注水时机选择、合理配注量及注水周期等问题进行深入分析,提出相对合理的计算方法,为特低渗微裂缝性油藏中后期合理注水参数调整提供了理论与实践依据。
Abstract:
The periodic water injection exploitation model for ultralow permeability reservoirs with microfissures is presented, based on analysis on architecture of reservoir, characteristics of water injection and waterflood displacement practice of the Chang 6 oilpool reservoir which is in its middlelate exploitation period, from Ansai Oil Field, Ordos basin, and on mechanism of wateroil displacement. The reasonable injection parameters such as injection volume, injection period, suitable periodic injection moment for a typical well group in the study area is also elucidated, after consideration of applicable periodic injection conditions, suitable water injection time, injection period, wettability and developed microfissures of the Chang 6 reservoir, residual hydrocarbons and energy in the formation, and waterflood exploitation phase. The research result may have theoretical and practical significance for adjusting injection and exploitation policy in middlelate development phase for ultralow permeability reservoirs with microfissures both in Ordos basin and in other hydrocarbonbearing basins.
