沈84-安12块特高含水期提液技术研究与应用

Research on ultra-high water cut state fluid lifting technology and its application in Shen 84-An 12 block

摘要: 辽河油田沈84-安12块进入特高含水开发期,油藏剩余可采储量丰富,地层能量充足,储层物性较好,而区块常规措施措施效果差。在对提液可行性充分论证的基础上,通过对剩余油潜力分析,实施了以提液为主的水动力调整,区块开发效果得到了明显改善。区块日产油水平增加189t,含水上升率由3.7%下降为0,自然递减率由15.66%下降为4.81%,实现了区块特高含水期的高效开发。

Abstract: Liaohe oilfield Shen 84-An 12 block enters ultra high water cut stage,residual reservoir is rich,formation energy is sufficient.Formation physical property is good,while bock conventional measure has bad effect.Based on fully testified fluid lifting feasibility,through the analysis of residual oil potential,hydrodynamic adjustment mainly fluid lifting is implemented,block development effect improves significantly.Block daily oil production increase 189t,water cut down from 3.7% to zero.Natural decline from 15.66% to 4.81%,which realized high efficiency development of block in the ultra high water cut stage.
