摘要
针对胜利油田某些区块的东营组高孔高渗储层具有较强的水敏性和速敏性的特点,研究开发了成膜强抑制纳米封堵钻井液体系。该体系具有强抑制性和成膜特性,能够最大程度地减轻储层伤害,有利于发现和保护油气层;多种防塌抑制剂的协同作用,有利于稳定井壁,减少复杂情况的发生,保证快速钻进和安全钻井,为胜利油田有效开发该类区块提供了有效保障。
A high inhibition film-forming nano-sealing drilling fluid is developed aiming at the water and rate sensitivity reservoirs of Dongying block Shengli oilfield.The drilling fluid system has some characteristics of high inhibition,filmforming,protecting reservoirs,and borehole stability,and it offers efficiency guarantee for the availability exploitation this kind of block in Shengli oilfield.
