摘要
介绍了聚合醇钻井液体系的室内研究和现场应用 ,该体系具有优良的页岩抑制性、润滑等优越性 ,现场应用于文 38— 4 3井和水平一井 ,该体系可大大降低摩阻 ,保护油气层 ,解决强水敏地层的稳定等复杂情况。该体系是油基钻井液体系的优良替代品 。
The laboratory study and field application of new type polyalcohol drillig fluid system is presented in detail in this paper.The system exhibits good shale-inhibitive and lubricity.Through field application in well Wen38-43 and Deviated Hole No.1,the results show the system can decrease the friction;protect oil gas layer and can settle the stability problem of strong water-sensitivity formation.The system is a good alternative of oil-base drilling fluid system and it is suited for directional drilling.
