研制和应用了具有稳定井眼和保护油层双重功能的复合离子型聚合物乳化钻井完井液体系。室内试验结果表明，这种体系具有优良的抑制能力、携岩能力和保护油层能力，能够顺利解决水平井钻具粘卡和岩屑床问题。实践证明，苏平１井平均井径扩大率为３．９％，井眼失稳时间为零，实际钻井液费用比设计降低５３．８％，技术经济效益显著
The composite ion polymer emulsion drilling and completion fluid system with the dual functions of stable wellbore and protective reservoir has been developed and applied. The results of laboratory tests show that this system has excellent ability of inhibiting, carrying capacity of rocks and protecting oil reservoir ability, and can successfully solve the problems of horizontal well drilling tools sticking cards and cuttings bed. Practice has shown that the average diameter expansion of Suping 1 well bore rate was 3.9%, wellbore instability time is zero, the actual drilling fluid costs lower than the design 53.8%, significant technical and economic benefits
