摘要
针对江苏油田花庄地区钻井过程中井壁不稳、钻井液滤失以及低压、低渗、强水敏性油藏容易伤害等情况,研究并应用了超低渗透钻井液。室内试验及现场应用表明,超低渗透钻井液具有很好的封堵能力,通过增强内滤饼封堵强度大幅度提高岩心承压能力,达到降低滤失和保护储层的目的。
Based on the reservoir features in Jiangsu Hua-zhuang area,such as unstable sidewall,drilling fluid filtration,and the low pressure,low permeability and strong water sensitivi-ty,the ultra - low permeability drilling fluid was developed.Labo-ratory experiment and field application showed that the ultra - low permeability drilling fluid had better shut - off capacity,could in-crease core pressured capacity,achieve the goal of reducing filter loss and protecting reservoir.
