冀承页1井小口径页岩油气调查井位于河北省承德市，构造位置为燕辽裂陷槽承德盆地宽城坳陷卢家沟向斜带，地质条件极为复杂，不仅存在涌水及漏失问题，且目的层段洪水庄组碳粉砂质页岩结构松散破碎，黏土矿物组成中蒙脱石含量高，水敏性强，井壁稳定性差。钻探施工存在易塌、易漏、易卡钻风险，对钻探工艺及冲洗液技术提出了较高的要求。针对该井的钻遇地层，细化分析各井段对冲洗液的性能需求，研发配制了冀承页1井专属冲洗液体系，并针对目的层页岩开展冲洗液配比正交实验，确定了目的层冲洗液配方：水+3% Na-B+3%（土重）Na2CO3+3% KHM+1% GPC+0.2% K-PAM+0.2% Na-CMC+1.5% MSDS，因地制宜地开展冲洗液维护措施，在实际钻探过程中取得了良好的应用效果，可为类似钻探工程冲洗液技术提供借鉴。
The Well Jichengye-1 is located in Chengde City， Hebei Province， which is a small-diameter shale oil and gas survey well， with a structural location in the Lujiagou syncline of the Kuancheng Depression in the Yanliao Rift Trough of the Chengde Basin. The geological condition of the drilling project is extremely complex， with not only water inflow and leakage problems， but also loose and fragmented carbon powder sandy shale in the Hongshuizhuang Formation of the target layer， high montmorillonite content in the clay mineral composition， strong water sensitivity， and poor wellbore stability. Drilling construction poses risks of collapse， leakage， and drill sticking， which puts high demands on drilling technology and flushing fluid technology. In view of this， a detailed analysis was conducted on the performance requirements of each well section for the flushing fluid in the encountered strata. A dedicated flushing fluid system for Well Jichengye-1 was developed and formulated. Orthogonal experiments were conducted on the flushing fluid ratio for the target shale layer， and the flushing fluid formula was determined as follows： water+3% Na-B+3%（soil weight） Na2CO3+3% KHM+1% GPC+0.2% K-PAM+0.2% Na-CMC+1.5% MSDS. Tailored flushing fluid maintenance measures were carried out， which has good application results in the actual drilling process， and can provide reference for similar drilling projects.
