Drilling Fluid Technology for Drilling the Slim Hole Horizontal Shale Oil Well Shuaye-3-7HF

  • 摘要: 帅页3-7HF井是部署于苏北溱潼区块的一口页岩油Φ 118 mm小井眼侧钻水平井。在施工过程中面临着页岩地层井壁失稳、小井眼环空压耗大,易于漏失、水平井降摩减阻要求高、CO2污染等诸多难题。通过研究,构建了页岩水基钻井液体系SM-ShaleMud-II。室内评价表明,该体系具有优异的抑制能力、封堵性能和润滑性能,能够满足苏北页岩油长水平井对钻井液性能的要求。现场试验表明,页岩水基钻井液体系高温高压滤失量小于7 mL,体系黏附系数小于0.07,完钻起钻摩阻小于16 t,有效保持了阜二段页岩储层井壁稳定达110 h,改变水基钻井液对阜二段浸泡时间的认知。该井创页岩地层Φ118 mm小井眼裸眼段1948.66 m最长,水平段1361.66 m最长等多项记录,其施工经验可为后续超小井眼长水平井施工提供参考,也为页岩水基钻井液SM-ShaleMud-II在苏北页岩油大规模应用奠定了基础。
