    摘要:

    四川盆地西南缘油气资源潜力丰富,但地质构造复杂,邻井资料缺乏,钻探施工难度大。川马页1井是部署在川西南五指山构造带西翼的一口页岩气地质调查参数井,该井设计井深3400 m,实际完钻井深3635 m,在实钻中钻进至3437.58 m时因井内复杂采取了暂闭封井,并从2818 m侧钻至完钻井深。针对钻井难点,总结形成了大直径井眼小落鱼事故处理、长裸眼井段大口径高效快速钻进、复杂地层裸眼侧钻、硅钾基聚合物防塌钻井液体系等多项钻井关键技术,解决了生产实际难题,保障了地质目的,取得了显著应用效果,可为同区域类似钻探工程施工提供借鉴,支撑新一轮找矿突破战略行动。

    Abstract:

    The potential of oil and gas resources in southwestern margin of the Sichuan Basin is abundant, however the geological structure is complex and lack of adjacent well data, making difficult drilling construction. Well Chuanmaye 1 is a shale gas geological survey parameter well deployed in the west wing of the Wuzhishan structural belt in southwest Sichuan. The designed depth of the well is 3400m, and the actual completed drilling depth is 3635m. A temporary closure was adopted when drilling to 3437.58m due to the complexity, and side tracking was carried out from 2818m to the completed drilling depth. In response to drilling difficulties, multiple key drilling technologies are summarized, including the handling of small fish accidents in large-diameter boreholes, efficient and rapid drilling with long open holes and large diameters, open hole side tracking in complex formations, and silicon potassium based polymer anti-sloughing drilling fluid systems. These technologies solved the practical problems, ensured the geological objectives, and achieved significant application effects, which can provide reference for similar drilling projects in the same region and support the new round of strategic action for prospecting breakthrough.
