摘要
HD10-1-4HF双分支水平井位于塔里木盆地满加尔凹陷北部哈得逊构造带哈得1号构造,为提高钻井液润滑性,减少钻分支水平井段过程中的托压、卡钻等复杂问题,使用了抗磨减阻剂KMJ-1。抗磨减阻剂KMJ-1主要通过其组分中的成膜润滑材料和抗磨增效材料吸附沉积在钻具和泥饼上,形成一层高效耐磨的润滑膜,来降低钻具和套管之间、钻具和泥饼之间的摩擦阻力,发挥高效的润滑作用。室内评价和现场实际应用结果表明,抗磨减阻润滑剂KMJ-1用量少、润滑性好,加量为1.0%时即可将欠饱和盐水聚磺钻井液的润滑系数降低85%,加量为1.5%时即可将泥饼黏附系数降低75%以上,且能使钻井液的抗磨承压能力提高5倍以上;对钻井液性能无不良影响;其可以降低钻进时的转盘扭矩,降低起下钻及接单根时钻具的摩阻,降低黏滑比,为该井的快速安全钻井施工提供了有效保障。
Well KMJ-1-4HF is a bi-lateral horizontal well located in the No.1 Hade Structure of the Hadexun tectonic zone in the north of Manjiaer trap in the Tarim Basin. High friction between drill string and borehole wall caused difficulties exerting weight on bit and pipe sticking. An anti-wear friction reducer KMJ-1 was used to solve these problems. KMJ-1 formed a tough lubricating film on both the surface of the borehole wall and drill string to reduce the frictions between them. KMJ-1 functioned at low concentration in drilling fluid, and greatly reduced drag and resistance to the moving of drilling strings and pipe sticking.
