The Development and Properties of an Environmentally Friendly Metal Friction Reducer for Coiled Tubing

  • 摘要: 针对水平井长水平段连续油管作业过程中的锁定问题,采用改性植物油、表面活性剂、乙二醇作为核心主剂,制备了水包油型环保金属减摩剂。考察了该金属减摩剂在不同加量、矿化度、pH值和温度条件下对N80、P110、Cr-13钢块摩擦系数(CoF)的影响规律,同时采用MTT实验和动物实验评价了金属减阻剂的环保性能。结果表明,金属减摩剂加量为0.5%时,减摩效果最明显,使N80钢块的CoF降低至0.12(清水对应的CoF为0.42),CoF降低率达到71.4%;使P110钢块的CoF降低至0.16(清水对应的CoF为0.475),CoF降低率达到66.3%;使Cr-13钢块的CoF降低至0.115(清水对应的CoF为0.75),CoF降低率达到84.7%。金属减摩剂耐温达到140℃,适用pH值范围为1~10,耐矿化度达到30 000 mg/L。金属减摩剂细胞增殖率在95%~150%之间,半致死浓度LC50约为55 000 mg/L,无细胞毒性和动物毒性。研制的环保型金属减摩剂具有优异的减摩性能,满足连续油管现场作业要求。
