摘　　要：为了解决钻头泥包难题以提高深井钻探效率,采用胶束共聚法合成了一种新型的水基润滑剂。研究了单体配比、引发剂浓度和聚合时间对水基润滑剂的润滑性能的影响。研究结果表明,该水基润滑剂的最佳合成条件为丙烯酰胺、α-烯烃磺酸钠和三羟乙基烯丙基氯化铵的最佳摩尔比为1:1:6,引发剂过硫酸铵的加量为0.3%,聚合时间为3h。当水基润滑剂加量为2.0%时,具有较好的防泥包效果,且在渤钻土中的润滑系数降低率达到70%以上。该水基润滑剂具有典型的低分子量结构,在现场浆中对模拟钻头(钨钢棒)具有显著的防泥包效果,在放大实验中具有稳定的可重复性能,具有潜在的实际现场应用价值。To solve the problem of bit balling and improve the efficiency of deep well drilling,a novel water-based lubricant with low molecular weight was synthesized by micellar copolymerization.The effects of monomer ratio,initiator concentration and reaction time on the lubrication performance were studied.The results showed that the optimal synthesis conditions were 1:1:6(mole ratio) of acrylamide:α-olefin sodium sulfonate:trihydroxyethyl allyl ammonium chloride,0.3% of initiator ammonium persulfate,and 3 h of reaction time.The water-based lubricant(2.0%) had a good anti-mud coating effect,and the lubrication coefficient reduction rate could reach 70% in Bohai drilling soil.The water-based lubricant was a typical low molecular weight structure and had a significant anti-mud effect on the simulated drill bit(tungsten steel bar) in the field slurry.Moreover,the synthesis conditions of water-based lubricant were repeatable in the amplification experiment,which demonstrated their potential use in field practice.
