中文摘要:
      以地沟油为原料制备的生物柴油为润滑剂的基础油, 以山梨醇酐单油酸酯(SP-80)、 聚氧乙烯辛基苯酚醚-10(OP-10)、 聚合型乳化剂聚氧乙烯(30)二聚羟基硬脂酸酯(简称 ARLACEL-P135)等为稳定剂, 通过探讨HLB值 (由 SP-80、 OP-10复配比决定) 和 ARLACEL-P135加量对乳状液稳定性的影响, 制备了一种环境友好的水基钻井液用油包水型润滑剂 SWR-2(配方为生物柴油+2.25%SP-80+0.25%OP-10+0.18%ARLACEL-P135+水, 油水比 6∶4), 评价了 SWR-2在基浆和钻井液中的润滑性能。研究结果表明: SWR-2具有优良的润滑性, 在基浆中添加 0.5%即可降低润滑系数 80%以上, 可抗 180℃高温, 且具有一定抗盐能力, 与水基钻井液配伍性良好。图 5表 5参 11
英文摘要:
      Using waste cooking oil preparing biodiesel as basic oil and sorbitan monooleate(SP-80),alkylphenols polyoxyethylene (OP-10),PEG-30 dipolyhydroxystearate(ARLACEL-P135)as stabilizers,A environment-friendly lubricant,SWR-2,composed of biodiesel +2.25% SP-80+0.25% OP-10+0.18% ARLACEL-P135,at oil-water ratio of 6∶4,was prepared through probing the effect of HLB value and the ARLACEL-P135 dosage on the stability of the emulsion,and the lubricating property of SWR-2 was evaluated in the bentonite muds and drilling fluid. The result showed that the SWR-2 had outstanding lubricating property. The lubricating factor could be decreased above 80% after adding 0.5% SWR-2 into bentonite slurry,and it could maintain good lubricating property at high temperature(180℃) . SWR-2 also was resistant to NaCl to some degree and could be used in various water-based drilling fluids.
