| 摘 要： | 常规的钻井液提切剂（如HV-CMC、HEC等）已不能满足无固相钻井液新体系性能和环保要求，使用后存在潜在的环境污染风险，为此，以生物聚合物为主要原料，采用表面活性剂活化、复合等工艺制备得到了一种新型弱凝胶提切剂。进行了新型提切剂的性能评价和作用机理研究，并在塔里木轮南油田进行了成功应用。试验结果表明，新型提切剂具有优良的抗盐、抗温性能和高剪切速率黏度（在0.3 r/min的剪切速率下，黏度达90 000 mPa·s以上），携岩能力强，可生物降解，无毒，满足了钻井工程要求和环保要求。

| Abstract: | Conventional shear strength improving agents(such as HV-CMC and HEC)can not meet the need of solids-free drilling fluids and environmental protection, due to their potential environmental pollution. Focusing on these issues, the biopolymer was used in this paper as the major material, the novel weakly gelled shear strength improving agent was developed after activating, compounding, and other technology in surfactants. The working mechanism and performance of the novel weakly gelled shear strength improving... |
