Development and Working Mechanism of Flow Pattern Enhancer for Synthetic Base Drilling Fluids

  • 摘要: 合成了一种可解决低温条件下合成基钻井液流变性问题的流型调节剂,测定流型调节剂对油包水乳状液流变性的影响,对比分析流型调节剂、有机土样品的红外特征和XRD特征,使用冷冻扫描电镜和透射电镜观察流型调节剂对乳液微观结构的影响,分析流型调节剂的作用机制,进行在高密度合成基钻井液中适用性评价。结果表明:流型调节剂能够显著改善合成基钻井液的低温流变性,有利于乳液稳定;流型调节剂吸附在油水界面,降低乳滴与有机土之间结构力,改善有机土颗粒与乳状液滴之间的相互作用,从而稳定油包水乳液的切力。与传统合成基钻井液相比,恒定流变的合成基钻井液具有更加稳定的低温流变性,保证井下安全。
