Low Temperature Rheology of Clay-free Seawater Base Drilling Fluids

  • 摘要: 针对海洋深水钻井作业所遇到的水基钻井液低温增稠问题,在全面分析低温增稠机理基础上,利用实验室自制的深水钻井液模拟装置,通过优选处理剂,构建了一套具有好的低温流变性的无黏土相海水基钻井液体系。实验结果表明,该钻井液体系经130℃老化后,低温流变性好,老化前后4℃和25℃时的表观黏度之比分别为1.179、1.250,塑性黏度之比分别为1.167、1.240,动切力之比为1.200、1.265,静切力稳定,动塑比变化范围在0.625~0.694 Pa/(mPa·s)之间,API中压滤失量在9.0 mL左右;润滑系数为0.181,页岩水化膨胀率为10.0%,页岩热滚回收率为87.0%,同时具有较强的储层保护能力和较好的抑制天然气水合物生成能力。
