Analysis on the Feasibility of Reducing Drilling Fluid Density with Silicate Drilling Fluid in Drilling Unstable Formations

  • 摘要: 珠江口盆地古近系地层在钻井过程中,多口井出现坍塌、卡钻、起下钻遇阻等井壁失稳问题,现场通过增加钻井密度解决垮塌问题,但又出现压差卡钻、钻井时效低的问题。从黏土矿物含量分析、扫描电镜、滚动回收率及膨胀性实验入手,分析珠江口盆地古近系地层井壁失稳原因。古近系地层为微裂缝发育,在钻井过程中井壁周围应力发生变化及钻井液侵入,引起井壁坍塌,继而出现卡钻、起下钻遇阻等问题。为了解决以上问题,结合硅酸盐钻井液抑制性强、封堵性好、可增强岩石强度的特点,降低地层坍塌压力。对硅酸盐水基防塌钻井液进行优化及性能评价,结果表明,其性能参数满足钻井要求,具有提高岩石内聚力、抗压能力的特点,同时与古近系已用PLUS-KCl钻井液、油基钻井液相比,优化的硅酸盐水基防塌钻井液浸泡后岩石具有抗压强度高、内聚力高等特点,其内聚力高达11.7 MPa,是PLUS-KCl钻井液的1.9倍,是油基钻井液的1.5倍,可见在保证井壁稳定的前提下,用硅酸盐钻井液降低地层坍塌压力是可行的。
