摘要
在岩心钻探中,常常要用水下灌注水泥的方法来护壁、堵漏、封孔、处理井故。对水下灌注的方法和步骤进行了探讨,对水下灌注失败和事故的原因进行了分析,并提出了相应的解决办法。
In coring drilling, under-water cement grouting was often used for wall protection, leakage blocking, borehole sealing and downhole accident treatment. The paper discussed the technology and the procedures, analyzed the causes of grouting failure and put forward the solutions.
