摘要
当进行钻井工程作业时,经常遇到许多突发的情况,其中井漏就是比较严重的一种情况.钻遇漏失层发生井漏会使钻井液流体进入到地层,不仅使地层会受到污染,也会产生井底压力与地层压力的失衡发生井喷及井喷失控事故.同时,为了弥补井漏带来的损害需要花费大量的财力、物力和人力.因此,加强预防钻井工程中的井漏现象以及研究堵漏技术有着十分重要的作用和意义.
When drilling engineering operations,there are often many unexpected situations,of which the leak is a serious situation.Drilling in the leakage layer causes the drilling fluid to enter the formation,which not only causes the formation to be polluted,but also causes an imbalance between the bottomhole pressure and the formation pressure to cause blowout and blowout out of control accidents.At the same time,it takes a lot of financial,material and manpower to make up for the damage caused by the lost circulation.Therefore,it is of great significance and significance to strengthen the prevention of well leakage in drilling engineering and to study plugging technology.
