在处理粘卡卡钻的事故当中,往往采用泡油、降低钻井液密度,甚至最后不得不进行套铣等方法,这些方法都或多或少的要改变了钻井液的性能才能实现,这样就造成了事故处理时间长,费用高,污染环境等等。使用封隔器解除粘卡卡钻在不改变钻井液密度和性能的前提下,有控制的降低地层和被粘卡井段之间的压差,达到最快解除粘卡卡钻为目的。
In the handling of stick-stuck accidents, it is often the practice to use bubbling to reduce the density of the drilling fluid, and finally to have to perform methods such as sleeve milling, all of which have more or less changed the performance of the drilling fluid. Accident processing caused a long time, high cost, pollute the environment and so on. Using a packer to disassemble a sticky card Drill Without a change in the density and performance of the drilling fluid, there is a controlled lowering of the pressure difference between the formation and the section to be stuck, to achieve the fastest release of a sticky card.
