所谓压井,主要指的是利用泥浆的重量所形成的液柱压力,克服井下地层压力的技术措施,作用在于对井下地层油气压力进行有效控制,以防地层流体进入井眼。本文首先指出了几种常规的压井方式及压井作业中应注意的问题,其次,对油田井下作业压井方式进行了分析。 The so-called kill, mainly refers to the use of slurry pressure formed by liquid column pressure to overcome the underground formation pressure technical measures, the role of underground oil and gas pressure in the formation of effective control to prevent formation fluids into the wellbore. This paper first points out several common ways of well killing and the problems that should be paid attention to in the well killing work. Secondly, the ways of downhole operation of the oil well are analyzed.
