在油气井的过程当中,为了在出现一些复杂多变的地层的时候能够很好的应对,保证在施工的过程中能够安全的完成钻井作业,所以就得十分细心的观察以便在溢流现象出现的时候能够第一时间的进行关井控制,然后就可以根据分流的程序对节流循环排出溢流,这样就会在地层平衡的情况下很好的进行钻井作业。本文就主要介绍了在油气井的勘探过程中的发生溢流的主要的原因以及主要监测的方法和预防的措施,对于油气井的关井分流程序也作了简单的分析。
In the process of oil and gas wells, in order to respond well to some complex and changeable formations and ensure the safe completion of drilling operations during the construction, we must observe them carefully so that when the overflow phenomenon occurs The first time to shut-in control, and then can be based on the shunt program discharge overflow throttling cycle, so that it will be well balanced in the case of well drilling. This paper mainly introduces the main reasons for overflow during the exploration of oil and gas wells and the main monitoring methods and preventive measures. It also makes a simple analysis of the shut-in and shunting procedures for oil and gas wells.
