防喷器控制装置三位四通转阀手柄位置分析

Analysis of Four-way Valve Handle Position on BOP Control System

在正常钻井过程中,防喷器控制装置的三位四通转阀手柄是置于中位,还是和防喷器保持一致的开位或关位,一直是国内井控管理人员争论的话题。通过对国内外行业标准的对比、防喷器控制装置及三位四通转阀工作原理的分析,阐明了转阀手柄位置应和防喷器开、关位置保持一致的必要性。为防喷器控制装置在井控中的安全使用提供理论依据。

In normal drilling process, whether the four--way valve position on BOP control system should be remained in the middle or kept up with BOP device has been all the time a controversial topic argued by domestic well control administrators. Through the comparison of domestic and in- ternational industry standards, and the analysis of working principle of BOP control system and four--way valve, this article illustrates the necessity of the four--way valve handle position which should be kept up with the switch of BOP device,and further provide a theoretical basis for safety applications of BOP control system in the well control process.
