Discussion on the Handle Position of Three Position Four Way Steering Valve on Remote Control Console of Well Control Equipment
-
摘要: 关于井控设备远程控制台三位四通换向阀手柄位置放在中位还是放在工作位的问题，石油工程界存在不同的意见。在介绍液压元件工作原理的基础上，分析了不同手柄位置对液压元件可靠性和寿命的影响，并从目视化管理、操作程序、出错概率等方面对不同手柄位置的优缺点进行了对比分析，认为手柄位置处于工作位，管路压力始终在设备控制范围内，不会出现大幅波动，从而减小了对液压元件可靠性和寿命的影响，而且具有目视化管理更直观、减少了工作程序等优点。综合分析认为，远程控制台待命期间三位四通换向阀的手柄位于工作位比中位好，可以减少井控设备操作隐患，延长井控设备的使用寿命。Abstract: Practitioners in the oil industry are divided over whether the handle of the three-position,four-way steering valve on remote control console of well control equipment should be put in neutral or working position.Based on the working principle of the equipment parts,the effect of different handle positions on the reliability and life span of hydraulic parts was analyzed,and the advantages and disadvantages of different handle positions were compared from the perspective of visual management,operating procedure and error probability.It was concluded that when the handle was in working position,the pipe pressure would be always be in the designed range of the equipment,without significant fluctuation,reducing the negative effect on the reliability and life span of hydraulic parts.Moreover,this position could also make visual management more direct and reduce operation procedures.Therefore it was concluded that the handle position of three-position,four-way steering valve was better in working position than in neutral position,which could reduce operational errors and extend life span of well control equipment.
