摘要
运用PDCA循环方法,对影响试井合格率的原因进行分析,找到了3项主要因素是:卡槽与打捞头滑脱、凸轮未打开、弹簧弹力不足,针对这3项要因提出了相应的改进对策,即改进卡槽坡度、加长凸轮长度、增大弹簧直径,实现了对试井控挂器结构的质量改进,提高了试井测试合格率。
The causes that affect the well testing pass-rate are analyzed by using PDCA cycle method. Three major causes are found, and they are： the salvage head is slipped away from the slot, the cam is unopened, and the elasticity of spring is insufficient. Counter- measures are proposed regarding to these three causes respectively, which are： adjusting the gradient of slot, prolonging the cam and increasing the radius of the spring. Quality improvement for well testing control hanging device＇s structure is made, and the well tast- ing pass-rate is improved.
