The author introduces the qualitative diagnosis on relational surves(tubing pressure between shut-down time)obtained from the screw pump at three conditions:1/Start-up pressure-holding;2/Shut-down pressure-holding (stop the pump at the pressure built-up);3/Stop pressure-holding(stop the pump at normal running meanwhil close-up the production valve).
文章以关井油管压力与关井时间的关系为理论基础 ,利用在开机憋压、关机憋压 (即当抽憋压力达到一定值后停止螺杆泵运转憋压 )、停机憋压 (即在将正常生产的螺杆泵停止运转的同时关闭生产闸门憋压 ) 3种状态下取得的关井油管压力与关井时间的关系曲线 ,对井下发生的各种情况进行定性诊
