Relation Between Rational Immersible Degree and Pump Efficiency in Pumping Wells

Determination of rational immersible degree can fully improve the efficiency of oil recovery system on condition of keeping oil wells in normal production. Relation formula and curves between immersible degree and pump efficiency of oil wells were achieved through regression on the field data and according to different water-cut levels in the first block of Shengtuo oilfield. Immersible degrees in oil wells with low pump efficiency were adjusted by using the relation curves.
