《石油机械》第18卷第10期,1990,第26～30页,图4,表3 在有一定自喷力的抽油机井中,利用惯性抽油原理,使柱塞上行的前半个行程抽油,后半个行程自喷,可以大幅度地提高产量,从而使抽油效率提高。
In a pumping well with flowing pressure to a certain degree, it is recommended, according to the inertia pumping principle, that the oil is pumped during the first half of the plunger upstroke and flows by flowing inertia during the latter half of the upstroke. There will be a big increase in oil production and the pumping efficiency will be improved.
