作者研究了泵径及泵挂深度对油井免修期和阀工作周期的影响。分析表明,柱塞免修期大大高于阀的工作周期。由于强化开采也发现深井泵工作周期逐年降低。 为了增加海上抽油井的免修期和迅速更换磨损的深井泵,(辶占)议在泵油时使用串连式深井泵,即在油井中储存一个备用的深井泵。 The authors studied the effect of pump diameter and pump-in depth on oil well repair-free and valve duty cycles. Analysis shows that the plunger is significantly longer than the valve repair duty cycle. As the enhanced mining also found that deep well pump work cycle decreased year by year. In order to increase the cost of oil-free wells at sea and to replace worn-out deep-well pumps, a tandem deep-well pump was used to pump the oil, ie a spare deep-well pump was stored in the well.
