摘　　要：针对文明寨油田出砂造成的生产难题,试验应用了无泵采油工艺———将油管作为泵筒、若干个举液器作为柱塞,通过杆式举液器在油管内往复运动实现分段举升液柱的一种工艺方法。它能有效地将油管内砂粒形成分段沉积,大幅度减少抽油杆砂卡几率。WM100井试验应用表明,作业免修期延长346 d,具有明显的防砂卡效果。It was very difficult to produce oil in sandy well,no-pump production techniques were tested in Wenmingzhai oilfield,the pump of no-pump production was the tubing,the plunger of no-pump production was some Raise Liquid Device,through such repetitive cycles,the raise liquid device lifted subsection liquid.The subsection sand would be deposited by the raise liquid device;the probability of sand block sucker rod would be decreased substantially.Since 2008,the test of no-pump production techniques showed that the production time of the WM100 sandy well was extended by 346 days,and the effect of sand prevention was obvious.
