防砂卡斜井泵在下二门油田出砂井中的应用

Application of inclined well pump with sand exclusion in sand producer of Xia'ermen oilfieid

介绍了防砂卡斜井泵的结构和工作原理,防砂卡斜井泵采用长柱塞、短泵筒、泵上出口挡砂、泵下尾管沉砂装置,消除了普通泵存在的砂埋柱塞与抽油杆的缺陷。在下二门油田出砂井中的应用效果表明:该种泵能有效地防止砂卡、减少抽油杆断脱,同时减少泵的磨损,延长泵的使用受命。

This paper introduces the structure and operation mechanism of the inclined well pump with sand exclusion, which can makes up the defects of sand-blocked and plunger-jammed and eliminates the problem of sucker rod occurred in ordinary pumps.This is because it has the devices such as long plunger,short pump barrel,reten- tion device and sand-settling device.The application re- sult of sand producer in Xi'ermen oilfield shows that this kind of pump can effectively prevent the pump from wear- ing out and sand-jammed,reduce the dropouts of sucker rod and prolong the service life of it.
