摘要
针对河南油田稠油出砂冷采工艺中原油含砂量大、空心抽油杆易被砂埋等特点 ,设计了空心抽油杆分段冲砂器 ,解决了空心抽油杆管柱只能洗井不能冲砂的问题 。
With high sand content in crude oil and hollow sucker rod is often buried by sand,which is common in sandy dense oil cold recovery progresss in Henan Oilfield.So the stepwise sand washer was designed for the hollow sucker rod to solve the problem that the hollow sucker rod only had the well flushing function without sand washing function and the effect of the application is perfect.
