摘　　要：稠油斜直井抽油杆柱滞后的问题严重制约正常生产。研究稠油井筒降粘举升工艺 ,找到一种简单经济的解决抽油杆滞后的办法 ,完善稠油开采工艺 ,探索稠油开采的新举升方法 ,意义十分重大。所提出的降粘举升工艺 ,通过在矿场试验 。The problem of sucker rod string lagging in heavy oil slant hole has seriously restricted normal production. It is important to study heavy oil lifting by wellbore viscosity reduction, to find a simple and economical way of solving sucker rod lagging, and to complete heavy oil recovery process. The proposed viscosity reduction and lifting process has obtained good economic benefit in field test.
