With the development of the oilfield, deviated wells, sidetracking wells and horizontal wells have more and more important function,whereas the particularity of casing programme limited the landing depth of sucker rod pump,and affected the producibility of oil well seriously.
随着油田的开发,斜井、侧钻井、水平井等非直井在油田开发中起到越来越重要的作用,但由于井身结构的特殊性,限制了有杆泵的下入深度,严重影响了油井的生产能力,同时抽油井杆管偏磨,已成为非直井降低产量,增加作业成本、增加杆管成本的主要矛盾。
