Shegli Highland continuous sucker rod service company founded in 2001 is unique corporation specialized in continuous sucker rod production and work service. At present, company annual production capacity has amounted to 1,200,000m with class of Ф20、Ф22、Ф24、Ф25、Ф28、Ф30 and strength grade of D、H、KD.

Continuous sucker rod is made of high quality Cr-Mo alloy metal through a special rolling process whose cross section is circular. Not-jointed continuous sucker rod production is designed according to sucker rod stress, and composed of different segment which is assembled by advanced welding technology.

Not-jointed steel continuous sucker rod has many advantages compared with general jointed sucker rod, included (Not limited to):

1.Large contact area with tubing to lessen tubing-rod eccentric wear;
2.Declining sucker rod up and down resistance, and improving pump efficiency;
3.Weight rate of roof bolt is lighter than general rod;
4.Decreasing dropout frequency and improving roof bolt reliability.

Continuous sucker rod has wider scope than general rod for many advantages, especially in horizontal wells, directional wells and eccentric wear wells.At present, steel continuous sucker rod sucker rod has been widely applied in Shengli Oilfield;

1.Applied in horizontal well, direction well, deviation well, deep well and so on;
2.Applied in eccentric wear well and heavy crude well support by progressive cavity pump;
3.Applied in high volume fluid in deep wells support by ROTAFLEX pumping units;
4.Widely applied in offshore well support by progressive cavity pump;
5.Tried out high volume fluid in deep wells in Xingjiang oilfield with max depth 3,500m (Ф38 pump).

At present, we have more than 10 types of special running and pulling equipments for steel continuous sucker rod which is absolutely necessary. Running and pulling equipments is not only quick speed but also decline noticeably labor intensity. Truck mounted pulling unit can be proceeded fishing broken rod which can be welded joint, assembled and tripped in hole and worked in the working site, which decreases operation time and improves efficiency.
