HOLLOW SUCKER ROD
- Transmission of reciprocal motion from surface drive to sucker rod pump plunger;
- Extraction of produced fluid from pump to wellhead through inner channel;
- Hollow sucker rod and tubing string washing in order to remove paraffin and salt deposits and to improve equipment operation efficiency;
Hollow sucker rod is used as component of dual completion, heating and washing equipment.
Application
- Transmission of reciprocal motion from surface drive to sucker rod pump plunger;
- Extraction of produced fluid from pump to wellhead through inner channel;
- Hollow sucker rod and tubing string washing in order to remove paraffin and salt deposits and to improve equipment operation efficiency;
- Injection of chemical agents or steam into tubing string or bottom-hole formation zone to reduce effects of complicating factors and to improve oil production;
Advantages
- Hollow sucker rods are made of strengthened heat-treated cold-rolled pipes;
- Hot-upset head ensures equally efficient cross-section of sucker rod and equal inner diameter of channel along entire length;
- Rolled connection threads ensure high fatigue strength;
- Thrust cones reduces flexural stress at threads and ensures tight connection;
- Moulded guides are available;
Benefits
- Separate lifting of produced fluid in dual completion & injection equipment sets;
- Subsurface equipment smaller dimensions due to concentric arrangement of lifts;
- Decrease metal consumption by using hollow sucker rods without tubing string;
- Higher fluid velocity reduces deposits of paraffin and salt;
