Screw Pump Torque anchor

 

1 Application

Torque anchor is a kind of anchor tool which specially designed for screw pump,simple

structure,easy to use.

 

2 Structure

 

It is mainly consists of upper sub,anchor, centralizer,reed and mandrel etc.When the screw

pump rotates,torque anchor can effectively avoid the tubing rotate.It has the characteristics

of simple structure,simple installation,working flexible,safe anchoring,widely used in anchoring

of screw pump and anchor of tubing of tubular pump.

 

3 Working principle

 

When the screw pump rotates,the rotor rotates thus drive the stator,upper sub and mandrel

to rotate,anchor opens,anchors on the casing,anchoring completed.When the screw pump

stops,stator releases energy under spring action,anchor closes under the contractility of reed,

releasing completed.

5 How to use

1.Using suitable anchor according to size of casing,connect at the bottom of pump stator.

2.Running direction:BOX thread UP,PIN thread DOWN,fasten tight.

3.Running pump stator at designed depth,rotate clockwise with torque of 400N·M,then fix the

tubing string with wellhead,anchoring completed.

 

6 Notes

1.Keep dry and handle with care during transportation.

2.Wiper trip and clean well before running.
