Product Description

High quality API downhole tools oil packers and cup packer for oilfield

Product Description

Tubing Drain is designed to provide a means of equalizing pressures between the tubing and annulus by simply over pressurizing the tubing string to a pre-set point. When the pre-set point is reached, a set of shear pins will break and the external sleeve will move down to uncover the ports in the inside nipple.

 

There are different types of tubing drains:

1.Rotating- commonly used in conjunction with a rotating anchor and must have a backup to actuate them in the hole.

2.Drop Bar- a bar is dropped down the tubing string from the surface to shear a plug type device

3.Shear Pin- provide the resistance to applied pressure or mechanical manipulations.

4.Pressure Relief- pressure is applied to a predetermined amount to open the device.

Cup packer is mainly composed of upper joint, cup and center tube.

It is a kind of selfsealing packer. The pipe annulus is sealed by interference cup and casing inwall. On the impact of downhole pressure difference, cup expanses to seal the annulus and it just can bear one-way big pressure differential.

Cone cup is the main part of cup packer. It is vulcanized rubber on the metal frame. Cup packer is used in well together with other downhole tools. When the tool down to the designed position, it's sealed by compression between cup and 

inwall and pressure difference. Pull the column to realize unsealing.
