Datasheet


Operation and maintenance

Operation

1. Packer pressure test should be carried out at the pump station before running down the well

2. The packer is lowered to well on the working depth. Lift up well string and turn right. Run down the well string, and when the pressure shows 80-100kn, the setting is completed and the next operation can be carried out.

3. Drifting

4.As long as the downhole string is lifted, the packer can be pulled out.

Precautions

1.Lower the tool slowly to prevent drilling string is not well braked.

2.High pressure sealing grease shall be applied when connecting tool string in well.

3.In case of obstruction, the tool shall be lifted up instead of pressurizing for pass through.


Advantage

RockySea Petro has extensive experience in manufacturing Top packer, and our products have the following advantages.

(1)The external reversing mechanism is adopted to make the Drift max 50 mm

(2) A shoulder protection structure is designed on the sealing mechanism, and the sealing pressure can be increased by 10-15%.

(3) Packing element and rubber are made from hydrogenated butyl rubber, which has high temperature resistance and anti-aging performance.


Principle

A.Setting

When the packer enters the well, the friction block is pasted on the inner wall of the casing and is lowered along with the downhole string. The two cylindrical pins on the reversing coupling connected with the central pipe push the reversing sleeve and drive the connected parts to move down together.When setting is needed, as long as the well string is lifted up and turned right, due to the action of friction block, the two cylindrical pins on the reversing coupling move down along the track on the reversing sleeve, so that the central pipe can move up and down.At this moment, press down the casing string then slip will be opened and clamped on the inner wall of the casing, and the packing element is compressed to seal the annular space of the tubing-casing.

B. Released

When the packer needs to be pulled out after the completion of the operation, as long as the downhole string is lifted up, the two round column pins return to their original position along the reversing sleeve.As the string goes up, the packing elementis recovered. The slip sleeve on the central pipe pushes the cone upward to leave the slip, then the slip is pulled back to realize the unsealing and releasing.


RockySea Petro: A Pioneer in Top Packer Manufacturing in China

A packer is a downhole tool that connects the downhole string. It is used to seal the oil and gas well casing or open wellbore annular space. Also, the top packer can be used for separate layer oil testing, oil production, water plugging, fracturing and others.

Sanajck can provide hydraulic and mechanical top packers to fit different client needs.
