Product details

General

The 70Mpa retrievable packer is a retrievable packer, used for Treatment, Testing and squeeze cementing,with round,hydraulic slips, is a full opening and hook wall packer.

The full opening permits large volumes of fluid to be produced with a minimum pressure drop, and allows the passage of a through tubing type perforating gun.

Structure

Each packer includes a J slot mechanism,mechanical slips, packer element,and hydraulic holddown mechanisim to help prevent the tool from being pumped up the hole if pumping is required during a drill stem test. All of these packers are assembled with drag blocks and automatic J slot sleeves.

Feature

Set the Packer:

Run the packer slightly below setting position then pick up setting depth.

Rotate pipe to the right several turns. Only 1/2 turn is required on bottom to set the packer.

(However it is helpful in deep or crooked holes to turn several turns, using the rotary table is possible, in some cases, the torque in the pipe will have to be worked down to bottom by raising and lowering the pipe several times until the packer sets).

Unset the Packer

Pick up the tubing to open the hdyraulic circulating valve and equalize pressure across the packer.

Bypass Valve

The 70Mpa retrievable packer always run with a bypass valve which for unseting the packer when the operation done,normally ZZTOP recommend two types bypass valve, one is bypass valve with a J slot(Lock open/Lock close),another is a hydraulic circulating valve which is very simple in operating and in high reliable function.
