Tool Introduction:

Telescopic tubing is used in the completion string to adjust the change of tubing length caused by temperature or pressure changes. It can maintain the pressure inside the oil pipe and ensure its safe expansion and contraction. The telescopic tube can transmit torque and can be placed on the upper part of the packer or in the middle of the two-stage packer depending on the specific situation.

Structural features:

① Strong pressure bearing capacity, reliable sealing, and large expansion and contraction stroke;

② Adjustable opening pin combination, shear force can be adjusted within the required range;

③ Can transmit torque at any position.

Operation:

Connect the expansion pipe to the appropriate depth of the pipe column, and after the packer seat is sealed, the expansion pipe is in the open position. It is a compensation mechanism for the length of the pipe column caused by internal and external pressure or temperature changes.
