METC SJ Hydraulic Thruster is an energy conversion device used in oil drilling and workover operations.

It changes the traditional way of WOB by the weight of the lower drill collar.

Without consuming or requiring additional energy and other special equipment, it can give a stable WOB by the function of pressure drop on bit that acting on the upper and lower faces of the SJ tool pistons.

It can solve the technical problem that the weight of the lower drill collar cannot be applied to stabilize the WOB for special drilling operations.

Hydraulic Thruster Advantages

Enhanced stability and directionality by shifting stressed states on drill pipes.

Improved shock absorbing performance.

Better deviation control with hydraulic pressure directly to WOB.

Various BHA combination and wide application scenarios.

Simplify operation with conventional deployment.
