DRILLING ACCELERATORS

DRILLING ACCELERATORS

The Hydraulic Jar Accelerator is a hydraulic spring that stores energy when tension is applied to the drilling string. During the jarring stroke, the energy is released upwards to accelerate the drill collars and the upper portion of the jar, intensifying the jarring impact. Accelerators are recommended for use in extended reach or highly deviated wells where jar performance could suffer due to hole drag.

Features

                Sealed and lubricated spline drive provides long service life under high torque and stroking applications.

                Full torque can be transmitted through the accelerator.

                Operation is independent of the fluid circulation.

                 Effective in shallow holes where little pipe stretch is available.

                External sealing surfaces are tungsten carbide-coated to enhance wear and corrosion resistance.

Options

                Standard and high temperature seals available
