US 2023/0066142 A1 · DOWNHOLE TOOL FOR JARRING

Abstract

Examples described herein include systems and methods associated with a mechanical service tool. In one example, the service tool includes a power jar, an accelerator, and a linear actuator. The accelerator can be coupled to the power jar and provide assistance to the power jar. The linear actuator can be coupled to the accelerator and configured such to pull the accelerator spring within the accelerator with a force sufficient to fire the power jar. When the power jar is in a released state, the linear actuator can also be used to pull or pull the entire accelerator and power jar assembly, which in turn can push or pull the target object within the wellbore. The linear actuator can also be used to move the power jar from a released state to a set state.

Dependent claims

A mechanical service tool comprising:

a power jar, the power jar comprising a jar spring and a hammer, wherein the jar spring is configured to impart a force on the hammer, and wherein the hammer releases based on a threshold level of force and produces an impulse upon impact with an anvil;
an accelerator coupled to the power jar and comprising an accelerator spring that transfers force to the power jar, wherein release of the hammer causes the accelerator spring to release and impart an additional force to the hammer;
and
a linear actuator coupled to the accelerator and configured such that actuation of the linear actuator imparts force to the accelerator.
