Bidirectional hydraulic jar

1.     Introduction

Hydraulic jar (up / down) designed to use accelerator and flow sub form a coiled

tubing short heavy string. The Jar delay device let the energy stored in the stretched and elongated string accelerator, when the energy released will have a great impact, generating shock effect, loose card tool stuck.

2.     Feature

Tool is anti-torque and can work with motor

Tool length is short, small diameter, less wear in the downhole.Allow a continuous coiled tubing operation.The same tool can change the components and the direction of the outer cylinder

to realize up or down jar. Two tools can be connected in series to achieve simultaneously on up and down

jar.

3.     Application

Suitable for fishing, milling and other high risk string card impedance coiled

tubing operations

This tool can also be used with wire-line tools
