One way hydraulic jar
- One Way Hydraulic Jar
-
1. Introduction
Hydraulic jar (up / down) designed to use with 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 force to generate shock effect and loose card tool stuck.
2. Feature
Tool string is short, small diameter, simple structure, reliable, less wear in downhole, low-cost tools. 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 or 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 tool
