High Pressure Hydraulic Jar For Drill Stem Testing Service Big John Jar
The hydraulic jar is a safety tool of drill stem testing string, the hydraulic jar in Halliburton type is called Bigjohn Jar.
The hydraulic jar helps free a stuck tool or tool string by resisting a pull on the workstring, when the workstring is stretched by the pull, tension in the jar is released and an upward impact is delivered to the stuck tool.
The time delay of hydraulic jar required to release the temporary resistance varies in relation to the weight of the pull. For example, a light pull requires more time for release than a hard pull. When tools below the jar are stuck, a steady pull applied to the jar creates an upward impact blow to the string. The jar can be re-cocked when the string is set down.
