ORCHID ENERGY-Hydraulic Mechanical Drilling Jar

HYDRAULIC MECHANICAL DRILLING JAR

TECHNICAL SUMMARY

Hydraulic mechanical drilling jar is integrate hydraulic principle with mechanical principle and applies to all kinds of drilling operations and be used through combining with drilling tools. This jar is equipped with a mechanical safety latch and mechanical latch for jarring downwards.
When the downhole tools get struck, the hydraulic mechanical drilling jar can generate upward jarring or downward jarring through lifting and landing drilling strings, and release block and stuck by several times jarring to recover normal drilling operation promptly. Avoiding resistance and stuck which may cause further accident and caused greater economic loss. If releasing force is failed, it can dynamically adjust at any time on sites.
