API 7-1 JYQ Type Double-acting Mechanical-hydraulic Drilling Jar
The double acting mechanical-hydraulic drilling jar type JYQ is designed for drilling operation to apply an intensified force either up or down against a stuck portion of the drilling string. It incorporates the feature of both hydraulic and mechanical drilling jars, without of the inherent disadvantage of either type. Its unique design combines both a hydraulic time delay release and mechanical latch mechanism in one relatively short, double acting drilling jar.
