Use during drilling operation
API 7-1 ZSXJ Type Hydro-mechanical Drilling Jar
The hydro mechanical drilling jar type ZSXJ can be used either independently or in conjunction. It is designed for use during drilling operations to apply an intensified force either up or down against a stuck portion of the drilling string .Its unique design combines both a hydraulic time delay release and a mechanical latch mechanism, in one relatively short, double acting drilling jar. Therefore, it is an ideal tool for drilling directional well, complicated well and slant well.
