API Downhole Tools Hydraulic Mechanical Drilling Jar and Hydraulic Drilling Jar

JYSZ hydraulic-mechanical drilling jar integrates hydraulic principle with mechanical principle,it's a new type drilling jar, which can suit for all kinds of drilling operations, and go with drillingtools assembly to decont the well when uesd. The drilling tools are often sticked due to many kinds of reasons in down hole when in normal drilling operations, and this type drilling jar is an effective tool for releasing stuck. When the drilling tools are sticked, it can make drilling jar generate upwardor downward jarring force through lifting and landing the drill strings, so it can release resistance and the stick by many time jarring, and recover normal drilling operation promptly. Meanwhile avoid resistance and stick to become further accident, and cause larger economic losses. If releasing forceis failed, it can dynamiclly adjust at anytime on sites and be easy to use.
