API Surface Bumper Jar for Oilfield
DXZ Surface bumper jar is a tool releasing stuck for down hole tools on the wellhead. It applies to release stuck which needs downward jarring like key slot, shrink neck, fall off block, sticking to suck etc. It also can relieve down hole fishing tools when surface bumper jar is working on wellhead. No matter what parts of drill stems stuck, slips down hole tools stuck, fishing tools stuck or testing work over tools, well washing tools stuck, it all can use surface bumper jar to release stuck.
DXZ Surface bumper jar is a new type full mechanical surface bumper jar. It overcomes previous defect of friction type's slips are easy to burn and adjusting is not exact. It can adjust jarring release force at any time, and easy exact stable to adjust.
We produce H2S resistance Jars, which adopt high quality import sulfur-resistance material.
