YJZ Type Hydraulic Mechanical Drilling Jar Oil Drilling Tools
YJZ type 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. Whatsapp+8615972752793 luben@youlongpetro.com When the downhole tools get struck, it 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. https://www.youlongpetro.com luben@youlongpetro.com 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.Whatsapp+8615972752793 https://www.youlongpetro.com
