Lake Petros High Quality Drilling Tools Hydraulic-Mechanical Drilling Jar

Lake Petro has been committed to providing customers with zero defect products, and discover the now products and technology.

At beginning of the year, Lake Petro got a new order-Hydraulic mechanical drilling jar.
Hydraulic mechanical drilling jar integrate hydraulic principle with mechanical principle, its a new type drilling jar, which can suit for all kinds of drilling operations, and go with drilling tools assembly to decont the well when used. The drilling tool 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 upward or downward jarring force through lifting and landing the drill strings, so it can release resistance and the stick by many times jarring, and recover normal drilling operation prompty. Meanwhile avoid resistance and stick to become further accident, and cause larger economic losses. If releasing force if failed, it can dynamiclly adjust at anytime on sites and be easy to use.
