Carbon Steel Drilling Jar Oilfield Drill Spare Parts
High Efficient Oilfield Fishing Tool Drilling Jar / Super Drilling Jar
Product Overview
Super fishing jar is a fishing tool which the jarring force is larger than other jar with same specifications. It features a closed structure ,reliable performance, easy to adjust and easy to operate. It is a new type of top jarring tool used in oilfield ,geological exploration and drilling operation.
When it is used, the jar intensifier is connected on the top of drill collar and on the lower end of drill stem. When the fishing tool engage the fish and the drill tool is lifted up , the silicone oil in the top chamber of piston is compressed and a large number of energy is thus stored .During lifting , when top jar reach up to free impact stroke, the stored energy in the jar intensifier will suddenly release, the energy suddenly released will provide a very large acceleration for drill collar and top jar to move upward .When the top jar reaches up to max. stroke, a strong top jarring action will impact directly on the fish, as a result, one time jarring is produced, and more times jarring will be effected by repeating this course.
Main Advantages of Our Oilfield Fishing Jar:
(1) . Designed and manufactured according to API Spec 7-1.
(2) . Tool is anti-torque and can work with motor.
(3) . Tool length is short, small diameter, less wear in the downhole.
(4) . The same tool can change the components and the direction of the outer cylinder to realize up or down jar.
