CSJ Supper Fishing Jar
CSJ type 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.

Tianhe Downhole motor design d on the most advanced international design technology. We have a Closely cooperating with domestic, surgical research institutes, universities and oilfield drilling companies, and through careful research and development of R & D center in Canada, the design of technical parameters and structure can meet the most demanding oil drilling needs. Tianhe downhole motor is designed for durability and longer service life for different use conditions, with the most stringent specific tolerances for design and manufacturing standards.
The common drill pipe is a rod that connects the drill bit, delivers the drilling fluid and transmits the power in the drilling tool. Our common drill pipe conforms to SY/T5561 and API Spec5DP standards. In order to reduce the wear of the casing and drill pipe, we can weld the wear belt at the end of the drill pipe female buckle joint. Our company has obtained the production and use license of ARNCO 100XT, ARNCO 150XT, ARNCO 300XT and ARNCO 350XT authorized by the American Anke company.
The agitator can improve the effectiveness of bit weight transfer and reduce the friction between drilling tool and borehole through the longitudinal vibration produced by the hydraulic action of drilling fluid, especially in the process of directional drilling to improve the bit weight transfer and reduce torsional vibration. It is a downhole tool used to solve downhole depressurization and improve weight on bit transfer. Smooth weight on bit transfer improves the ability to adjust the bit toolface to reach further target zones. It does not require too much work to adjust the tool face during drilling, keeping the tool face stable and increasing ROP. Particularly suited for horizontal, extended-reach Wells, it can be used in conjunction with MWD, screw, and any bit.
Working Principle
CSJ type super fishing jar effects the top jarring action is by means of hydraulic mechanism which allows taper piston to move in cylinder and stores energy by raising drill tool. When the drill tool attached on the top of super fishing jar is raised, enough time is provided for drill tool to store energy due to the damping action between taper piston and sealing body in pressure body of super fishing jar. When taper piston moves to release bore, the drill tool shall suddenly attract and produce an upward dynamic load along with the instant unloading of high hydraulic oil. The reliable impact working face is designed in the product structure to ensure that large jarring force is provided to stuck fish (drill tool ). A desire return mechanism is designed in order to make a reciprocating jarring action. In order to make a rotation for drill tool in down hole and a circulation for fluid, CSJ type of super fishing jar pass torque by means of spline and meanwhile enlarge the watercourse as far as possible to meet the tests with exception of fluid circulation and other applications.
