Fishing Jar Down Hole Fishing Tool Drilling Jar for Oilfield
Product Introduction
Super fishing jar is an advanced fishing and jarring tool, which applies hydraulic and mechanical principle, adopts for advanced technology and concentrates advantages of all kinds of fishing and jarring tools. It has compact structure, reliable property, convenient to adjust, easy use. It is a new type upward jarring tool used in petroleum and geological explorations.
Superior Hydraulic Fishing Jar is a straight pull, up only, jarring tool that utilizes a special valve section to meter oil from one side of the piston to the other side. This allows for controlled jarringactionduringastuckfishrecov- ery.
Design Features of Our Fishing Jar:
- Tool string is short, small diameter, simple structure, reliable, less wear in downhole, low-cost tools.
- Continuous coiled tubing operation.
- The same tool can change the components and the direction of the outer cylinder to realize up or down jar.
- Two tools can be connected in series to achieve simultaneously on up or down jar.
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.
