Overview of Super Fishing Jar
The CSJ Type SUPER FISHING JAR is a premium fishing tool engineered to recover stuck BHAs (Bottom Hole Assemblies) in oilfield, geological, and drilling operations. As a top-tier drilling jar, it utilizes a hydraulic mechanism where a taper piston moves within a sealed cylinder, storing energy as the *drill tool* is raised. Damping action between the piston and sealing body allows optimal energy accumulation. Upon piston release, high-pressure hydraulic oil instantly unloads – generating a powerful upward impact (up to 1,000,000 lbf) directly transferred to stuck "fish" (e.g., drill tools). Its robust construction features impact-resistant working faces and supports fluid circulation/tool rotation via spline torque transmission.
Advantages of Super Fishing Jar
