Fishing Jar, also known as fishing jar, is an efficient fishing and unblocking tool designed for oilfield drilling operations. It combines advanced fishing technology with jarring and unblocking functions, and is specifically used to deal with the problem of fish falling in drilling tools and tools during drilling. By generating a strong impact force, it helps to loosen and salvage the stuck fish in the well, effectively ensuring the smooth progress of oilfield drilling operations. It is an important equipment for improving oilfield mining efficiency and reducing operating costs.
________________________________________
The Fishing Jar produced and sold by our company Huichi Petro is mainly composed of upper joints, lower joints, pistons, cylinders, and energy storage springs. When the equipment is connected to the drill string and lowered to the fish falling position, the piston moves up and down in the cylinder by lifting or lowering the drill string, compressing the energy storage spring to store energy. When a certain level of energy storage is reached, the energy is released instantly, generating a strong upward or downward shock force, acting on the fish, loosening the drill tool or tool at the stuck point, making it easier to salvage.
________________________________________
o The hydraulic energy storage mechanism is adopted to store energy through the damping effect of the tapered piston and the sealing body, and the upward dynamic load is released instantly. The shock force is far superior to the tools of the same specification, which can effectively cope with deep wells and high-load scenarios.
o Reliable design of impact working surface and reciprocating return mechanism, support multiple continuous shocks, and improve the efficiency of unblocking.
o Closed structure: high reliability, adapt to high temperature, high pressure and complex downhole environment, and reduce the failure rate.
o Torque transmission and circulation channel: The built-in spline structure transmits torque, expands the fluid channel, and ensures the rotation of downhole tools and mud circulation requirements.
o Easy to operate: compact structure, intuitive and easy-to-understand operation interface, reduce the difficulty of operation, and improve the efficiency of salvage operations.
o Flexible adjustment: With multi-level shock force adjustment function, the shock force and frequency can be adjusted through simple operation according to the actual situation of the fish being stuck, such as the depth of the stuck point, the type of fish, etc., to accurately adapt to different salvage operation scenarios and achieve efficient salvage.
o Equipped with multiple safety protection devices, such as overload protection, anti-loosening device, etc., to ensure that the equipment itself is stable under high-load working conditions and will not be damaged due to excessive shock force or improper operation, thus ensuring the safety of operators and equipment.
