The ZJS type jar intensifier is a type of downhole fishing jar designed to increase the top jar's jarring force. It runs in conjunction with either YSJ type hydraulic top jar or CSJ type super jar. Its main function is to supply acceleration to the upper end of the jar during the free jarring stroke. The intensifier is essentially a fluid spring that stores strain energy under compression. When the strain is removed, the stored energy is released, accelerating and intensifying the top jarring action. The top jarring action thus creates a direct impact on the fish. In addition, the fluid helps to absorb the shock from the rebounding drill string after the jarring stroke, protecting both the drill tools and fishing tools from damage.
Working Principle
Normally, the jar intensifier is connected on top of drill collar and on the lower end of the drill stem. When the fishing tool engages with the fish, the drill tool is lifted. A large amount of energy was thus stored in the intensifier when the silicone oil in the top chamber of the piston was compressed. As the tool is lifted, when the top jar reaches it's free impact stroke, the stored energy in the jar intensifier is suddenly released, accelerating the drill collars and jars upward. When the top jar reaches its maximum stroke, a strong top jarring action will impact on the fish, resulting in one time jarring force.
The ZJS type jar intensifier is easy to assemble, operate and maintain. No high pressure pre-loading is required.
