YJS Hydraulic Jar Intensifie
YJS hydraulic jar intensifier is a kind of down hole fishing jar tool designed to increase jarring function for up jar. So it must be used together with super fishing jar. It could accelerate for the top end of jar and the drill collar connecting with its bottom end when working, so to get larger jarring force on stuck point, and reduce quake of drill stem springback after jarring at the same time.
We produce H2S resistance Jars, which adopt high quality import sulfur-resistance material.
