YJS Hydraulic Jar Intensifie
YJS hydraulic accelerator is a downhole tool designed to increase shock force of hydraulic upper hammer.It needs to be used in combination with the hydraulic upper punch.It speeds up the connection between the top and bottom of the jar and the drill collar to achieve greater shock force at the snap point.At the same time, it can reduce the vibration of the drill string rebound after shock.
We produce H2S resistance Jars, which adopt high quality import sulfur-resistance material.
