الوصف

our fishing jar mainly include super fishing jar, jar intensifier, surface bumper jar and bumper sub. The super fishing jar adopts for hydraulic principle upward jarring, the jar intensifier is used for increasing jarring force to the super fishing jar, so it must be used together with the super fishing jar. The surface bumper jar is used in superficial drilling work and provides downward jarring for stuck drill stem, it often used on wellhead. The bumper sub generates downward jarring force by drill pipe itself gravity.
