Introduction

In extended reach and highly deviated Wells, the bidirectional hydraulic jar has more and more obvious advantages over the traditional mechanical jar. Its time-delayed jar and stable hydraulic structure can provide a stable and efficient jar effect in more severe well conditions and application scenarios. The bidirectional hydraulic drilling while jar can apply the maximum impact force within the safe range to the stuck drill pipe to complete the release of stuck. The length and outside diameter of the jar are fully compatible with other drill tools on the drill floor and stand on the drill floor. In drilling mode, the jar is in the middle position and is not affected by any weight on bit or torque.

Features

• With greater overlift capacity, longer free formation and greater impact force.
• Tools with increased strength to cope with high-intensity shocks.
• Effortless jar operation.
• Large bore to allow other downhole tools to pass through.
• Extremely low pressure consumption.
• Optimized tool construction and material to ensure a single tool run time.
• Optimal placement calculated with software for the jar.
