Description
- Hydraulic-Mechanical Drilling Jar is a jarring and stuck releasing tool. It integrates the up jar and down jar impact and can release the stuck accident occurring during drilling. Upon the request, the tool can automatically control the impact strength and times of jarring. It is an ideal tool for vertical well and deflecting well.
- Hydraulic jar (up / down) designed to use accelerator and flow sub form a coiled tubing short heavy string. The Jar delay device let the energy stored in the stretched and elongated string accelerator, when the energy released will have a great impact, generating shock effect, loose card tool stuck.
- The one-way shock absorber (bumper )is a kind of drilling tool. It can effect shock absorbing and shock reduction by means of elastic deforming and anti-coagulation produced from hydraulic oil under the outside force.
- Its advantages such as simple structure, reliable working performance and easy to maintain can well absorb shocking and vibrating load from drill strings during drilling operation. Therefore, using of shock absorber can raise in structure the service life of drill bit and drill pipe, speed up drilling, get rid of drilling jumping, well protect surface equipments and drilling tools.
RIGRS Drilling Jar Features:
- Designed and manufactured according to API spec 7-1.
- Tool is anti-torque and can work with motor.
- Tool length is short, small diameter, less wear in the downhole.
- The same tool can change the components and the direction of the outer cylinder to realize up or down jar.
