1. Description
QY-A hydraulic drilling jar is a new kind of drilling jar which is suitable for a wide range of drilling operations. This drilling jar overcomes the defects of pure mechanical drilling jar or pure hydraulic drilling jar and combines with merits of them. Mechanical lock and hydraulic delay works together in the process of jarring up and jarring down.
The QY-A drilling jar has following features:
1) It can avoid unexpected strike effectively.
彩铅手绘2) No need any safety clamps or other special actions on the drilling or tripping.
3) Free position in the BHA (in tension, neutral or compression).
4) Mechanical lock unit is not affected by the torque.
5) The relea force of jarring up or down can be adjusted on the drilling platform. Its operation is
very simple, exact and stable.
6) Hydraulic delay allows the driller to adjust the jarring up or down force.
7) Enclod oil chambers increa als and components life.
8) Suitable to work in high temperature situation.
9) It is an ideal tool for controlled directional well and horizontal well.

QY-A is a new kind of drilling jar which combines the mechanical with hydraulic structures. The hook lifts the drill strings to make the mandrel move up, the spring unit takes place elastic deformation at the pull or push. The more energy from the hook, the spring unit does the greater deformation. When the deformation reaches high-point, the trip sleeve opens immediately and engages with friction sleeve, and then the jar enters the hydraulic-delay state. The cable hoist is baked at the same time. The drilling jar is
