When the hammer 3 is pushed into the cone socket of the sub 4 with the force specified by the device during the sticking operation. After the conical pair cuts out, the drill string is lifted with a force sufficient to crack the friction clutch. As a result, communication failure occurs. the rod 2 with the housing G and the anvil 8 is struck, which is transmitted to the stuck pipe string, the operation of the SSA continues until the stuck column is released about

The conditioner can be applied not to talc in the drilling process, but also J as known for this.

ISLI YASSY,

The proposed CCA design compared with the prototype improves the reliability of its operation by eliminating the shear of the shear elements, protecting the O i-step and ensuring their guaranteed sequential commissioning. In addition, the proposed CCU simplifies the assembly of the fixing unit of the conical pair.
