RESEARCH OF MECHANICAL PACKER SITTING STABILITY

The analysis of the accidents of operational belts shows that the main reason for the loss of the belt's efficiency is the additional stresses affecting it, as a result of which the belt is longitudinally and transversely disintegrated, the hermeticity of the groove joints is lost, disintegrated, and crushed. Therefore, this should be checked before the packer is released into the well. A load is applied mechanically or hydraulically to the packer to seat it on the belt. It is known that these forces are applied to the packer, as well as to its components, in dynamic rather than static conditions. However, the approaches to extinguishing its shock nature in certain ways are not enough. For this purpose, it is important to fit the packer fasteners in the belt, remove (release) the packer from the well.
