Hydromechanical perforator

|
Perforators PTM 60... 168: usual - of К type; to operate in the gas spheres - of G type; to operate up to 6000 m depth - of VD type, are purposed to make openings in casing and tubing strings of home and import production that are located in a borehole for their cavity communicating with out of pipe' area. They let to restore fluid circulation during the repair process and borehole' mastering, to prevent the lifting of tubes with fluid, to make topping-ups into the cement circle out of the casing string, to increase productivity, the production culture, the safety during the repairing process, to reduce the environment pollution.
Method of running-in into a borehole - on a wire, on a rope, on a casing string, by free dropping.
Generator for breaking through with tubes is potential energy of the fluid lifted in the pipes, pressure of the pumping unit.
