IMPLOSIVE MULTIPLE ACTION HYDRO-GENERATOR OF PRESSURE Russian patent published in 2007 - IPC E21B43/25 E21B37/00 

FIELD: engineering of equipment for completion and maintenance of oil and gas condensate wells, possible use for increasing operation resource of plunger pairs of implosive multiple action hydro-generators of pressure during operation in inclined and horizontal oil extracting wells under conditions of polluted working environment.

SUBSTANCE: in accordance to the invention, device contains intake pipeline with apertures for feeding formation pressure of well liquid, implosive chamber cylinder, connected by a sub to the intake pipeline, plunger, connected to pumping bar, working chamber, consisting of working cylinder with windows and pressure concentrators, locking valve, rod, cylindrical compression spring and a case with rigid spring-loaded stop, locking valve sleeve, connecting the cylinder of implosive chamber to the working chamber. In accordance to the invention, plunger is connected to pumping bar by means of a sleeve, consisting of the body and upper and lower half-sleeves. Upper half-sleeve is rigidly connected to upper bar and the body. Lower half-sleeve is rigidly connected to the plunger, and also connected to the body with possible angular displacement, and is made with radial gaps relatively to the body. Contact surfaces of the lower half-sleeve and the body are made in form of spherical end thrust bearing. Amortization insert is installed between ends of the upper and the lower half-sleeves.

EFFECT: increased working resource of implosive multiple action hydro-generator of pressure.
