METHOD OF EFFECT ONTO OIL RESERVOIR WITH ACOUSTIC FIELD BY MEANS OF DEEP WELL ROD PUMP OPERATION IN WELL Russian patent published in 2009 - IPC E21B43/16 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas industry, particularly to implementation of acoustic effect onto oil reservoir. The method consists in flowing operations. A row of grooves for facilitating small turbulent vortexes is made on the surface of a rod perpendicular to its axis at a calculated space. A set of rods with grooves is arranged at a calculated space around the circumference of the face of the hollow cylinder. The hollow cylinder with the set of rods with grooves is assembled on the face of the deep well rod pump perpendicular to a flow of oil-water-gas mixture. The deep well rod pump with hollow cylinder with set of grooves is lowered into well on oil-well tubing. Oil-water-gas mixture is sucked by means of the deep well rod pump from perforated holes of the well creating small turbulent vortexes. Ultrasound is created with small turbulent vortexes. Ultra sound is transmitted into oil reservoir through perforated holes.

EFFECT: increased efficiency of production wells equipped with oil-well tubing, deep-well rod pumps and perforated holes.
