TECHNIQUE INTENSIFYING OIL OUTPUT Russian patent published in 2003 - IPC

FIELD: oil and gas production. SUBSTANCE: invention is intended to raise oil and gas yield of productive pools of oil and gas wells by their exposure to energy of shock wave excited by electric discharge in fluid of bottom zone. Technical result of invention lies in intensified production of oil with less energy consumption thanks to effective action of electrohydraulic pulse shock wave on productive pool of well, in diminished overall dimensions of pulse source of energy and in reduced production cost. With this in mind electrohydraulic shock wave is generated in fluid in bottom zone of well by pulse discharges with the aid of capacitor discharge unit with spark gap sunk into well through casing string. Shock wave is excited from outside of casing string and for this capacitor discharge unit is brought out of limits of casing string through hole made in it. Shock wave generated in fluid is directed into oil-bearing soil to separate oil from soil. EFFECT: intensified oil output. 1 cl, 3 dwg
