METHOD FOR INCREASING WELLS PRODUCTIVENESS Russian patent published in 2005 - IPC

Abstract RU 2250986 C2

FIELD: oil and gas industry.

SUBSTANCE: method includes placement of deep operation body in perforation zone, capable of forming pressure pulses via remote initiation of gas mixture explosions. Depression of bed is performed by lowering liquid level in a well, forming a certain volume of explosive gas mixture in deep body, performing multiple effect on bed without raising of body until well product influx increases. Explosion pressure is set on basis of hydrostatic pressure of well liquid and volume of explosive gas mixture on basis of table provided in description.

EFFECT: higher efficiency.
