Granted: 1995-08-09
Abstract: FIELD: pulse treatment of formations applicable in gas and oil producing industry. SUBSTANCE: device for treatment of producing formations, in its simplest version, has two pulse jet generators interconnected by transportation channel 7. Working medium from dispensing channel 8 is supplied to inlet of the dirst generator through nozzle 5 and, simultaneously, to transportation channel 7 and nozzle 6 of the second generator. Length of transportation channel is selected to ensure displacement in time of supply of pulse jets from this generator relative to supply of pulse jets from the first generator. As a result, alternating supply of combination of pulse jets of working medium in formation takes place. In one of versions, axes of outlets of each generator are in planes running through longitudinal axis of device and cross each other at angle of 360 deg./m, where m is total number of generators. EFFECT: increased efficiency of action of working medium (liquid, gas, steam-gas, etc) on producing formation due to producing the nonuniform wave field and extension of region of its effect on formation. 2 cl, 5 dwg
