WELL BOTTOM ZONE TREATMENT METHOD, OIL CRACKING METHOD AND DEVICE FOR ABOVE METHODS REALIZATION Russian patent published in 2006 - IPC E21B43/25 E21B28/00 C10G15/00 

FIELD: oil production, transportation and refining, particularly methods for physical-chemical high-viscous hydrocarbon cracking, for oil production and injection well bore and well bottom zone treatment, for treating wells after repair and water-intake wells, in underground leaching, for in-situ light-weight hydrocarbon production in separate well to obtain light-weight hydrocarbons having predetermined physical and chemical properties.

SUBSTANCE: method involves diagnosing well bottom zone of formation; applying acoustic action to well bottom zone with the use of vibration oscillating members; correcting treatment parameters subsequent to feedback results. The acoustic action is applied with the use of acoustic fields simultaneously acting in vertical and horizontal directions. The well bottom zone is simultaneously treated with axially helical acoustic field which is discrete in space. The axially helical acoustic field is created by vibration oscillating member switching to provide creation of p-dimensional field net structure. Ultrasonic hydrocarbon composition cracking method and device for above methods realization are also disclosed.

EFFECT: possibility to change oil physical and chemical properties, increased oil well output and reduced oil production and transportation costs, improved efficiency of well treatment and cracking process due to reduced production cycle time and power inputs for technological process performing, possibility to eliminate equipment used for oil conditioning and refinery.
