METHOD FOR SPEEDING UP EXTRACTION OF HYDROCARBONS AND DEVICE FOR ITS REALIZATION Russian patent published in 2005 - IPC

FIELD: oil industry.

SUBSTANCE: method includes pulse treatment of productive bed by energy of atmospheric electricity by using lightning discharge. Prior to initialization of storm discharge voltage of electric field above well is measured using measuring block. Initiation of storm discharge is performed when reaching value of strength of electric field above well no less than 30 kV/m and enough for forming leading channel of lightning. To exclude corona as receiver of electric energy metallic mast is used, on upper end of which metallic fragment of spherical form is positioned having smooth external surface, or smooth metallic wire is used with its possible raising towards storm cloud. Output of receiver is connected to casing column of well. Powerful electric discharge along casing column and through its perforated portion gets into area of productive bed and disperses there.

EFFECT: simplified method, simplified construction of device, higher product yield.
