LOCALISATION AND LIQUIDATION TECHNOLOGY OF OIL LENS BY MEANS OF FORCED FACILITIES Russian patent published in 2010 - IPC E21B43/263 B09C1/00 

FIELD: oil-and-gas production.

SUBSTANCE: localisation and liquidation localisation of oil lens from subsurface layers of soil includes definition of lens boundaries, drilling of wells, localisation of lens and displacement of oil to the surface. Localisation is implemented by means of passing by contour of oil lens of wells or bore pits, after what it is implemented its loading by explosive of such mass and power, at which after explosion it is implemented creation of oil-water-proof of internal envelope, blocking oil lens by means of sealing and melting of ground. Liquidation includes multiple sequential explosions in the same wells or bore pits occurring shocks of which displaces oil lens from soil. It is possible application of additional ground watering with target of increasing of its density and by this increasing of effectiveness of shock impact which directly moves oil lens upwards.

EFFECT: invention increases effectiveness of oil extraction of oil from soil increasing effectiveness of labour, improves ecology, releases soil from oil pollution.
