DEVELOPMENT METHOD OF DEPOSITS OF HIGH-VISCOSITY OILS OR BITUMENS Russian patent published in 2011 - IPC E21B43/24 E21B43/25 

FIELD: oil and gas industry.

SUBSTANCE: deposit development method involves construction of well with underground storage tank, drilling of formation with horizontal wells the heads of which are bound through remote controlled gate valves and header with underground storage tank, warming of formation, extraction of product in underground storage tank and its pumping-out to surface with pumps. Warming of formation for bringing its product to fluid state is performed with combined action of electromagnetic and acoustic fields created with emitters placed into horizontal wells with possibility of periodic displacement. Emitters are connected via wellhead seals and the appropriate delivery lines inside the well with ground generators of high-frequency and acoustic vibrations. Warming of formation sections is started from head of horizontal wells to working face for warming in the next formation sections not covered with heat of flowing product.

EFFECT: improving development efficiency of deposits of high-viscosity oils and bitumens.
