METHOD OF DEVELOPMENT OF HYDROCARBON DEPOSITS Russian patent published in 2003 - IPC

FIELD: development of hydrocarbons deposits, particularly, of gas-hydrate deposits and also of deposits of solid and high-viscosity hydrocarbons. SUBSTANCE: method includes drilling of pool consisting of, at least, two formations isolated from each other and from adjacent rocks by impermeable connectors. Drilling of pool is accomplished by, at least, two wells with, at least, one horizontal section. One of said two wells is injection and the other, producing one. Heat carrier is injected through injection well. Withdrawal of hydrocarbons from, at least, one producing formation is carried out through producing well. Heat carrier is used in form of liquid radioactive wastes. Injection well is drilled with number of horizontal sections corresponding to number of drilled formations. Upper horizontal sections are arranged in producing formations, and perforated lower horizontal section consisting of, at least, two radial sections, in nonproducing formation. Said radial sections are used for injection of liquid radioactive wastes. Producing well is drilled with number of horizontal sections less or equal to number of horizontal sections of injection well. They are selected to provide for maximum distance between each other. Upon completion of injection of liquid radioactive wastes, isolating bridge is installed in zone of impermeable connector, on section of transition of injection well from producing formation to nonproducing formation. Then, sealed isolation of injection well lower section from its overlying section is accomplished. EFFECT: simplified technology and intensified heat transmission. 8 cl, 8 dwg, 1 ex
