초록 ▼

A process and system for insitu hydrogenation employing a gas generator in a borehole for burning a hydrogen-rich mixture of hydrogen and oxygen. The gas generator comprises a housing forming a chamber with a combustion zone at one end and a restricted outlet at the other end. A cooling annulus surrounds the chamber with passages leading from the annulus to the chamber. Hydrogen and oxygen are supplied downhole to the generator to form a hydrogen-rich combustible mixture in the combustion zone which is burned whereby hydrogen and steam are injected from the restricted outlet. Hydrogen also is supplied to the cooling annulus. The flow of hydrogen and oxygen to the generator is controlled to maintain the temperature of the exhaust gases at a level sufficient to crack the hydrocarbons in the formations into lighter segments for reaction with the excess hot hydrogen to form lighter and less viscous end products which are recovered from a production well.

A process of hydrogenating hydrocarbons in underground formations penetrated by a borehole and wherein a gas generator is located in the borehole at or near the level of said formations, said gas generator comprising: a housing forming a chamber and having an upper inlet end for receiving fuel and an oxidizing fluid, said chamber defining a combustion zone, an igniter for igniting combustible gases in said combustion zone, a restricted lower outlet for the passage of heated gases, and an annulus surrounding said chamber and having passages leading to said chamber, said process comprising the steps of: flowing through said borehole from the surface to said gas generator, by way of separate passages, hydrogen and oxygen to form a hydrogen-rich combustible mixture in said combustion zone, igniting and burning the combustible mixture in said combustion zone, and controlling the flow of hydrogen and oxygen to said gas generator to maintain the temperature of the gases and fluids flowing through said outlet at a level sufficient to cause hydrogenation of the hydrocarbons in said formations. A system for use for hydrogenating hydrocarbons in underground formations penetrated by a borehole, comprising: a gas generator located in the borehole at or near the level of said formations, said gas generator comprising: a housing forming a chamber and having an upper inlet end for receiving fuel and an oxidizing fluid, said chamber defining a combustion zone, an igniter for igniting combustible gases in said combustion zone, a restricted lower outlet for passage of heated gases, and a cooling fluid annulus surrounding said chamber and having passages leading to said chamber, a source of hydrogen located at the surface, hydrogen conduit means coupled to said source of hydrogen and extending from the surface to said gas generator for supplying hydrogen from the surface to said inlet end of said gas generator located in said borehole, a source of oxygen located at the surface, oxygen conduit means coupled to said source of oxygen and extending from the surface to said gas generator for supplying oxygen from the surface to said inlet end of said gas generator located in said borehole, means coupled to said gas generator for diverting a portion of said hydrogen from said hydrogen conduit means into said annulus for cooling said gas generator and gases of combustion and for providing hot hydrogen, and means for controlling the flow of hydrogen and oxygen to said gas generator to form a hydrogen-rich combustible mixture in said combustion zone and to maintain the temperature of the gases and fluids flowing through said outlet at a level sufficient to cause hydrogenation of the hydrocarbons in said formations.
