摘要： Extracting energy from a naturally-occurring underground hot rock formation includes enabling fluid to flow, at least partially under the influence of gravity, through a fluid injection well to the hot rock formation, converting the kinetic energy of the flowing fluid into electricity, using at least a portion of the generated electricity to preheat the fluid before it reaches the hot rock formation, heating the fluid with the hot rock formation and, subsequently, extracting energy from the heated fluid for use in connection with an application.

摘要： A geothermal energy system in which a bore hole is drilled into the earth to a depth where a predetermined temperature gradient exists between the earth's surface and the bottom of said bore hole. A liquid refrigerant line passes down the bore hole and connects to an evaporator where the geothermal energy is used to vaporize the refrigerant and from there it passes back up through a high pressure gaseous refrigerant return line to a gas operated turbine located at the earth's surface. The spent refrigerant exiting from the turbine is cooled in a condensing unit and recirculated to the subterranean evaporator unit. The turbine may be used to drive a suitable electrical generator for power production purposes.

摘要： In the recovery of energy from geothermal brines and other water containing or hot water sources, such brine or hot water under pressure is introduced into direct heat exchange contact with a working fluid such as isobutane, the resulting hot isobutane is expanded in a turbine to produce work, the turbine discharge is condensed and returned to the heat exchanger and the cooled brine is withdrawn from the column. The present invention is directed to recovery of working fluid dissolved and/or entrained in the spent geothermal brine or water withdrawn from the direct contact heat exchanger, including the steps of settling the brine in a settling tank to recover some of the isobutane, flashing the remaining brine to flash off additional isobutane and steam stripping the spent brine to drive off further isobutane, the recovered isobutane in each of the steps being recycled to the direct contact heat exchanger.

摘要： There is disclosed a method for recovering energy from subterranean geothermal brines and increasing geothermal well production. The method comprises establishing a column of brine in a well casing having a tubing therein, open at its lower end to the column of brine and injecting a high pressure vapor such as nitrogen or steam into the bottom of the tubing in sufficient quantities to form a mixture of brine and vapor having a substantially lesser density than the surrounding column of brine whereby the hydrostatic head of the column of brine lifts the mixture to the surface. The mixture is withdrawn from the well and passed to a vapor-liquid separator where the vapor portion is separated without effecting any significant reduction in pressure of the produced mixture, whereby the pressure is maintained on the brine in the well at a sufficient value to prevent carbonate and scale formation. In the preferred embodiment, the separated vapor is divided into two portions, one portion goes to production and is used to produce energy or as a high temperature heat source. The other portion is repressured and injected into the well as the source of high pressure vapor used therein. The brine separated from the vapor is depressured and the evolved vapor is expanded to produce useful work in a plurality of states. In a preferred embodiment using steam, the vapor is separated by contact of the vapor with brine from a succeeding brine depressurization step, condensing that portion of the vapor intended for subsequent power generation.

摘要： The flow from geothermal wells is stimulated by injecting a liquid at selected levels in the well with the liquid having a boiling point below the temperature of the geothermal fluid at the levels of injection at the operating pressure at the levels of injection. The geothermal fluid and vaporized injected fluid from the well are applied to a system for extracting the heat energy as well as for cleaning sand and other well depositions that may accumulate in the geothermal well. The system may include a direct contact heat exchanger having either a vertical chamber or a horizontal chamber. The contactor has a plurality of zones including a boiler zone, one or more separation zones, and at least one heat exchange zone. The contactor may also include a wash zone and a flash zone.In the wash zone there is advantageously included recirculation trays vertically spaced for washing the vapor to remove entrained substances, such as minerals dissolved in the fluid from the geothermal wells. The recirculation trays include a manway for ease of access and service. The vaporized fluids from the contactor are passed through a power extracting gas expansion device, with the composition of the vapor being controlled to maximize the power extractable by the gas expansion device.

摘要： Heat energy from hot geothermal fluids supplied by different temperature wells is transferred by heat exchange into a power fluid cycle, preferably of the dual fluid type, at different points in the cycle, which both enables an increase in peak cycle temperature to be achieved and allows more heat energy to be transferred into lower temperature points in the cycle. The result is an increase in the amount of power which can be developed per unit of geothermal fluid supplied.

摘要： A geothermal system is used for obtaining heated heat transfer fluid, such as steam, via heat transfer with an underground reservoir of magma. The geothermal system includes a wellbore extending between a surface and into an underground chamber formed in a reservoir of magma. The chamber may be formed by injecting a fluid at an increased pressure into underground magma to form a cavity that acts as the underground chamber.
