摘要： A system and method for geothermal heat production. A balanced geothermal energy transfer loop includes a first wellbore and a second wellbore extending from surface to a subterranean geothermal formation and a plurality of balanced open hole circuits extending between the first wellbore and the second wellbore through the geothermal formation, forming a substantially sealed closed loop. Each of the plurality of circuits is designed or modified to have a substantially equal circuit parameter. The circuit parameter may include one or more of circuit fluid velocity, circuit pressure drop, circuit volume and/or circuit length. The circuit parameter may include circuit length and volume, and the circuits connect the supply/return wells in a first out/last in configuration.

摘要： Systems and methods for drilling a geothermal well can include drilling a first borehole to a geothermal target, the first borehole defining a longitudinal axis; and drilling a first portion of a second borehole having a first end and a second. The first end of the second borehole extends from the first borehole, the first portion extends downwardly and outwardly from the longitudinal axis of the first borehole, and the first portion of the second borehole is in fluid communication with the first borehole. The techniques can include drilling a second d portion of the second borehole. The second portion extends downwardly and towards the longitudinal axis of the first borehole, the second end of the second borehole extends to the first borehole, and the second portion of the second borehole is in fluid communication with the first borehole.

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.

摘要： A coaxial circulation power generation device includes a moving medium reservoir adapted to be located in a pit formed in a heat source zone, a moving medium supply unit for supplying the moving medium to the moving medium reservoir, and a power generation unit for generating electricity from a driving force of the moving medium flowing between a low-temperature zone above and the high-temperature zone below the moving medium reservoir. The moving medium reservoir has an outer pipe connected to the moving medium supply unit and an inner pipe for circulating the moving medium, and the outer pipe and the inner pipe installed in the moving medium reservoir includes rotor blades that rotate in opposite directions with respect to a flow direction of the moving medium.

摘要： A geothermal system includes a wellbore with a borehole extending from a surface into an underground reservoir of magma. A chamber is located within the borehole and extends at least partially into the underground reservoir of magma. An inlet conduit allows flow of heat transfer fluid from the surface and into the chamber. An outlet conduit allows flow of heated heat transfer fluid from the chamber toward the surface.

摘要： Systems and methods for generating and a controller for controlling generation of geothermal power in an organic Rankine cycle (ORC) operation in the vicinity of a wellhead during hydrocarbon production to thereby supply electrical power to one or more of in-field operational equipment, a grid power structure, and an energy storage device. In an embodiment, during hydrocarbon production, a temperature of a flow of wellhead fluid from the wellhead or working fluid may be determined. If the temperature is above a vaporous phase change threshold of the working fluid, heat exchanger valves may be opened to divert flow of wellhead fluid to heat exchangers to facilitate heat transfer from the flow of wellhead fluid to working fluid through the heat exchangers, thereby to cause the working fluid to change from a liquid to vapor, the vapor to cause a generator to generate electrical power via rotation of an expander.

摘要： In some implementations, a plurality of thermoelectric devices may be arranged to cool one or more components of a downhole drilling component during drilling operations. A current can be applied to one or more thermoelectric devices to generate a cooling effect. The thermoelectric devices can be located and arranged so that they cool some or all of a bottom hole assembly or components thereof, such as one or more sensors, batteries, processors, electrics, and the like. The thermoelectric devices also may be located and arranged to cool sensors, batteries, other downhole components, and/or drilling mud in a wellbore during drilling operations. A plurality of thermoelectric devices may be used to generate electric power downhole from a temperature difference. The electric power may be used to power sensors, processors, charge batteries, and be used by one or more downhole electric components, such as those in a bottom hold assembly. One or more thermal storage devices may be used with the thermoelectric devices to store thermal energy for use when needed. A control system may be used to control the activation and/or deactivation of one or more thermoelectric devices to provide cooling when desired.
