Description

technical field

[0001] The invention relates to the field of heat measurement, and more specifically to a simulation system and simulation method for developing and protecting a thermal convection geothermal field. Background technique

[0002] According to the nature and occurrence state of geothermal resources, geothermal systems can be divided into five types: steam type, hot water type, ground pressure type, dry-hot rock type and magma type. Steam type and hot water type are collectively referred to as hydrothermal type, which are the main targets for development and utilization at present. Ground pressure type is relatively rare in nature, but its energy potential is huge. In addition to thermal energy, chemical energy such as methane is often stored. The mechanical energy caused by high pressure has great utilization value; the potential value of hot dry rock type and magma type is also great, but its development and utilization also need to improve the economic and te...

Embodiment Construction

[0060] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0061] Convective geothermal system (convective geothermal system) is that near-surface water penetrates deep underground through porous permeable channels, and encounters hot rocks in the depths, and then geothermal fluids such as water and (or) steam are driven upward by force, resulting in Convective circulation system. In the convective loop, the discharge to the surface or outflow from the rock formation is partially replenished from groundwater from atmospheric sources. In a hydrothermal convection system, most of the heat (and mass) is transferred by the convection process of liquid water and / or vapor through the high permeability rock mass. Hydrothermal convection systems can be ...
