三维模拟技术在地热开发中的应用现状与发展趋势OA

By integrating multi-source data such as geology,geophysics,and geochemistry,3D simulation technology can con-struct high-precision,visual 3D models of underground space,thereby significantly enhancing the information dimension and interpretation capability.Its important significance lies in the following aspects:it can greatly improve the accuracy of strati-graphic positioning and resource evaluation,optimize geothermal exploration deployment,thus enhancing the efficiency of geo-thermal development,and provide key decision support for the sustainable development of geothermal,and other related re-sources.This paper systematically reviews the current status and development trends of 3D simulation technology in geother-mal development and conducts a modular analysis of its core components,including key technologies such as 3D geological modeling and multi-physics field-coupling simulation methods.Then,combined with typical domestic and foreign cases,it elaborates on the practical application effects and experiences of 3D simulation in different geothermal scenarios,such as hot dry rock,hydrothermal geothermal systems,and enhanced geothermal systems(EGS).On this basis,it summarizes the main problems and challenges faced by the technology in practical applications,including insufficient data acquisition accuracy,difficulties in model calibration,large uncertainty quantification,and the integration of multi-directional and multi-scale technologies.3D simulation technology is fundamentally changing the mode of geothermal development and serves as the core engine for the digital transformation of the geothermal resource industry in the future.The future technological development di-rections in this field focus on cutting-edge innovation trends such as artificial intelligence-assisted modeling and inversion,the construction of full-life-cycle digital twin platforms,and multi-source data fusion and assimilation technology.
