Abstract

The Maichen Sag, situated within the Beibuwan Basin, holds significant potential for the exploration and utilization of deep bedrock geothermal resources. Unlike conventional geothermal reservoirs, the geothermal energy in the Maichen Sag is derived from sedimentary basins and fractured crystalline basement rocks. With temperatures exceeding 150°C at depths of 3 to 5 kilometers, these reservoirs offer a sustainable and reliable source of energy. This article examines the geological characteristics of the Maichen Sag, the exploration techniques employed to delineate its geothermal potential, and the opportunities and challenges associated with its exploitation. By tapping into these deep-seated resources, the region can reduce its dependence on fossil fuels, mitigate greenhouse gas emissions, and pave the way towards a greener and more sustainable energy future.
