摘　　要：基于莺歌海盆地地热背景,从地热系统的水源、流体通道、热储和盖层4个方面系统地去评价红河断裂对其的控热作用。研究结果表明,通过水样、气样分析,断裂构造在地热水循环中起到重要的控制作用;红河断裂的差异变形显著影响裂隙型热液热储的平面分布范围和纵向发育深度的异质性;莺歌海盆地地热系统是以地幔热物质作为主要热源,红河断裂带和盆地内中央凹陷底辟带为主要通道,裂隙型热液热储和上部大面积水道、海底扇、三角洲等储集体为主要热储,莺歌海组巨厚泥岩为主要盖层。This study uses the geothermal background of the Yinggehai Basin to systematically evaluate the role of the Red River Fault in controlling the source of water,pathway of fluid,reservoir,and cap layer of the geothermal system.The analysis of samples of water and gas show that the fracture structure plays an important role in controlling the geothermal water cycle.The differential deformation of the Red River Fault significantly influences the range of planar distribution and heterogeneity of the depth of longitudinal development of rift-type hydrothermal reservoirs.The geothermal system of the Yinggehai Basin is grounded in thermal mantle material as the main source of heat,with the Red River Fault Zone and the bottom-penetrated zone of central depression in the basin acting as the major channels.Moreover,the rift-type hydrothermal reservoirs,upper large watercourses,submarine watercourses,submarine reservoirs and cap layers,submarine fans,deltas,and other storage groups in the upper part serve as the main thermal reservoirs,while the giant mudstone of the Yinggehai Formation acts as the main covering layer.
