摘　　要：作为南海形成与演化地球动力学背景研究的一部分,南海大地热流测量一直是一项重要的工作.现有数据分析表明,南海热流值分布总体上反映了其区域大地构造背景.随着深水区油气勘探的重大发现,南海现今地温场的研究正不断深入,研究的区域亦从浅水区扩展到深水区,同时,基于油气勘探的需要,盆地热史恢复的工作逐步展开,热史恢复也得以进行.相关的地热研究成果已被用于预测构造带分布、约束构造演化史、探索深部地球动力学机制、评价油气生成潜力等诸多方面.然而,由于地理位置的特殊性以及原始资料的缺乏,南海地热研究还存在热流数据分布不均,岩石圏热结构及热史研究不深入,系统的区域对比研究缺少等问题.本文综述了国内外近些年关于南海地热研究的进展,并在此基础上对未来的研究提出了一些建议与展望.Heat flow is one of the important parameters for the study of geodynamic setting related with the origin and evolution of the South China Sea （SCS）. Data analysis had demonstrated that the heat flow distribution could generally reflect the regional tectonic background. Along with the great achievement in oil and gas exploration in deep water area, the research on present geothermal field of the SCS is developing with the study area extended to the deep water area from the shallow water area. Moreover, the thermal history reconstruction is accordingly being carried out due to the oil and gas exploration requirement in deep water area. The geothermal research results of the SCS have been used for tectonic belts prediction, tectonic evolution constraint, geodynamic mechanism exploration, hydrocarbon generation potential evaluation and other aspects. However, there are still some defects such as uneven distribution of heat flow data, poor study on deep thermal structure and thermal history in the southern margin, lack of regional correlation study because of its particular geography and absence of data source. This study is aim to review the domestic and international research progress on geothermal field of the SCS, and put forward some suggestions and prospects on future study.
