通过借助钻井、地震、重力、磁力资料，对背斜的形态、展布及基底响应进行研究。探讨青海柴达木盆地东部三湖地区生物气藏热力背斜的构造特征及对生物气藏的贡献，背斜的形成机制及与气藏的关系。认为三湖地区热力背斜生物气藏背斜构造的发育、发展对生物气的生成、运移和聚集起着积极的建设作用。深部断裂与岩浆活动是形成热力背斜的地质基础，通过与此相关的信息，为生物气藏的勘探提供了一条新途径。 Research on anticlinal forms, spreads and substrate responses by drilling, seismic, gravity, and magnetic data. This paper discusses the tectonic characteristics of the thermal anticline in the biogas reservoir in the Sanhu area, eastern Qaidam basin, Qinghai, and its contribution to biogas reservoirs, the formation mechanism of anticlines and its relationship with gas reservoirs. It is considered that the development and development of the anticline structure of the thermal anticline in the Sanhu area play a positive role in the formation, migration and accumulation of biogas. Deep faults and magmatic activity are the geological basis for the formation of thermal anticlines. Through the related information, this provides a new way for the exploration of bio-gas reservoirs.
