摘要

Bozhong sag,as one of the rare rich exploration potential of oil and gas. In hydrocarbon generative sag in east China,has a huge this paper, the characteristic of each tectonic unit＇s distribution and their fault development in Bozhong sag and its vicinity are systematically analyzed; and it is showed that the tectonic belt which center is Bozhong and Bodong sags has a ring structure characteristic. Therefore, we propose a new concept, i.e., Bozhong ring structure belt. Further analysis on the ring structure＇s genesis shows that it was caused by deep thermal structure activity （the up willing of mantle plume） during the Late Mesozoic and Eocene. In the new idea of ring structure, Bozhong and Bodong sags are regarded as a whole hydrocarbon kitchen,and the petroleum geology of Bozhong ring structure is also discussed, so as to the revelatory function of the new idea to the hydrocarbon exploration can be obtained.
