摘要
本文讨论了制约大中型油气田分布的一级控制因素:同位素地球化学急变带及太平洋型块体;并以渤海湾盆地(特别是辽河油田)、南方海相油气区为例讨论了上述关系;从Pb,Sr,Nd同位素证据论述了深源作用对油气生成的影响。根据上述观点,本文认为中蒙古地体边界将是中国大陆未来极有油气远景的地区。
This paper discussed the first-order controlling factors of large- and medium-sized oil/gas fields: the rapid-change belt of isotope geochemistry and Pacific block. The relationship has been discussed on the example of Bohai Bay Basin (especially Liaohe Oilfield) and South China marine oil/gas area. The influence of the deep origin on hydrocarbon generation has been studied in accordance with Pb, Sr and Nd isotope characteristics. Therefore, this paper thinks the boundary of Sino-Mongolia Palaeoterrain is the most prospective area for the petroleum exploration in China mainland in the future.
