论文从地质力学基础理论出发,分析探讨了我国生油岩层的形成条体以及在地壳运动、气候变迁和海水进退控制下古生代、中新生代生油岩层的时空分布规律,认为早古生代震旦纪、寒武纪、奥陶纪及晚古生代中、上石炭统和二叠统的海进层是古生代最有意义的生油岩层。中下三叠统、中下侏罗统、老第三系下部、新第三系下部的海相、陆相盆地沉积地层是中新生代的良好生油层,并根据我国大陆地质构造的演化程式指出,滇、黔、桂及南疆;渤海湾、黄海、东海、南海及柴达木、塔里木盆地西南部、伦坡拉盆地西部地区,是今后分别寻找古生代、中新生代油气的有望地区。
Based on the basic theory of geomechanics, the paper analyzes the formation of oil-bearing strata in China and the spatial and temporal distribution of Paleozoic and Meso-Cenozoic oil-bearing strata under the control of crustal movement, climate change and seawater advance and retreat. It is believed that the Early Paleozoic Sinian In the Cambrian, Ordovician and Late Palaeozoic, the Upper Carboniferous and Permian marine formations are the most significant oil-bearing formations in the Paleozoic. The middle and lower Triassic, Middle-Lower Jurassic, the Lower Triassic, the Neogene Lower Triassic marine facies and continental facies sedimentary strata are good Meso-Cenozoic oil reservoirs. Based on the evolutionary process of continental geology in China It is pointed out that Yunnan, Guizhou, Guangxi and southern Xinjiang; the Bohai Bay, the Yellow Sea, the East China Sea, the South China Sea and the Qaidam, the southwest of the Tarim Basin and the western part of the Lunpola Basin are the promising areas for the future exploration of the Paleozoic and Mesozoic-Cenozoic hydrocarbons respectively.
