  • Abstract

    Upper Paleozoic Petroleum System is an important exploration field in the Bohai Bay Basin.Many primary oil and gas reservoirs related to the Carboniferous Permian coal measure source rocks have been found,which shows a good exploration prospect in this field. Due to the strong orogenic transformation of the Paleozoic in the eastern Bohai Bay Basin and the South of Northern China area,the conditions of hydrocarbon accumulation are extremely complex. The continuous increase of reserves and production in this field is faced with a series of key geological problems and technical problems related to hydrocarbon generation and accumulation and resource potential. Based on the northern Bohai Bay Basin,focusing on the fine geological evaluation of coal measure source rocks,the process of multi⁃lay⁃ er hydrocarbon charging and accumulation,and the research and development of exploration and evaluation technology of primary oil and gas reservoirs in residual basins,the geological characteristics of the upper Paleozoic oil and gas res⁃ ervoirs in the northern Bohai Bay Basin are re understood,and the exploration potential is evaluated. The results show that the Carboniferous Permian coal measure source rocks generate both gas and oil,especially in the Taiyuan Formation,which is more favorable for the formation and preservation of hydrogen rich components in coal;The simula⁃ tion experiment of hydrocarbon generation kinetics shows that the coal measure source rocks of the Taiyuan Formation entered the threshold of oil generation and gas generation earlier, and have a better potential of oil generation and gas generation;The total gas generation of the Carboniferous Permian system on both sides of the Cangxian uplift is 56.17 trillion cubic meters,and the total oil generation is 2.063 billion tons,which improves the exploration potential of oil and gas reservoirs inside the buried hill. Based on the combination of reservoir anatomy and physical simulation ex⁃ periment of oil and gas filling,a multi⁃element differential enrichment model of oil and gas in the buried hill is con⁃ structed. It is proposed that the dominant thick reservoir near the transport channel,fault turning position and low an⁃ gle thrust fault transport conductor are the dominant migration and accumulation areas of oil and gas in the buried hill, which can effectively support the deployment of oil and gas exploration.
