The black rock series called “Madian Formation”,which were at the bottom of the Cambrian System in southern North China Basin,were the most important marine hydrocarbon source rocks with the best organic geochemical evaluation and hydrocarbon shows.The formation,evolution and accumulation of oil and gas in Madian Formation would be investigated by microscopic characteristics,fluorescence characteristics,homogenization temperature and composition analyses of fluid inclusion in this paper,which could provide new information for decision on further natural gas exploration in southern North China Basin.The homogenization temperatures of primary brine-aqueous inclusions and organic inclusions were 115-300℃ and 108-220℃ respectively with the main peak value of 185℃.The inclusions contained higher content of reductive components,such as H2S,CO,H2 and N,and were divided into CO2type,high CO2 type,LH(light hydrocarbon)+CO2 type and LH type by C1-6/CO2 ratio.It was suggested by changes of abundance and type of organic inclusions that there are three times of hydrocarbon generation and expulsion process in the middle stage of diagenesis,late stage of diagenesis and tectonic stage after diagenesis.Therein,the tectonic stage was also peak of hydrocarbon generation and expulsion from Madian Formation,which was in early-middle Triassic with burial depth of 4 500-6 000m.The primary inclusions of Madian Formation mainly recorded hydrocarbon generation and expulsion process during high mature as well as over mature of thermal evolution,and the reservoir was evaluated by parameters of fluid inclusions as commercial gas reservoir or gas showing reservoir,while the secondary inclusions might record the fluid activity during the uplift denudation.Madian Formation in Mesozoic and Cenozoic sedimentary basin area is still a favourable target of natural gas for further exploration,which has good secondary hydrocarbon-generating potential in Yanshan and Himalayan periods.
