| Abstract: |
| The marine hydrocarbon source rocks in Erlian Basin are mainly composed of argillaceous rocks andcarbonate rocks deposited in a trough environment. According to the data of experimental geochemistry such asresidual , carbon isotope of kerogen (δ13C) and GC-MS analysis of hydrocarbon in outcrop samples from basin margin, the abundance, types and thermal evolution extent of organic matter from Carboniferous-Permian marine source rocks are presented. The TSM basin modeling technology was applied to calculate hydrocarbon-generating intensity on the basis of thermolysis loss of organic matter abundance and correction of surface weathering loss, and combined with the geochemistry characteristics of hydrocarbon samples with high thermal evolution and low abundance. By the integrated analysis of geochemistry characteristics and hydrocarbon-generating intensity, it is included that Carboniferous-Permian source rocks in Erlian Basin have low- to medium-graded hydrocarbongenerating potential. |
