摘要
There are two source rock beds, the lower Es1 and Es3 Formation, in Raoyang Sag of the Bohai Bay Basin. Based on saturated hydrocarbons chromatography and chromatography-mass spectrometry analysis of crude oil and source rocks, the relationship between Neogene crude oil and Paleogene source rocks was studied in the Raoyang Sag. Research has shown that Neogene oil in the Raoyang Sag mainly came from the lower Es1 source rocks, with the character of the nearest transportation. Affected by the distribution of source rocks, maturity and structure, Neogene oil mainly came from lower Es1 source rocks in the near oil-generating trough. In Wuqiang-Yangwuzhai area, hydrocarbon source rocks are not in oil-generating stage, Neogene oil mainly came from special lithologic section of the upper Es3.
