摘要
On the basis of hydrocarbon migration pathways and its time-space effectiveness in the southwestern part of the Gudao oilfield, this paper focused on kinematic and dynamic characteristics of hydrocarbon migration through the synthetical analysis of oil and gas show, fluid property and biomarkers. The research showed that the maturity parameter C29 sterane could effectively prove that hydrocarbon of the 3rd Member of the Shahejie Formation from the Bonan sag and hydrocarbon of the 1st Member of the Shahejie Formation from the Gunan sag are the two sources of this research area, which means the hydrocarbon of the 3rd Member of the Shahejie Formation from the Bonan sag migrated from the Gubei fault, the Guxi fault and other migrate factors, hydrocarbon of the 1st Member of the Shahejie Formation from the Gunan sag migrated from the Gunan fault belt and well-developed sands of this formation.
