英文摘要：

This paper proposed the technical ideas and research prospect of petroleum transportation system based on the knowledge of previous findings and the authors＇ years of research work in this filed. The key technology in this study was believed to contain the following： the paleopore reconstruction, the paleopressure reconstruction, the paleostructure reconstruction and the analysis of petroleum accumulation period. The research methods and the recent progress of the key technology were summarized. These research methods are proved to be important to restore the petroleum transportation system of accumulation period, determine the effective transportation system, and predict unknown oil-gas reservoir.
