Abstract

Abstract:

Based on the analysis of various data such as casting sandstone thin section,scanning electron microscope (SFM) and X-ray diffraction (XRD),this paper summarizes the petrological and mineralogical charaeteristics,diagenesis and its evolution of the Fuyang reservoir in the Songliao Basin,and studies the relationships between the diagenetic evolution and the physical and oil-bearing properties of sandstone carrier beds.Comprehensive study shows that the Fuyang reservoir is characterized by deep burial depth and strong diagenesis,and the diagenetic evolution controlled the physical and oil-bearing properties of the sandstone carrier beds and directly influenced the patterns of hydrocarbon migration.

Key words: petrological and mineralogical characteristics, diagenesis, physical property of sandbody, oil-bearing property, hydrocarbon migration, Songliao Basin
