Abstract:

Low permeable oilfield of large shallow-water lacustrine basin in China is one of the important exploration areas.The characteristics,reservoir forming conditions and exploraiton difficulties of low permeability reservoirs are indicated systematically according to the study of Fuyang reservoir in Songliao Basin.By using geologic and seismic techniques association,the authors present a processing system of efficient prediction in development areas of major channal and relative oil enrichment areas, and form sucha set of exploration proposals and technique countermeasures as searching hydrocarbon-rich areas in hydrocarbon-poor area so flow permeable oil field.

Key words:  Ordos Basin, Yanchang Formation, lake basin evolution, unsymmetrical developping, southwest deposional system, northeast deposional system
