Abstract:

The tight sandstone samples from Fuyu oil layer in Daan oilfield of Songliao basin were studied. In order to further study on the mechanism of seepage, a 3D digital core model with real pore throat structure was constructed by combining VGStudio MAX with Avizo, which has the advantages of non-destructive to samples, visualized results, and abundant data. Combining with ESEM Maps image splicing technology, the casting thin sections, and a constant speed mercury penetration analysis, the micro pore structure quantitative characterization of Daan oilfield was studied in Fuyu oil layer in the southern Songliao basin. The research showed that at micro-scale, the reservoir space types are mainly dissolution pores and micro cracks, the samples of different porosity and permeability have different pore throat size.The pore structure morphology is characterized by the two main forms of globular and stripped, and their pore throat distribution are two forms of contiguous and isolated; at nanoscale, reservoir space types are dissolution pores with mineral particles inside or on the surface and micro cracks, the pore throat morphology is characterised by the two forms of small globular and tubular, and the micro cracks have very good connection with nanoscale pore. Narrow throat radius is the main cause of low permeability of the samples.

Key words: Daan oilfield, Fuyu oil layer, X-CT scanning technique, tight sandstone, microscopic pore structure, digital core
