摘要
Abstract
Based on the massive core data and analysis methods such as scanning electron microscope .casting thin sections and routine mercury injection, detailly studies the reservoir characteristics of Chaiyao Area. The results indicate that Chang 6 reservoir mainly is a set of oyster gray-celadon feldspar fine-sandstone, secondly for powder-fine and system-fine ar-kose. Reservoir in this region is super-low permeability reservoir and the pore mainly be divided into primary pore, secondary pore, authigenic mineral intergranular micropore and mi-crofissure. The pore type is mainly intergranular pores. The pore throat sorting features is good and reservoir diagenesis types mainly includes compaction, cementation, dissolution and fracture diagenesis,which have significant effect on the developing of pore and physical properties.关键词
