摘要
ASPE is one of the advanced technologies applied in reservoir micro-pore structure quality determination and audiovisual analysis.With the application of this technology,the pore structure of Chang 2 reservoir in Zhanghan Area of Dingbian Oilfield is analyzed and the influential factor of pore size and pore volume,throat size and throat volume on microcosmic pore structure are studied in this paper.Some important parameters such as the pore and throat sizes and their distribution frequency have been obtained.The analysis has demonstrated that the width of its seepage path extends with the extension of effective throat radius.The discrepancy of different level permeability of low permeability reservoir is mainly reflected in the throat size and distributioa The throat characteristics of the low permeability reservoir are the crucial factors that decides if the physical quality is good in low permeability layer.Different permeability of reservoir is decided by different throat radiuses.Pore-throat ratio has prominent influence on filtration characteristics,microcosmic distributed characteristics of remaining oil and displacement efficiency.
