Reservoir Feature of the Middle-Deep Strata in Suning-Dawangzhuang District of Jizhong and Its Influencing Factors
Abstract: The reservoir physical characteristic and its influencing factors are studied in detail based on the core observation and the analysis of sedimentary microfacies and reservoir properties such as thin section, casting thin sections, mercury intrusion data etc. The research shows that the rock types of Suning-Dawangzhuang district of Jizhong are mainly siltstone and fine sandstone, which are characterized by fine grain size, medium-good sorting and sub-rounded. The ingredient of sandstone is mainly arcose. The reservoir physical characteristic is poor, middle-low porosity and middle-low permeability. The main pore type is secondary pore which is formed by the dissolution of feldspar and debris, the second is primary porosity. Reservoir space is influenced mainly by sedimentary process, diagenesis, and formation pressure. The research shows that the sandstone of highly dissolution and weak compaction in the middle of river has good reservoir properties.
