Structure Evaluation

It is of great importance in classifying reservoirs and establishing the relationship of pore structure and productivity for formation evaluation and reserves estimation. In this study, based on the morphological characteristics and the difference of pore structure evaluation parameters acquired from mercury injection capillary pressure (MICP) data, which were obtained from the experimental results of 20 core samples drilled from Chang 6 tight sandstone Formation of north Ordos basin, the Chang 6 formation is classified into three types, and the corresponding average MICP curves of every types are obtained. These were usable in determining the potential target formation and predicting the productivity in tight sandstone reservoirs.
