Evaluation on Sealing Ability of Upper Paleozoic Caprocks Physical Property and Favorable Targets Prediction of Shiqianfeng
Formation in Shenmu Region, Ordos Basin

Abstract

Abstract: Based on the study of physical property sealing parameters such as displacement pressure, porosity, permeability,surface ratio, diffusion coefficient, etc.of Upper Paleozoic mudstones in Shenmu region, Ordos Basin, it can be concluded that physical property sealing ability is a key parameter that affects the upward diffusion and migration of natural gas. On the basis of the analysis on these physical property sealing parameters and diagenesis, etc., evaluation criterion is established for the physical property sealing ability of mudstones in this region.The plane evaluation shows the physical property sealing ability of He-8, He-7 layers in upper Shihezi Formation, and He-4, He-1 layers in lower Shihezi Formation are relatively strong, and the map is formed by choosing the representative displacement pressure parameter. In addition, combining the other factors, three type areas are predicted to be favorable for the reservoir-forming of Shiqianfeng Formation. Type I distributes at the east of Yulin area, while type II and type III distribute at the south of Hengshan County and at the north of Shenmu County respectively.

Key words: Ordos Basin, upper Paleozoic, physical property sealing, displacement pressure, caprocks
