Abstract

The OrdovicianMa 51 reservoir in northeastern Jingbian Gas Field in Ordos Basin is at the top ofweathering crust. The diagenesis is complex because of weathering and denudation in about 130 Ma. Based on the analysis of core and thin slice, it is concluded that the forming of Ma 51 dolomite reservoir is dominated by hypergene karstification, burial dissolution and mineral filling. The favorable diagenesis zones of Ma 51 reservoir are mainly in the midst-central south and west of the study area.
