Features of Karst Paleogeomorphology and Sedimentary Environment of Ordovician Majiagou Formation in Eastern Ordos Basin [PDF]
The formation and evolution of carbonate weathering crust-type reservoirs are closely linked to paleokarst processes. This study aims to restore and analyze the karst paleogeomorphology and sedimentary environment of the Ma2 and Ma3 sections in the eastern Ordos Basin, using the compensation thickness impression method. The Ma3 section is characterized

Genesis and pore evolution of dolomite reservoir in the Majiagou Formation, Ordos Basin, China
In gypsum–carbonate rock assemblages, multistage and complex fluids control the formation of dolomite reservoirs that are a focus of hydrocarbon exploration. It is difficult to determine the types of dolomite reservoirs and their formation mechanisms due
