Gas exploration potential of tight carbonate reservoirs:A case study of Ordovician Majiagou Formation in the eastern Yi-Shan slope,Ordos Basin,NW China
On the basis of comprehensive analysis of drilling, gas testing, laboratory analysis and testing data, the characteristics and genesis of tight carbonate reservoirs in Ma5_(1+2) Member of Ordovician Majiagou Formation, eastern Yi-Shaan slope, Ordos Basin were examined, and the potential of natural gas exploration and development were analyzed. The tight carbonate reservoir is defined as the reservoir with a porosity of less than 2% and permeability of less than 0.1×10~(-3) μm~2. The Ma5_(1+2) reservoirs are...
