Study on Primary Controlling Factors to Carbonate Reservoir Physical Properties of Zhanazhol Oilfield

Abstract:

By the aid of such core analysis data as lithochemical data, physical property data, thin sections and capillary pressure curves, studies were made on the physical properties and its primary controlling factors of carboniferous carbonate reservoirs of Zhanazhol oilfield. The studies were focused on such aspects as lithology, void type, pore connectivity, developing degree of vugs and fractures and fracture type. The study shows that the reservoirs of KT-I are principally multiple void-typed with middle porosity and permeability, with lithology, developing degree of vugs and fractures and fracture type being the primary controlling factors to their physical properties, and that the reservoirs of KT-II are principally fracture-pore typed with low to middle porosity and permeability, with lithology, void type, pore connectivity and fracture type being the primary controlling factors.
