| Abstract: | Using impregnated thin section,scanning electron microscopy,cathode luminescence and porosity and permeability test,this paper studies the petrography,pore type,physical properties,as well as diagenesis of sandstone reservoirs of the Neogene Shangganchaigou Formation in the Qianxi area of the northern Qaidam Basin.The reservoir dominantly consists of lithic arkose and feldspathic litharenite with low textural and compositional maturities.Intergranular and intragranular dissolved porosities are main pore typ... |
