Abstract: In order to study the characteristics of glutenite reservoir, the data of core, casting thin sections, cathodoluminescence, scanning electron microscope and reservoir properties of glutenite of Cretaceous Xiagou Formation (K1g) in Ya' erxia area were studied to discuss the macroscopic and microscopic reservoir characteristics and influencing factors of clastic rocks. The results show that the K1g reservoir rocks are mainly composed of feldspathic lithic sandstone and lithic sandstone, and the fillings are mainly dolomites, with low texture and composition maturity. The pores are dominated by intergranular dissolved pores, intragranular dissolved pores, primary intergranular pores and super-macro pores,together with fine throat. The average porosity and permeability of the glutenite reservoir are 7.68% and 4.92 mD, respectively, showing the characteristics of low porosity and low permeability. The reservoir properties are controlled by sedimentation, diagenesis and tectonism. The favorable rock types are fine sandstone and pebbled sandstone, and the favorable sedimentary microfacies are mainly subaqueous distributary channel and mouth bar in fan delta front. Compaction and cementation make the reservoir properties poor, and dissolution of feldspar and carbonate and tectonism improves the reservoir properties. The study results can provide geologic basis for oil and gas exploration in this area.

Key words: “three-low”reservoir, air foam flooding, low temperature oxidation, Ganguyi Oilfield
