Abstract：On the basis of the thin section observation, scanning electron microscopy analysis, and comprehensive analysis involving reservoir pressure coefficient, porosity type and size, throat features, and other characteristics of the data, it is found that the study area, Hutubihe Formation's lithologic reservoir is a Class I reservoir, and the reservoir possesses main characteristics, such as high porosity, high permeability, low displacement pressure, and a large throat. Compaction of the sandstone reservoir in the study area is from moderate-weak intensive. It is obtained from final study that although the content of the low degree maturity and the relatively poor ability plastic cuttings are higher, but the high-quality reservoirs are still able to form in the study area, the reason for that is mainly due to extensive development of high-energy micro-braided channel deposit, the mud content of high-energy micro-braided channel is lower, therefore the porosity and permeability is higher; the size of sand in the study area is mainly the lithic sandstone and fine particles, the larger particle size enhances the compressive strength of sandstone; the diagenesis is slow down because of the low geothermal gradient in the study area; the early hydrocarbon charging enhances the real capacity of the reservoir under the pressure, so that the original porosity can be preserved well; in the later stage, the structure in the study area is stable, big fault activities that do damage to oil and gas reservoir never happen, and the primary pores are not destroyed.
