The Jingbian Sansheng is a new exploration area. The reservoir of control factors should be further analyzed. Then there are all aspects of reservoir analysis in this thesis. In study area Chang2is the anastomosed stream of sedimentation volume, it can be divided into two tiny precipitation facie, one is riverbed stranded and batture the other is flood plain deposit. The greatest impact of Reservoir porosity on diagenesis are compaction and pressure solution, cementation and denudation. The reservoir space is main primary intergranular space,less vugular-solution space..The paper argues that quality reservoir is sand bodies in more than15meters, porosity greater than15.0%,permeability greater than3×10-3μm2.Flood plain deposit is the main of deposition in the sdudy area, sand bodies contiguous with well. Then the riverbed stranded and battur deposit sands are important basis for the relative quality of reservoir development. And diagenesis has a great influence on reservoir properties. Compaction is a major factor in reduced porosity and permeability, cementation have a dual impact on reservoir properties. Denudation can improve the reservoir of porosity and permeability.Nose like structure can control the oil and gas gathering and oil-water separator. However, it is impossible to control the distribution of quality reservoir.
