Based on investigations of accumulation types and distribution regularities in the Dawanqi oilfield,it is pointed out that,this oilfield is controlled by various geo-factors and characterized by multiple trap and reservoir types.

Dawanqi Oilfield is a typical unconsolidated sandstone reservoir in the Tarim Basin,whose majors located in the Quaternary and the Kangcun formation of Neogene.

On the basis of stratigraphic correlation, the characteristics of reservoir rocks of the Kangcun Formation, origin, types and features of sand bodies, pore types and textures of reservoir rocks and distribution characteristics of the reservoir in the Dawanqi oilfield have been intensively studies.

Dawanqi oilfield is a secondary reservoir formed through gas diffusion, which is an example in much extreme condition.
