Abstract

Based on the analyses of geneses of reservoir sandstone and the favorable conditions of reservoir of Chang-3 oil formation,the genetic type of the reservoir sandbodies in this area can be divided into underwater distributary channel,combination of underwater distributary channel and mouth bars,mouth bars sandbodies.There are main four favorable conditions of reservior,they are oil-bearing sandbody underlying deepwater mudstone,nose-uplift on the background of monoclinal structure,top stratigraphic of changing.

Key words： Ordos basin; Yanchang formation; Geneses of reservoir sandstone; Favorable condition of reservoir; Characteristic of reservoir.
