Control of sequence stratigraphy on the reservoir of Yanchang Formation in Fuxian area, northern Shaanxi

A key factor controlling the oil-gas exploration of Yanchang Formation in Fuxian area is the sequence stratigraphy of the reservoir. It has been found that sequence stratigraphy ha controlled the development and distribution of reservoir rocks of Yanchang Formation area, and the physical property of reservoir is affected by the boundaries and depositional system tracts of sequence. Therefore, the development and distribution of reservoir has been apparently controlled by the sequence stratigraphy of Yanchng Formation in Fuxian area.
