Controlling Factors of Physical Property of Tight Sandstone Reservoir of Fuyu Oil Layer in Daan Oilfield

Daan oil field is located in the secondary belt of Daan- Honggang terrace of the central depression area in the south of Songliao basin, and the study area is located on the deepest sub sag in Daan-Honggang terrace.Fuyu oil layer is the main layer series of development of the oilfield. The main controlling factors of the physical property of the tight sandstone reservoir of the Fuyu oil layer in Daan oilfield are studied based on measurements normal thin-sections, cast thin-sections, logging data, some other laboratory analysis data and previous research.
