In the process of long-term waterflooding development of sandstone oil fields, preferential water drive channels will be developed in the reservoir which cause uneven waterflood sweep and influence oil field development effect. Taking M-I-1 single sand layer in the Kumkol South Oil Field in South Turgay Basin, Kazakhstan, as an example, using logging interpretation, fine geological characterization, and reservoir numerical simulation method, this article studied static geological and dynamic development characteristics as well as control factor of preferential water drive channel of meandering river sandstone. In meandering river sandstone, the point bar sand is thick sand with lateral accretion shale beddings developing inside, so the injected water sweeps preferentially along the bottom part of the sand, causing the bottom part to be strongly waterflooded. And the bottom part of point bar sand is preferential water drive channel, which is strong water-intake (or strong liquid production) interval in injection water (production) profiles. Overbank sand is thin sand with low heterogeneity and therefore is non-weakly waterflooded, so overbank sand is not preferential water drive channel. The study confirms the fact that sandstone architecture control formation of preferential water drive channel and provides a basis for further potential tapping of meandering river sand bodies.
