In order to improve the polymer flooding development effect of small channel sand reservoir, based on dynamic variable characteristics, different injection parameters and integrated adjustment method are adopted for different injection periods and sand body development degree.

The oilfield in the south of Daqing Changyuan characterizes the narrow sand body most of which distributes in the shape of straps or net structures.

Oil field with now permeable narrow sand body has the characteristic of small sand body, scattered distribution, less penetrated layer in single well and thin reservoir.

This paper takes Yushulin Oil Field, which is a super low permeable lithologic reservoir in the peripheral part of Daqing Oil Field, as an example and uses the geologic profiling of oil bearing sand body to propose a set of random simulation pattern optimized arrangement which is suitable for narrow channel sand bod

An algorithm is put forward which can be used to trace the boundary of the channel sandbody in fluvial facies reservoir.

Using the three-dimensional visualization software,we can accurately interpret structure and describe the forms of traps through showing the space of various attribute data of seismic data cube to composite fault and trace channel sandbody.
