Description technique of channel sand body of upper Guantao formation in Feiyantan-laohekou area;

Method of identifying oil-bearing ability in channel sand body;

Using seismic attributes to identify channel sand body;

Control of base level cycles on channel sand geometry: A case study on Zao Ⅱ-Ⅲ reservoirs,Zaoyuan Oilfield;

Identification of channel sand in three-dimensional seismic data;

Reservoir prediction technique of channel sandbody and its application in Daqing peripheral oilfields;

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.

Based on previous data, this paper sums up the reflection texture and the variety of amplitude of the river sandstone body in a d.

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.
