摘要：
To reveal distribution characteristics and complex connectivity of fluvial sandbodies, plane distributions of fluvial deposited sandstone in the Ng 2 3 of Guantao Formation have been finely depicted using logging data and 90-degree phase stratal slices. The controlling effects on fluid motionof the reservoir's internal structure have also been analyzed according to dynamic development information. Our results show that a 90-degree phase transformation of the 3D seismic data in Kongdian Oilfield can achieve a better logging lithology calibration. The analysis of stratal slices shows thatin the Ng 2 3 deposited in the complex meandering belt are point bar, channel, muddy channel and floodplain deposits. The complex meandering belt is formed by the amalgamation and superimposition of multi-channel deposits and its internal structure has obviously controlled fluid motion in the reservoir. These areas are the target areas for adjusting development measures and improving oil recovery. © 2018, Periodical Office of China University of Petroleum. All right reserved.
