Abstract: Division and comparison of sand body are important contents in field development. Sand body compar-ison is difficult because Ng5, Ng6 of Kengdong18+32 is meandering stream. This article depicts the sedimentationtype and feature of meandering stream in Kengdong18+32. The layer position is divided by means of marker bedand assisting marker bed. Time cell is determined by the way of sedimentation cycle and uniform thickness section,and defined with height unite area analysis. Finally, sand body comparison scheme is built. The article considersfeature of meandering stream sufficiently. It also interprets the effect of differential compaction on cut plane, sandbed compare graph of filled and normal river channel, superimpose or lower cutting comparison of thick sand andthin sand body from the view of the sedimentation feature of meandering stream. Then the article builds up the wayof sand body comparison of meandering stream. Fine sand body comparison and division provide reliable geologyfoundation for further geology research, numerical simulation and analysis of remaining oil.
Key words: meandering stream, thin sand body, comparison and division, cycle of sedimentation, equal elevation
