摘要
In view of the three types of river channel sandbodies in braided, meandering and distributary rivers at the late period of extra-high watercut of Daqing Placanticline oilfields, according to the data of modern sedimentation and field outcrop, and moreover the rich data of dense well patter, well logging and the performance, the structural types within the typical river channel sandbodies and the reservoir distribution modes are studied in detail. And furthermore the remaining oil distribution modes within the oil layers controlled by the structural types in the sandbodies are summarized.
