Separability of PI3₃ in X Block of Daqing Oilfield

Abstract:

This paper takes X block as the target area, on the basis of logging data, the core information, dynamic production information, with high-resolution sequence stratigraphy demonstrating two-separability of PI3₃ systematically from the angle of sedimentology, namely, this layer is a sedimentary complex of the two river stage. We have analyzed the characteristics of remaining oil in the compound sandbody. Each channel sandbody has its own respective characteristics in the vertical water flood. As a whole at the bottom, the extent of water flood is high, and it weakens gradually until non-flooded with the level raising. It provided the basis for the study of the single sandbody architecture and the advance of the recovery ratio.
