An Approach to Oil-controlled Model of Local Structure of Putaohua Oil Layer in the Sanzhao Sag, oft-com:office:smarttags" />SongliaoBasin oft-com:office:office" />
Based on initial potential data of nearly 4000 production wells and static geologic material including the structure, logging interpretation, sedimentary microfacies and types of abandoned wells, oil—water distribution regularity in the Putaohua oil layer in the Sanzhao Sag, Songliao Basin, was systematically analyzed. In similar conditions, oil-control capacities are weakened from horst fault-block reservoirs→antithetic normal fault structural nose reservoirs→herringbone antithetic normal fault reservoirs→fault—microstructure reservoirs→fault—lithologic reservoirs, lithologic reservoirs→ other reservoirs.
