Title: High-Resolution Sequence Stratigraphy Division and Research of Microfacies of Putaohua Reservoir in Talaha-Changjiaweizi Area
Abstract: Using core and well logging and seismic data,with high-resolution sequence stratigraphy principle as a guide,and combined with continental sequence stratigraphic characteristic,Putaohua reservoir in Talaha-Changjiaweizi area of Songliao basin was divided into 1 long-term base level cycle and then subdivided into 5 medium-term base level cycle and 25 short-term base level cycle,and sequence stratigraphic framework are set up.Based on comprehensive analysis of the core and well log log facies patterns of the area are eslablished and the corresponding microfacies map are dram.The vertical sequence of microfacies and percentage of sand in formation reveals that the region is mainly affected by two provenance,the near provenance from west and the far provenance from northeast.Channel and sheet sand are sweet reservoir.Distribution of sand is controlled by provenance distance and palaeogeomorphology.
