Study on Depositional Model of XinMiaoxi-Xinbei Region Fuyu Oil Layer in the Northern Fuxin Uplift of Songliao Basin

XinMiaoxi-Xinbei region fuyu reservoir of lower cretaceous quantou forth group sedimentary period develop large shallow-water delta sedimentary, which based on core data and logging information of 44 wells through the analysis of single well facies and logging facies analysis and the research of sedimentary microfacies. This area incude two kinds of subfacies,delta distributary plain,delta front.15 kinds of microfacies such as distributary channel,underwater distributary channel natural levee. Put forward the "source of phase controlled sand", "channel control reservoir" thought, predicted the main development zone of Fuyu reservoir of XinMiaoxi-Xinbei.
