摘要
According to the characteristics of complicated reservoir architecture of braided river and based on the basic principle of sedimentology and high resolution sequence stratigraphy,sedimentary origin of interlayer and interbed were analyzed and a method was proposed for predicting impermeable layer between wells.The results show that abandoned channel,interbar mud,fall silt and overbank are main origin types in barrier and interbed construct.Preservation of muddy deposition is closely related to accommodation space and sedimentary alimentation.Based on analysis of deposit genesis,shapes of different interbed types of mud were described according to single well log interpretation and well correlation.And sedimentary model of barrier and interbed was developed.Furthermore,the sedimentary model can be used in constructing training image after optimal selection.Prediction of barrier and interbed achieved by multi-point statisctics can effectively reflect the geometric morphology and distribution of interbed,which is more consistent with the sedimentary model of the braided river.
