Establishment of Isochronous Stratigraphic Framework of Fuyu Oil Layer in Toutai Oil Field and its Significance

摘要

Based on the detailed core data and logging data from Toutai oil field and applying correlative technique of fluvial facies reservoir, through guiding wells selection, key beds determination, progressive oil layer subdivision of all wells, fine stratigraphic classification and correlation are carried out. The Fuyu oil layer in Toutai oil field is divided into 3 sand groups, 18 sublayers and 37 sedimentary units, consequently, monosandbody-scale isochronal stratigraphic framework is established, which can provide geologic basic data for further study on sedimentary inicrofacies, sand body distribution, oil and water distribution and favorable target prediction.
