Daqing Oilfield Sanan Putaohua Reservoir Sedimentary Microfacies Research

Abstract:

Putaohua reservoir is the principal producing formation in the Daqing oilfield sanan block. The spatial distribution of single sand body is particularly important for the residual oil tapping in the middle-late stage of oilfield development. The paper studied sedimentary microfacies of Putaohua reservoir in the area, established high-resolution sequence stratigraphic framework of the area and a typical single sand body logging phase mode on the basis of logging features, finely portrayed single sand body type and spatial distribution on this basis, laied the solid geological foundation for the oilfield subsequent residual oil tapping, provided a scientific geosteering.
