Abstract：There exists the reservoir with low resistivity in upper and lower layers in Es3 formation,Mazhai Oilfield. Computed oil saturation is lower than 500o and its bound water saturation is 600.and above in this kind of reservoir. Adding formation water with higher salinity, conductibility is increased and resistivity is decreased,formed the reservoir with low oil saturation and low resistivity. Based on the feature,we use natural gammaneutron logging and density logging to appreciate the formation parameters. We use analyzed results of drill cores and median grain diameter to compute bound water saturation of formation. The reservoir fluid dynamics is syntheticlly analyzed by using reservoir theory,the reservoir is appreciated by bound water saturation and formation water saturation. A set of formula and drawing board for interpretation has been created.
