Abstract

Abstract:

Three types of flow units are recognized in the reservoirs of Yushulin oilfield,and log interpretation models are built for porosity and permeability through standardization of log data,selection and processing of core data,and calculation of flow unit index (FZI).Accuracy of permeability interpretation is greatly improved when calculating reservoir permeability according to the flow units.Sample collection that reflects the internal relationship between log data and flow units is also obtained,realizing the extrapolation of optimal quantitative reservoir parameters from the cored wells to non-cored wells. Relatively accurate calculation of permeability is realized by applying different interpretation models to different flow units. The application of the method in 77 wells in the study area shows that it can reflect honestly the lateral changing pattern of reservoir parameters and offers gui-dance for determining residual oil distribution and adjusting development programs.

Key words: log parameter, flow unit, log interpretation model, Yushulin oilfield, Putaohua reservoir, Songliao Basin
