N21 reservoir of Wunan Oilfield is of mainly delta front subfacies. The lithology consists mainly of siltstone and fine sandstones. The difference between lithofacies, lithology and physical property of the reservoirs govern the oil and gas accumulation level. Under the same lithology and lithofacies conditions, the oil-bearing saturation depends on the difference of physical property. With the analysis of the logging data, the production testing data, the core data, the water analysis data as well as the study of 4 -property (lithology, electrical property, petro-physical property and oil-bearing property) relations of the N21 reservoir, the model of well log鄄 ging data processing and interpretation has been established and the well logging interpretation standard has been determined.
