Abstract:

By the analysis of sources direction, sedimentary microfacies, sandstone distribution, adopting qualitative parameters,i.e., permeability mutation coefficient, permeability dash coefficient, permeability graded difference, permeability equal coefficient etc., the heterogeneity of from one to six sand beds of the E13in the west tract of gasikule oilfield is systematically studied in this paper. The results of study show that the vertical and horizontal heterogeneity in the main belt of interdistributary river area is stronger than the heterogeneity in the marginal and the front and the intersection areas of interdistributary river area. Moreover, there is the vertical heterogeneity in the positive rhythmic reservoir which has binary structure.

Key words: sources direction, sedimentary micro-facies, interdistributary river area, heterogeneity, permeability mutation coefficient
