Putaohua oil reservoir of Gulong Oilfield belongs to medium-porosity and low-permeability clastic reservoir. The comprehensive genetic analyses of the complicated reservoirs are conducted by lithology, physical properties, muddy, calcareous, residual oil and so on. The results show that there are 4 kinds of generated reservoirs. On the basis of the correcting model for these resistances, reservoir resistances have been corrected from three aspects of shaly, calcareous matters and thin layer, which increases the identifying model precision of oil and water layers by crossplot board method.
