Aim To recognize the complicated oil and water layers in Chang 2 oil-bearing formation of Donghan area in Dingbian oilfield. Methods Based on the conventional logging suite, with the result analysis of comparative experiment,adopting the methods of PSP-SP overlapping, crossplot stepwise discriminant analysis and PHC experiment. Results The overlapping is a quickly visual display of methhods which effectively distinguished the oil and water; the crossplot stepwise discrimiomt analysis can identify different kinds of oil and water, and the aocuracy grow with the data source;the PHC experiment is active and effective as it is independent of resistivity log parameters.Conclusion By the use of conventional well logging data,the para meters are appropriately selected and optimized the unconventionality oil and water layers are effectively distinguisbed, and the degree of accuracy of interpretation procedure has been improved.
