According to the identification of the low resistivity and heavy oil reservoirs in Lukeqin block,the analysis for origin of the low resistivity and heavy oil reservoirs are carried out.The variation of lithology and physical property are internal cause,yet the special accumulation mechanisms for heavy oils in Lukeqin block are external cause.Based on the analysis result,the authors established a series of logging identification methods,such as dual porosity overlay method,normal distribution method and dual electric method.This set of method has been applied to Lukeqin block and the correspondence of logging interpretation is improved greatly.
