Abstract:
Oil-gas potential is one of the important parameters for evaluating reservoirs.There is noticeable pertinence between gas logging data and oil-bearing reservoirs.Gas logging combined with parameters was extracted based on R-factor analysis,and the weights were ascertained based on the variance of gas logging combined with the parameters.Gas logging combined with parameters of tested reservoirs was considered as a reference series and unknown reservoirs were taken as comparison series.Correlation function of tested reservoirs and unknown reservoirs was established.Oil-gas potential of unknown reservoirs can be identified based on the light of maximum subject degree.The case suggests that the method is simple in calculation and the result is reliable.
