Because of complex geologic characteristics of Fengfuchuan oilfield, it is difficult to identify sedimentary microfacies by conventional approach. In order to solve this problem, wavelet analysis technique was used to carry out stratigraphic division and establish stratigraphic sequence. Based on the grey system technique, the evaluation parameters, criterion and weight coefficient which are suitable for the study area were chosen to identify sedimentary microfacies. The result shows that the first using of wavelet analysis and grey theory to sedimentary microfacies identification in Fengfuchuan Oilfield achieved good results, and it provides a feasible method to sedimentary microfacies research and can service for development adjustment of oilfield.
