The sedimentary microfacies analysis in the deep water with no or less wells is often confronted with the difficulty of low core data,no outcrop,and excessive well spacing.In order to solve these problems,it is necessary to use well-log and seismic data method and detailed seismic reflection characteristics and establish the relationship between seismic microfacies and sedimentary microfacies so as to guide sedimentary microfacies study and predict favorable reservoir distribution.Based on lobes of submarine fan in a deep water oilfield of West Africa,the authors established a microfacies model of three different sedimentary microfacies of the lobes of submarine fan by using the forward method of the seismic response characteristics of the different sedimentary microfacies.The well location suggestion is put forward,and this method is proved to have guiding significance for prediction of lobes of submarine fan in deep water oilfield with less wells.
