摘要
Reservoir heterogeneity is one of main factors that influence fluid distribution and migration of fluvial reservoirs. It also influences oil and gas exploitation result. The results are as follows：heterogeneity index is first computed in the work area which conquers the shortcoming of multi-parameter inconsistent characterization. Practice shows that heterogeneity index in terms of entropy’s theory can acts as important function in characterizing fluvial reservoir heterogeneity and in predicting distribution of remaining oil.
