Bitumen is universally distributed in the reservoirs of a large number of oil fields in the world. Many researches are focused mainly on the mechanism, genesis,and distribution character of the deposited bitumen. In a trap, solid bitumen can cause reservoir heterogeneity and form permeability barriers not related to depositional facies. When the precipitated bitumen fills pores totally, bitumen-sealed belts can be formed, and thereby hidden reservoirs formed. However, the occurrence of solid bitumen brings much difficulty in the decision of exploratory well sites, and prevents the prediction of favored intervals with the traditional geologic theories. The key to identify this sort of reservoirs is to find thesites of the bitumen-sealed belts. Based on the previous studies, this paper suggests three possible positions of bitumen-sealed belts of different genesis, and the most favoured exploration targets. More attention should be paid to the exploration when bitumen appears.
