Abstract: The theory of slope break is an advance of sequence stratigraphy applied in terestrial basin. This paper reviews the application of this theory to petroleum exploration and points out that slope-break zone can control the development of continental sequence stratigraphy, distribution of the depositional system tracts and sand bodies. Hence, the first lake flooding surface in terrestrial basin and the scope of distribution of its sand body and source rock can be determined by the theory of slope break. Slope-break zone could even control the hydrocarbon migration and accumulation. Based on these, this paper discussed the relationship between slope-break zone and non-structural reservoir and highlights how to apply this theory in prospecting of non-structural oil-gas reservoirs. It is concluded that the theory of slope break is a new thought of looking for non-structural reservoir.

Key words: slope break, sequence stratigraphy, terrestrial basin, non structural reservoir, subtle trap, petroleum exploration
