The slope is major structural unit of half graben and also is main direction for regional oil gas migration and main oil gas accumulation zone. But comparatively speaking, the oil gas exploration on slope is more difficult by comparison with in central uplift and in other units, so that is an area needs to further strengthen exploration. According to seismic data and other real geological data in half graben widely developed in our east area, the paper categorized the slope and put forward a category plan, that is ' two categories and ten types ', and had a discussion on its petroleum geologic properties, appreciation and exploration thinking, which is in hopes of an aid to deep development of oil gas exploration on slope.
