Secondary tectonic belt is the focus of oil and gas exploration, because it controls the conditions of oil and gas traps directly. Raoyang sag experienced several tectonic movements, and there are great differences between deep and superficial feature, so it is important to research from different periods. Divide Raoyang sag from different periods into buried hill tectonic belt and Paleogene tectonic belt based on gravity anomalies, fracture characteristics, tectonic styles, etc. There are 12 buried hill tectonic belts including fault-block type, residual hill type and fold type, and 13 Paleogene tectonic belts including fault belt and anticline belt. Buried hill tectonic belts are controlled by deep faults, and paleogene tectonic belts are controlled by different basal activity, cover slip, reverse traction etc.
