Many fault traps occur in the Zhu 1 Depression in the Pearl River Mouth Basin because of well-developed faults. This paper used arithmetic products (SDD) of the shale content in fault rocks, the burial depth of fault rocks and the cosine of fault dip to quantitatively express the lateral sealing of faults indirectly, and applied products of the quotient derived from the division of the fault throw resulting from re-activities after the reservoir formation of fault traps by the ancient fault throw during the reservoir formation of fault traps and the frequency number of fault activities to quantitatively express the extent to which fault rocks were destroyed. The result showed that among the twelve fault traps to be drilled in the zone, five of them were less risky if drilled and the rest were too risky to be drilled.
