     East Structure 2 in Nanpu Sag is the external potential-expanding area of the oil and gas exploration, but the complex geological conditions result in the lower success rate of the petroleum drilling. The studies on the features of petroleum migration transportation and the conditions of the hydrocarbon preservation show that the hy- drocarbon accumulation is mainly controlled by the following seven factors： the trap configurations, fault combina- tion patterns, the properties of the faults connected with the oil source rock, trap-controlling fault types, the broken and connected thickness of the cap rocks, sand-formation ratio and the lateral sealing property of the faults. As the oil-bearing property of the fault traps is generally influenced by many factors, the comprehensive evaluating method of the above characteristic is established. Combined with the data of the drilled fault traps enriched or much en- riched with oil and in failure, the optimizing standards of the fault-trap evaluation are calculated and furthermore the comprehensive evaluation is engaged for the fault traps in Guantao, East Member 1 and Member 2 Formations.
