摘要

According to the homogenization temperature of the brine inclusions generated with hydrocarbon fluid enclosures and integrating with the buried and heat histories of the typical wells, the period and times and time of reservoir formation in Wangji-Xinzhuang region are determined： early petroleum reservoir mainly formed in the sedimentary periods from late period of He No. 1 Interval to Liaozhuang Formation; late one principally happened in the rising period of late period of Liaozhuang Formation, the key reservoir forming period of the current oilfield. The main migration period of the oil and gas should be earlier than the forming period of the key fractures in Wangji-Xinzhuang region. The fracture generation results in the damage and redistribution of the primary oil reservoirs and furthermore provides the migration channels and enrichment space for the petroleum generated in He No. 3 Upper Interval. At the same time, shallow secondary oil reservoirs are generated in He No. 2 Interval. According to the petroleum trace of nitrogen-bearing compound and the background of regional geology, the migration path is from the mature source rock located in the southern deep sag to Wangji, faults （sandbodies） and Xinzhuang region, finally the petroleum reservoir formed whenever it encountered with the trap.
