摘要
根据与烃类流体包裹体相伴生的盐水包裹体的均一化温度，结合典型井的埋藏史、热史确定了王集—新庄地区成藏期次和时间：早期油气成藏期主要发生在核一段末期—廖庄组沉积期；晚期油气成藏期主要发生在廖庄末抬升期，是形成现今油田的主要成藏期。油气主要运移期应早于王集—新庄地区主要断裂的形成期。断层的形成导致原生油藏的破坏和再分配，也为核三上段生成的油气提供了运移通道和聚集场所，在核二段形成浅层次生油藏。根据含氮化合物油气示踪及区域地质背景认为，油气运移路径为南侧深凹成熟烃源岩—王集—断层（砂体）—新庄地区，当遇到圈闭时聚集成藏。
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 ＆ 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 Formationmthe 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.
