利用储层流体包裹体和原油地球化学资料，结合钻井地质和测试分析，对泌阳凹陷古城油田的油气来源、成藏期次、成藏过程和成藏模式的研究结果表明，东南深凹区核三下、核三上亚段烃源岩沿着古城油田北西构造抬升方向顺层两期供油，其中廖庄组沉积末期是油气大规模充注成藏时期。核一段沉积末期，泌阳凹陷东南部深凹区核三下亚段烃源岩达到生排烃高峰，油气从深凹（高势区）沿古城三角洲砂体进入古城鼻状构造（低势区），形成一定规模的古油藏；廖庄组末期构造抬升和断层活动，古油藏遭受一定破坏，同时核三上亚段烃源岩达到生排烃高峰，大规模成熟油气沿古城三角洲砂体横穿断层形成断阶式向上聚敛成藏。

The oil resource, hydrocarbon accumulation period, hydrocarbon accumulation process and hydrocarbon accumulation model for Gucheng oil field in Biyang depression were studied using the data of the seismic, geological well measurement, DST, fluid inclusion of reservoir and analysis of petroleum geochemistry. The results show that the source rocks of the upper member and lower member of Eh3 southeast depression provide oil and gas to respective formations, along southwest that is tectonic uplift direction in Gucheng oil field. There are two periods of hydrocarbon accumulation. One key period is in the end of liaozhuang group. At the end of Eh1, the source rock of the lower member of Eh3 southeast depression reached the peak of hydrocarbon generation, and hydrocarbon migrated from southeast depression into structural nose of Gucheng oil field along deltatic sand body, can form a certain scale of fossil oil accumulation. At the end of liaozhuang group, fossil oil accumulation suffered from some degree of destruction due to tectonic uplift and fault activity, and that the source rock of the upper member of Eh3 southeast depression reached the peak of hydrocarbon. Large mature hydrocarbon crossed fault along delta sand body, forming convergent stepladder type of hydrocarbon accumulation model.
