通过对辽河盆地西部凹陷深层石油地质特征的综合研究，搞清了本区深层构造及演化特征，揭示了深层沉积特征、砂体展布规律以及深层成藏的主控因素，分析了深层储集性能及孔隙演化规律。本区深层５０００ｍ以上烃源岩处于成熟阶段，生排烃时窗长，油源充足；深层储层以沙二段扇三角洲前缘砂体及沙三段湖底扇辫扶沟道和扇中前缘砂体储集性能最好，结合先进的储层预测技术发现和落实了清２０南等一系列构造及岩性圈闭，指出了下步勘探方向，为深层勘探的突破奠定了基础。
Through the comprehensive study of the deep petroleum geology in the western depression of Liaohe Basin, the deep structure and evolution characteristics of this area have been clarified, the characteristics of deep sedimentary deposits, the distribution laws of sand bodies and the main controlling factors of deep reservoir formation have been revealed. Performance and pore evolution. The source rocks above 5000m deep in this area are in maturity stage, and the time-window of hydrocarbon generation and expulsion and the oil source are abundant. The deep reservoirs are composed of sand bodies of the second member of the Shahejie fan delta, The margin sand body has the best reservoir performance. Based on the advanced reservoir prediction techniques, a series of structures and lithologic traps of Qing-20 South have been discovered and implemented. The exploration direction is pointed out, laying the foundation for the breakthrough of deep exploration.
