通过对深凹区岩性油藏成藏条件的分析认为:沉积控制了深凹区岩性油藏的空间分布;三角洲前缘发育优质储集体及优质烃源岩;湖侵体系域是优质烃源岩发育的有利层位,也是油气富集的有利层位。以此指导泌阳凹陷深凹区岩性油藏勘探,选择泌阳凹陷较大型沉积体系——侯庄三角洲前缘、古城三角洲前缘及平氏扇三角洲前缘为岩性油藏勘探突破点,其湖侵体系域为岩性油藏勘探突破的层系。在侯庄三角洲前缘安店地区泌354井及多物源交汇处的毕店地区泌359井取得新突破,打破了深凹区油气勘探的阻滞局面。
Based on the analysis of reservoir forming conditions in deep-seated lithologic reservoirs, it is believed that sedimentation controls the spatial distribution of lithologic reservoirs in deep depressions, high-quality reservoirs and high-quality source rocks in the delta front, and high- The favorable horizon for source rock development is also a favorable horizon for hydrocarbon enrichment. This will guide the exploration of lithologic reservoirs in the deep depression area of Biyang depression, and select the larger depositional systems in the Biyang depression - the front of Houzhuang delta, the front of the ancient city delta and the front of the Pingshi fan delta as breakthrough points for exploration of lithologic reservoirs , Whose lacustrine system tract is a layer of exploration and breakthrough of lithologic reservoirs. In the Houzhuang Delta front Anting 354 wells and multi-material source of the junction of the reservoir made a new breakthrough 359 well, breaking the deep depression oil and gas exploration blockade situation.
