摘　　要：扶新隆起带最早发现的扶余油田已经开发50年,是油田勘探、开发的老区,勘探程度较高。近年来,通过对扶新地区岩性油藏成藏条件分析及岩性油藏识别、改造技术运用,勘探成果不断扩大。扶新隆起带在继承性发育的古隆起背景上,大面积叠置"弯月形"河流相砂体,在环绕古隆起的"富油凹陷"共同配合下具备超大型岩性油藏形成条件。在该认识的指导下,充分应用三维地震储层预测技术、沉积微相技术精细刻画储层,并应用大型压裂及水平井技术,在扶余、新立等老油田周边地区,不断发现了新的油藏;在老油田扶余油层下部,杨大城子油层等新层系逐渐被揭示,储量规模超过1×108t。The Fuyu Oilfield, the first oilfield discovered in Fuxin Uplift, has been developed for 50 years, and the exploration degree is relatively higher. In recent years, more and more exploration results are obtained, with the analysis of reservoir-forming conditions of lithologic reservoirs and the application of reservoir lithology identification and modification technologies in the region. Paleouplifts developed in the Fuxin uplift zone, and 'crescent-shaped' fluvial sand bodies are overlaid by a large scale, and 'oil- rich sags' are distributed in the surrounding areas of the paleouplifts. So the Fuxin uplift zone has favorable conditions for the formation of super large lithology reservoirs. New oil reservoirs are discovered increasingly in the surrounding areas of the old oilfields of Fuyu and Xinli, based on the full application of the 3-D seismic reservoir prediction technology and the sedimentary microfacies technology as well as the large-scale fracturing and horizontal well technology. New layers including the Yangdachengzi layer are revealed gradually below the Fuyu Oilfield, with reserves exceeding 100 million tons.
