摘　　要：对靖吴地区三叠系油气地质条件的重新认识促进了该区长7以下深层次油藏的石油勘探,先后发现了高44、新82及柳140-12等出油井点,同时试油获得较好的工业油流;而在吴420区的长8油层的扩边勘探也有了新的进展,储量大幅度增加,展现了靖吴地区良好的勘探前景。通过对长7以下油藏的物源方向、沉积微相及成藏富集规律等方面分析该区的勘探增储潜力,为下一步规模建产提供依据。The new understanding of Triassic geological conditions in Jingwu area promoted the exploration of under Chang7.G44 well,X82 well and L140-12well etc.oil point have been found,and high-yield industrial oil flows are obtained.Meanwhile,expanded boundary has been new progress in the exploration in Wu420 area,the reserves has a significant increase,which demonstrated a good exploration prospect.In this paper,favorable exploration areas of under Chagn7 are predicted by analysis the source direction, sedimentary microfacies,the law of accumulation and enrichment,which can provide basis for the next productivity construction.
