摘　　要：四川盆地侏罗系陆相页岩油气已在复兴、普光、平昌等地区取得勘探重要发现,展现出巨大的勘探潜力。基于钻井、测井、地震、岩心观察以及实验室分析测试等资料,开展相关研究工作。结果表明,红星区块凉高山组页岩品质整体较好,油气可流动性较好,其中红星区块中南部地区生烃潜力略好于北部,且物性条件更优,是下步勘探评价重点地区。Significant exploration discoveries of the Jurassic Lianggaoshan Formation continental shale oil and gas have been made in the Fuxing,Puguang,and Pingchang areas of the Sichuan Basin,demonstrating great exploration potential.Through drilling,logging,seismic,core observation,and laboratory analysis and testing,a comprehensive evaluation of the geochemical characteristics,physical properties,and oil and gas content of the lower sub-member of the Lianggaoshan Formation in the Hongxing Block was conducted.The study identifies favorable exploration areas.Results indicate that the lower sub-member of the Lianggaoshan Formation in the Hongxing Block has good overall shale quality and oil and gas flow potential,with the southern and central areas having slightly better hydrocarbon generation potential and better physical conditions than the northern area.These findings provide important insights for shale oil and gas exploration and evaluation in the Lianggaoshan Formation of the Hongxing Block.
