| 为深入评价松辽盆地滨北地区石炭-二叠系油气地质条件,利用岩芯、岩屑及扫描电镜资料分析储层岩石学特征以及盖层条件,通过对烃源岩进行分析测试,依据地化指标来分析烃源岩有机质丰度情况,结合前人资料对石炭-二叠系油气地质条件进行评价。研究表明:研究区石炭-二叠系储层主要可划分为三种类型,即裂缝型储层、风化壳型储层和蚀变溶蚀型致密储层；石炭-二叠上覆地层火石岭组、泉头组一段—四段、青山口组一段、青山口组二三段、姚家组一段可成为基底良好的盖层；滨北地区石炭二叠系发育暗色泥板岩、千枚岩等潜在的烃源岩,样品显示烃源岩类型较好,生烃强度约为2×108~19.3×108/km2。通过分析认为,研究区具备良好的油气地质条件,有些工区勘探潜力较大,如西部中央坳陷区长垣以东地区及东北地区的黑鱼泡凹陷、明水阶地等构造区块、东北隆起区的绥化坳陷区和东南隆起区的长春岭背斜带是松辽盆地滨北地区石炭-二叠系的油气远景区。 |

| In order to evaluate the Carboniferous-Permian oil and gas geological conditions in the Binbei area of the Songliao Basin, the rock core, cuttings and scanning electron microscope data are used to analyze the petrological characteristics and caprock conditions of the reservoir. The source rocks are analyzed and tested according to geochemical indicators. To analyze the abundance of organic matter in source rocks, and evaluate the petroleum geological conditions of the Carboniferous-Permian based on previous data. The research shows that the Carboniferous-Permian reservoirs in the study area can be divided into three types, namely fractured reservoirs, weathered crust reservoirs and altered-dissolved tight reservoirs. Carboniferous-Permian overlying formation, Huoshiling Formation 1st-4th member of Quantou Formation, 1st Member of Qingshankou Formation, 2nd and 3rd Member of Qingshankou Formation, and 1st Member of Yaojia Formation can be good basement caprocks; the Carboniferous Permian in Binbei area develops dark mud slate and phyllite. The sample shows that the source rock is of a good type, and the hydrocarbon generation intensity is about 2×108~19.3×108/km2. Through analysis, it is believed that the study area has good oil and gas geological conditions, and some areas have great exploration potential, such as the Heiyupao Sag, Mingshui Terrace and other structural blocks in the western central depression area east of Chang Placanticline and the northeast area, and the northeast uplift area The Suihua depression area and the Changchunling anticline zone in the southeast uplift area are the Carboniferous-Permian oil and gas prospects in the Binbei area of the Songliao Basin. |
