摘要
以岩石组合特征、同位素测年及孢粉化石组合特征为依据,参考区域地层发育状况,对高力板断陷高D1井钻遇地层进行划分对比。结果表明:高D1井钻遇地层自下而上划分为晚二叠世林西组(2.911 5~2.749 0km)、早三叠世老龙头组(2.749 0~2.461 0km)、中侏罗世万宝组(2.461 0~2.191 0km)、晚侏罗世—早白垩世满克头鄂博组(2.191 0~1.206 0km)、早白垩世玛尼吐组(1.206 0km~330.0m)、早白垩世白音高老组(330.0~198.0m),以及第四系松散砂砾层(198.0~0m)。发育晚二叠世林西组和中侏罗世万宝组两套重要的生烃层系,为松辽盆地侏罗系及二叠系油气资源潜力调查与评价提供支撑。
Based on the characteristics of rock assemblage,isotopic dating and palynology assemblage,and the stratigraphical series of the regional geological,dividing and comparing the strata founded from the GD1 well in the Gaoliban Fault Depression,the results indicate that the layer of the well depth 2.911 5~ 2.749 0 km in borehole GD1 belongs to the Late Permian Linxi Formation,2.749 0~ 2.461 0 km belongs to the Early Triassic Laolongtou Formation,2.461 0~2.191 0 km belongs to the Middle Jurassic Wanbao Formation,2.191 0~1.206 0 km belongs to the Late Jurassic-Early Cretaceous Manketouebo Formation,1.206 0 km^330.0 m belongs to the Early Cretaceous Manitu Formation,330.0~198.0 m belongs to the Early Cretaceous Baiyingaolao Formation,and 198.0~0 m is the sand and gravel of the quaternary.Two important hydrocarbon-generating strata,Late Permian Linxi Formation and Middle Jurassic Wanbao Formation,have been founded in the study area.The research results provide support for the investigation and evaluation of the hydrocarbon potential of Jurassic and Permian in Songliao Basin.
