摘　　要：从岩石学特点、成岩作用、孔隙类型、结构特征以及储层非均质性的主要影响因素等方面,对陆9井区侏罗系头屯河组储层进行了研究。研究表明,工区储层非均质性明显受沉积微相的控制。极好储层和好储层比例极少,仅在部分地区零星分布,主要分布于东北部。头屯河组储层岩性剖面分布具有明显的规律性,总体上表现出下粗上细的正韵律。南北方向储集砂体的连通性较东西方向好,砂体连通型式以复合型为主。The lithology,diagenesis,pore types,pore structure and main controlling factors of the Toutunhe reservoir in Lu well 9 in Jurassic are investigated.It is indicated that the reservoir heterogeneity of the work area is obviously controlled by the sedimentary microfacies.The proportion of excellent and good reservoirs is very small.They are scattered and mainly distrubited in northeastern part.The lithologic character of Toutunhe reservoir has obvious rule in the section and overall displays a fining-upward rhythm.The connection of reservoir sand-bodies in the north-south direction is better than that in the east-west direction,and is dominated by the composite type.
