摘要
陆梁油田油气主要分布于白垩系吐谷鲁群、侏罗系的西山窑组和头屯河组;储层岩性主要为中细砂岩,砂岩分选性好-中等,结构成熟度较低。白垩系吐谷鲁群和侏罗系储集岩的孔隙组合类型主要为粒间孔、粒间孔+高岭石晶间孔,少量粒内溶孔+高岭石晶间孔。影响储层储集性能的主要因素:(1)沉积环境,(2)古气候,(3)成岩作用,(4)构造运动,(5)粘土矿物。
The oil and gas distributed mainly in the Tugulu Group of Cretaceous and the Xishanyao Group and Toutunhe Group of Jurassic . The lithology of reservoir is chiefly mid-fine grained sandstone with good sorting and low texture maturity.Pore in the Tugulu Group of Cretaceous and Jurassic reservoir occurred mainly among between grains or as intercrystal pore of kaolinite grains with minor intragranular pore plus intercrystal pore of kaolinite.The factors affecting the property of reservoir were as follows.(1)environment of sedimentary, (2)paleoclimate, (3)diagenesis,(4)tectonic movement,(5)clay minerals.
