【摘要】 利用地震相、测井相、地质录井和岩心分析资料,分析海拉尔盆地下白垩统扇三角洲的宏观发育模式和沉积特征.结果表明:海拉尔盆地扇三角洲主要发育单一断层控制型和多级断层调节型2种沉积模式;认为储层含油性与沉积微相有密切关系,扇三角洲前缘的水下分流河道微相和扇三角洲前缘的河口坝微相是2种主要的含油微相;沉积水动力是影响储层非均质性的主要原因,水下分流河道微相中部的槽状交错层理砂岩相和河口坝微相顶端的交错层理砂岩相储层物性和含油性最好.更多还原

【Abstract】 On the basis of seismic data,well logging and core analysis data,the macroscopic development model and sediment characteristic of fan delta in Hailaer basin are analyzed,the type of only one fault controlling and the type of multilevel fault adjustment are the two key types,the underwater distributary channel and mouth bar in the deltafront subfacie is dynamical reserves of hydrocarbon.Because of the sediment hydrodynamic force,the physical property of festoon cross-bedding sandstone face in the middle of underwater distributary channel and the cross-bedding sandstone face in the up of mouth bar is good.更多还原
