摘要
根据滨南-利津地区浊积岩的发育位置、距离物源远近及流动状态的不同,开展了浊积岩类型划分,建立了浊积岩沉积模式,并利用五维地震数据预测了浊积岩有利发育区。研究结果表明:研究区发育陡坡近源构造坡折型、陡坡远源浊流型、陡坡远源碎屑流型和缓坡远源浊流型4种不同沉积模式的浊积岩,且其岩性、测井相、地震反射特征及发育位置均存在不同。顺物源方向进行地震数据叠加可以更好地描述浊积岩沿长轴方向的展布范围,垂直物源方向可以描述浊积岩短轴方向的边界。不同方位叠加数据体的叠合属性和乘积属性均能反映浊积岩的最大范围;而差值属性能够更清晰反映浊积岩的边界。
The sedimentary types of turbidite in the Binnan-Lijin area are diverse,making it difficult to predict effective reservoirs.Based on the development location,distance from the source and different flow states of turbidite,the types and sedimentary models of turbidite in the study area were summarized,and the favorable development areas of turbidite were predicted by 5D seismic data.The results indicate that there are four different sedimentary models of turbidite in study area:steep slope-near source-structural slope break type,steep slope-far source-turbidity current type,steep slope-far source-debris flow type and gentle slope-far source-turbidity current type,and there are differences in lithology,logging facies,seismic reflection characteristics and development location.Stacking seismic data along source direction can describe the distribution range of turbidite along the long axis,and stacking data vertically can describe the boundaries of turbidite along the short axis.The sum and product attributes of seismic data stacked in different azimuth can reflect the maximum range of turbidit,and the difference attribute can more clearly reflect the turbidite boundary.
