辽河滩海仙鹤地区东三段水下分流河道沉积体的地震多参数识别
|
摘要
地震、测井、录井及岩心资料综合分析结果表明,辽河滩海仙鹤地区东三段发育三角洲水下分流河道沉积,在岩心资料上为砂砾岩或含砾砂岩,在测井曲线上为高幅值钟形曲线,在地震剖面上为强振幅透镜状反射。利用三维地震资料,采用相干体处理技术和种子点雕刻技术揭示了辽河滩海仙鹤地区东三段三角洲水下分流河道沉积体的空间分布,水下分流河道沉积体呈条带状分布于HN8井—XH4井一线,L300测线以西分流河道砂体呈近S—N向,L300测线以东转变为SW—NE向。
It is proved from the data of seismic,well logging and core data that the deposit of deltic subwater distributary channel developed in East 3 member of Dongying Formation in Xianhe area of Liaohe shore,which is made of sandy conglomerates or gravel-bearing sandstones according to the core data,showing high value clock-shaped curve in the well logging and high amplitude lens-shaped reflection in the seismic section.Based on the 3D seismic data,the coherence cub technique and seed-pot engraved technique are applied to reveal the space distribution of deltic subwater distributary channel in the third member of the Dongying formation in Xianhe area of Liaohe shore.The deltic subwater distributary channel distributes on the belt along the line from HN8 Well to XH4 Well,in the direction of S-N on the west of the seismic line L300,but in the direction of SW-NE on the east of the line L300.
