【摘要】 松辽盆地北部太平川地区扶余油层单砂体具有薄、多、散、杂等特点。砂体厚度横向变化快,用常规的预测方法难以对单个砂体进行准确描述。为此,在该区展开了基于合成记录正演模型的河道识别技术的研究与应用。通过精细落实研究区内储层展布情况,利用合成记录正演模型技术,对扶余油层河道砂体识别展开研究工作。通过对已钻井岩石物理分析,利用Landmark合成地震记录对单井目的层进行去砂层实验,从而确定工区目的层的地震响应特征,针对正演模型得出的响应特征对主要目的层进行属性分选、优化,最终对松辽盆地北部太平川地区的扶余油层河道砂体进行识别,并采用三维可视化技术对河道进行空间刻画。更多还原

【Abstract】 Northern songliao basin TPC area of Fuyu oil layer of single sand body with thin,much,loose,miscellaneous characteristics,and the thickness of sand body changes quickly in one horizon.Using conventional reservoir prediction method is difficult to predict and descript accurately with single sand body.Therefore,in this region,a channel prediction technology research and application are launched which based on synthetic seismic records of forward modeling.Through careful research in reservoir distribution,use of synthetic seismic records forward modeling technology to launch the research of Fuyu oil reservoir channel sand body recognition.Through to the known drilling rock physics analysis,and using syntool of the Landmark,experiments are done repeatedly on remove some sand layers,so can determining seismic response of the area objective stratum characteristics.Aiming at attributions response characteristics of the model of major horizon,the best seismic attributes is selected,and used these seismic attributes to predict the channle sand of Fuyu reservoir.And by using three visualization technology is described the channle sand.更多还原
