【摘要】 随着地震属性提取方法的不断完善,地震属性分析已经大量应用于油气勘探的各个阶段,并取得了较好的应用效果。准噶尔盆地西北缘百56井区风城组发育了一套扇体,针对其特殊的地震响应特征,从地震相分析入手,在属性分析优化的基础上,优选出能够凸显扇体特征的敏感属性,进而对扇体的空间展布及扇体内部沉积亚相进行了识别和预测。更多还原

【Abstract】 With the development of seismic attribute extraction methods,seismic attribute analysis was widely used at every stage of the oil and gas exploration,and good effect was achieved in application.A set of fans were developed in Fengcheng Formation of Wellblock Bai 56 in the northwest margin of Junggar Basin,in allusion to the special seismic response of the fan,this paper starting from the seismic analysis and based on the seismic attribute optimization,the best and sensitive attribute is selected to predict the fan distribution and its sedimentary subfacies.更多还原
