摘要
用地震资料进行沉积微相研究 ,需要深入研究并利用地震道与道之间反射时间和振幅的规则变化信息 ,这样可以较为有针对性地描述微相的变化。本文提出了以高分辨率地震剖面为基础资料划分油层组沉积微相的方法 ,通过在松辽盆地北部太康北地区的实际应用 ,收到了良好的效果。这种方法适用于沉积亚相为三角洲前缘的地区。
The study of sedimentary microfacies using seismic data requires regular variation information of reflection time and amplitude between seismic traces. Such information is useful to the description of the change of microfacies. This paper presents a method of differentiating sedimentary microfacies based on high resolution seismic sections. The method has been applied in the Taikangbei area, northern Songliao Basin, and brought good results. The method is suitable for the area where the sedimentary microfacies belongs to delta front.
