摘要
以四川盆地东北部某区上二叠统长兴组海相碳酸盐岩台地沉积为例,综合应用钻井和地震资料,在层序划分和等时层序界面追踪的基础上,通过拉平东吴运动面来创建地震拉平数据体,并沿长兴组顶界面提取地层切片,得到长兴组地震古地貌图,据此获得沉积相带的大致分布范围。在井震标定和地震相精细解释的基础上,通过地震相向沉积相转换,对礁滩体的展布以及研究区的沉积相平面分布做了精细刻画。结果表明,碳酸盐岩地震地貌学是恢复沉积体系的一种有效方法。
Based on the principle of sequence stratigraphy and seismic geomorphology, an analysis of seismic geomorphology is successfully applied in reconstructing the depositional system of the Upper Permian Changxing marine carbonate rock at some study area in the northeast part of Sichuan Basin. Base on regional geological information and synthetic seismogram, a seismic paleogeomorphic map is acquired by means of determining the time-equivalent sequence framework and surfaces, flattening layers and extracting the strata slices along the time-equivalent top boundaries of Changxing Formation. After transformation of seismic facies to depositional facies, the characterization of Changxing depositional plane distribution is depicted.
