地震地层及地震相分析在川东南复杂储层识别中的应用

地震地层学及地震相分析目前还停留在简单的地震地层划分和以振幅、频率、连续性等地震波形特征划分沉积相方法上.作者以地震层序划分为基础,提出了研究有利储集体的地震相特征新方法,并在平面组合上与沉积相进行对比,可以更为精细地研究沉积相的空间展布规律,同时还可以指导储层预测研究.该方法对于那些勘探程度不高的地区尤为重要.

Application of seismic sequence and seismic facies analysis technique in complicated reservoir identification in the southeast of Sichuan, China

Seismic sequence and seismic facies analysis technique has been still based on the simple seismic stratigraphic classification and the seismic wave characteristic parameters, such as amplitude, frequency, continuity and so on, have been used to study the sedimentary facies in this method. By the seismic stratigraphic classification, the new way to study favourable reservoir using the seismic data is pul forward, and combined with sedimentary facies research, the precise study of sedimentary facies distribution becomes possible by using this technique, besides that, it can guide the reservoir prediction research. It is very important to use this way for exploration in the relatively lowdegree exploration areas.
