摘要
本文从实验室测定分析,地震资料处理、地下储集层非均匀性以及勘探实践为依据,对近几年在我国兴起的利用地震资料直接找油,如神经网络、多参数分析、分形分维等方法直接找油提出质疑;指出在我国陆相盆地中利用地震资料对气层可检测而对油层尚不能检测,更不能求含油饱和度,并客观地论述了这些方法的作用。
This article raises query to the prevalent direct hydrocarbon detection method in recent years by use of seismic data (such as neutral network, multiple parameters analysis and fractal dimensions) and points out gas reservoir can be detected directly by use of seismic data in continental basin in China, but oil reservoir, in particular, the oil saturation, can not be directly detected. Author demonstrated his idea through laboratory analysis, seismic data processing, subsurface reservoir heterogeneity and the previous exploration experience. However, author elaborates also the function of these techniques objectively.
