本方法是在常规的数字处理方法基础上发展的一种全新的评价油、水层方法。基于对砂泥岩地层油、水层规律的研究,在测井解释中首次提出采用含油饱和度、泥质含量(岩性系数)、孔隙度、径向侵入系数、原油性质等反映油水层规律的多个参数对油水层进行评价,并采用现代数学——判别分析方法对油层、油水同层、水层进行最优的归类判别,从而实现了用电子计算机自动评价油层、油水同层、水层、干层。成果图显示直观、清楚。
This method is a new method of evaluating oil and water layers developed on the basis of conventional digital processing methods. Based on the study of the law of oil and water layers in sandstone and mudstone formation, it is the first time to interpret the law of oil and gas in the interpretation of oil and water by using oil saturation, shale content (lithology coefficient), porosity, radial invasion coefficient and crude oil properties Multiple parameters to evaluate the oil-water layer, and using modern mathematical-discriminant analysis method to classify the oil layer, oil-water layer and water layer optimally, so as to realize the automatic evaluation of oil layer, oil-water layer, water layer Layer, dry layer. The diagram shows intuitive and clear.
