摘要
近年来,在国外一些油田和室内实验中,示踪剂(放射性及化学示踪剂)已得到较多的应用和发展,但在国内尚属罕见,本文根据作者的实践及研究,探讨了在岩心测试实验中,如何运用示踪剂数据确定岩心的均质程度、岩心中所合流体的饱和度及弥散度等问题。根据示踪剂浓度数据所确定的岩心中流体饱和度与物质平衡法所得流体泡和度相对照,结合相对渗透率曲线,可以确定出岩心中两种流体对岩石的润湿程度——即润湿相与非润湿相。上述这些性质和参数,对于进行岩心驱替实验,为油田开发提供科学论据,都是十分重要的。
Recently tracers (radioactive and chemical) have been relatively commo- nly used and developed in both laboratories and oil fields in foreign countries. In this paper it has been discussed how to use tracer in the determina- tion of homogeneity,fluid saturations of the core and its dispersion.Compa- rison saturations determined by material balance technique and tracer data, combined with the relative permeability curve,wettabilities of the core can be determined.All of these informations are very important for oil field deve- lopment and exploration.
