摘要
中子测井是提供地层孔隙度和岩性信息的重要手段。在研究薄互层时,为了获得正确的储层参数,必须采用一些新的处理技术。J.E.Galford(1986年)以及 M.P.Smith(1990年)分别提出了两种提高中子测井纵向分辨率的处理方法,即 Alpha 方法和 DFSN 方法。本文针对这两种方法给出具体的算法,并结合我们具体的地质条件,对这些算法的效果作了分析和比较。
Neutron log is an important means for providing porosity and lithology information.For thin beds some new processing techniques must be taken to obtain correct reservoir parameters.J.E. Galford et al.(1986)and M.P.Smith(1990)proposed two methods to enhance vertical resolution of neutron log——Alpha method and DFSN technique respectively.The algorithms of these two methods are given in this paper and their effects are compared and analysed by applying them to specific geological conditions.
