摘要
分辨率匹配法提高测井曲线纵向分辨率是通过滤波及线性拟合把低分辨率测井曲线的分辨率提高到与另一高分辨率测井曲线相同的分辨率，进而达到识别薄层信息的目的。通过非线性拟合的尝试，对电阻率曲线的线性与非线性拟合进行比较，分析了两种拟合的效果差异，得出非线性拟合在提高测井曲线纵向分辨率具有更好的效果。
Resolution matching method can improve vertical resolution by filtering well logs and linear fit to make the resolution of a lower resolution well log same as another high resolution one in order to identify thin-layer information.Attempts by non-linear fitting of resistivity curves of linear and nonlinear fitting comparison,analysis of the effects of two different fitting,it is discovered that nonlinear regression makes better results on the improvement of vertical resolution of well logs.
