摘要
常规测井受仪器纵向分辨率的限制,测井曲线分辨率普遍较低,薄层段的测井响应显示不明显,往往不能反映薄储层的真实信息,进而影响了薄储层的正确评价。为了正确地评价和解释薄层,本文通过反褶积法和频率匹配法来提高曲线的分辨率,并分别给出了具体的算法。通过分析,经过高分辨率处理后的曲线在很多层段上横向幅度得到了提高,层厚为0.3m的薄层段效果尤其明显。
The conventional logging which restricted by longitudinal resolution of well-logging instrument, can result in the low resolution of logging curve plot and less obvious logging response to thin layer, without providing the true information about thin reservoir and influence the accurate assessment on it. In order to accurately evaluate and interpret thin reservoir, the article discusses two methods of deconvolution and frequency matching to increase the resolution of the curve plot and offer the concrete calculation method. By the analysis, the curves processed by high resolution processing have been improved within a horizontal range, especially obvious for the thin layer of 0.3m thick.
