摘要(Abstract)：
基于测井条件下的几何因子思想对某油田的薄层测井资料进行了密度校正处理,处理后的测井曲线基本消除了围岩对薄层测井曲线的影响。误差分析表明,校正后的密度测井曲线与原测井曲线相比降低了与岩心孔隙度的绝对误差和相对误差。在此基础上完成了软件的编制,该软件的实际应用表明该方法简单实用,并提高了准确率。
Based on geometric factor under the condition of well logging,density calibration is developed for thin-layer well log data in an oilfield,and results show that,well logging curve is not influenced by shoulder beds.Error analysis shows that calibrated density well logging curve,in contrast to the original logging curves,have declined absolute and relative error with core porosity.Thus,based on this,software is complied,and its application shows it is a simple and practical method and improves accuracy.
