基于双标准层趋势面分析的测井资料标准化方法
首发时间:2011-12-07
摘要:常用的测井资料标准化方法对单标准层进行分析,最后仅得到单一的乘因子或者加因子,导致标准化后得到的测井资料井间可对比性不好,储层参数建模的精度难以提高。考虑测井系列的一般线性刻度方法及其误差传播,本文尝试选取两个稳定分布的标准层。通过对该两个标准层采取趋势面校正处理,得到符合一般线性刻度方法的测井资料的线性校正公式。该方法在ST地区对48口井进行了测井资料标准化处理,校正效果得到明显改善。

TREND SURFACE ANALYSIS NORMALIZATION METHOD OF LOG DATA BASED ON trend surface analysis of DOUBLE KEY BEDS
Abstract:Log data normalization methods frequently-used are based on single key bed and get single additive or multiplicator, which make unfavorable uniformity of log data well-to-well after normalization and low precision of modeling to reservoir petrophysical parameters. Considering usual liner calibration of logs and the error spread pattern, this paper try to choose two key beds that distributes steadily. Dealing such two key beds with trend face method and get liner correct formulas which consistent with the liner calibrations. It normalized log data of 48 wells in ST area in this method and showed much improvement.
Keywords: Log data normalization trend surface analysis linear scale double key beds
