摘要
为降低不同系列测井曲线的系统误差,提高储集层评价结果的可靠性,运用频率直方图法、趋势面分析法、频率直方图法与趋势面分析法相结合(结合法)的测井曲线标准化方法对扶余油田Z区块测井曲线进行标准化处理,并通过测井解释进行验证。结果表明,结合法所得深侧向电阻率校正系数为1.012;解释出的渗透率与岩芯分析的渗透率相关性更好;校正后的数据点明显集中,靠近趋势线。频率直方图法与趋势面分析法相结合的方法(结合法)更适用于研究区。
This paper comes up with a standardized well-logging curve method designed for reducing systematic errors in different series of logging curve and improving the reliability of reservoir evaluation. This standardized method,a combination of frequency histograms,trend surface analysis,frequency histograms and trend surface analysis,works better for standardizing Fuyu Z block logging curve,followed by the verification of logging interpretation. The results show that the combined method gives deep lateral resistivity correction factor of 1. 012; it gives permeability which correlates better with that by core analysis; it allows the corrected data points to be obviously focused,closer to the trend line. The combination of frequency histograms and trend surface analysis（ combined method） may work better for the study area.
