摘要:
为解决老油田测井系列繁多、测井时间跨度长等复杂情况下常规的标准化方法难以取得理想效果的问题,提出一种综合的测井曲线标准化方法。统计各井标准层某条曲线的幅度值和平均值并插值得到其平面分布图;删除平面图上异常数据点后再重新插值,直到得到较光滑、无明显异常的平面图并将其作为趋势面确定各井曲线幅度和平均值的偏移量。利用该方法对某油田自1960年后完钻的1 700余口井进行了曲线标准化处理,结果表明,标准化后的测井曲线真实的反映了储层特征的平面分布规律、变化趋势和非均质性,避免了常规方法导致的人为把各井标准层特征值校正到同一定值上而忽视了地下储层固有的非均质性这一事实,也避免了直接利用趋势面方法造成的异常井直接参与拟合导致局部区域井曲线整体偏大或偏小的弊端。该方法综合了直方图统计分析和趋势面分析方法,结果更符合地质实际,对老油田储层测井解释中的曲线标准化处理具e 应用推广价值。
Abstract:
This paper presents a comprehensive method to deal with logging data which are diverse or may be recorded before a long time and under complicated conditions. Such data may be unsatisfactory if processed by conventional methods. First collect the amplitude and average values of the logging curve of the standard layer in a well, and then interpolate to obtain a plane distribution map. Second, delete the abnormal data points on the plane map and interpolate repeatedly until getting a smoother plane without obvious abnormality. Finally, determine the offset of the amplitude and average values using the smoother plane as a trend surface. This method has been used to normalize the logging curves from more than 1 700 wells drilled since 1960. Results show that the normalized logging curves can truly reflect the planar distribution law of reservoir properties, and reservoir variation and heterogeneity. This method eliminates the problem that a conventional method corrects characteristic logging data of the standard layer in a well to the same value and ignores the heterogeneity of underground reservoir, and avoids the malpractice that abnormal wells directly participate in fitting by using a trend surface, which leads to larger or smaller logging curves locally. Combining histogram with trend surface analysis, this method provides results more consistent with actual geological conditions. It is applicable for normalizing logging curves of old oilfields.
