少井条件下测井曲线标准化——以西江油田L区块为例

The Standardization of Well Logging Curve Under the Circumstances of Lacking Wells——A Case Study of L Block in Xijiang Oilfield

由于不同年代、不同仪器、不同刻度及人工操作方法的不同,使得测井曲线存在误差,这些误差的存在必然对测井综合解释的结果带来影响。为了消除影响,必须对测井曲线进行标准化处理。以少井条件下的西江油田L区块为例,采用直方图法对全区测井数据进行标准化处理。研究表明:利用直方图法进行本区的标准化效果较好。

Errors exist usually in well logging curve,as was caused by the difference of ages,instruments,scales and the method of manual operations. The existence of these errors will bring about great influences to the comprehensive logging interpretation. In order to eliminate the influences,a standardized disposal must be used in well logging curve. This article sets L block in Xijiang oilfield under the circumstances of lacking wells as an example. Histogram method is applied to some standardized dispose logging data in full area. The result shows that the effect of histogram is well for the standardization of the area.
