五二区克下组测井资料标准化方法研究

The Study Of Measures Of Well-data Standardization In The Set Of Ke Xia Of Wu Er Area

五二区油藏的测井资料的采集由多种系列的测井仪器完成,不同仪器所采集的资料存在一定的系统偏差。为了使测井资料具有统一的评价标准,测井数据能够真实地反映地层信息,就必须对测井曲线进行标准化处理。文中介绍了用于五二区克下组标准化处理的两种方法—直方图法和趋势面分析法,并对两种方法进行了分析对比,得出直方图法优于趋势面分析法的结论。

To an oil--field, in the process of exploration and exploitation, it is difficult to guaranty all well--logging curves getting in the same well instrument or using the same type standard machine and united method proceedings measures, so each well logging data may have an inevitable error which may firstly form the factor of degree difference. Therefore ,we must have to be undergone the standardization for to get the right dates of the well logging, it makes all the same kinds well data of have unify engrave, in other words ,to increase to measure the ability that well information solve problem within the scope of whole oil--field. With the living example, this thesis normalize the well data of the different layer in the choosed key wells and not--key wells through the correct methods of standardization, obtaining the finally correction value of each well, interpreting and evaluating the data of each well, last ,optimizing the best normalization method.
