提取数据
萃取数据

Method allows us to merge the data we obtained in a current extraction with an archive file of past extraction data
方法允许我们把在当前抽取中获得的数据合并到包含以前抽取数据的档案文件中。
The main steps are extracting and analyzing different types of attributes , preprocessing the extracted attributes , rejecting attribute anomalous values and filtering , seeking and selecting the sensitive attributes combined with drilling and oil extraction data , descending the optimal seismic attributes through k - l changes , and using the synthetic analysis technology with linearity and nonlinearity on reservoir prediction
其主要步骤为：不同种类的属性提取和分析；属性的预处理，即剔除异常值并进行滤波等处理；结合钻井、采油资料寻找和筛选敏感属性；利用k - l变换来对优选出的地震属性进行降维处理；利用线性、非线性等综合分析技术进行储层预测。
