其主要步骤为：首先，手工把输入图像粗略地划分为三个区域：前景区域，背景区域和未知区域。
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。
