Abstract: From the view of data processing and information extraction, software has been designed and realized based on IDL according to the hydrocarbon micro-leakage theory. The software provides the data preprocess functions, such as band elimination, bad line repair, stripe elimination. And it also has the ability to analyze the pixel features and abnormal mineral information mapping with different methods, i.e. SAM, SCM, and SID. The capability of data process of the software can be the GB level, which is an important reference during the engineering use.
