摘要
Based on structure oil-controlling theory, a series of band ratios (such as 5/1, 7/5, 7/3, (7-5)/(7+5)) is compared. Through the integrated interpretation and combined with geological structure information and geological data, 7, 5, 7 /3 is found to be the best band combination. With this combination method, the extracting of oil and gas halo information in Yakela region of Xinjiang produces satisfactory result, which proves its potential usage in other regions.
