遥感信息量化处理在西昌地区构造解析及油气远景预测中的应用

该文从地质遥感信息定量分析着手、通过对遥感图像进行处理和信息提取, 新发现大量重要地质构造信息。并按不同构造层次对线性、环形构造等信息进行了量化处理, 进一步建立了研究区区域构造和重要构造区带遥感信息三维彩色量化解析模式。通过区域断裂系统量化解析, 确定了相对稳定的含油气构造地块和重要的构造区带; 通过重要构造区带遥感解译的环形构造及与其有成因联系的环状、放射状大节理的量化处理和定量解析, 确定了含油气局部构造。最后通过局部构造综合评价研究, 预测了含油气远景区。

APPLICATIONS OF QUANTITATIVE PROCESSlNGS OF REMOTE SENSING INFORMATION TO ANALYSIS OF STRUCTURES AND PREDICTION OF PROMISING AREAS IN XICHANG REGION, SICHUAN

Abstract In this paper, with the quantitative analysis of remote sensing information, the image processing and the feature extract were done. Many important geological and structural information were discovered. According to different scale and original, the information of linear and circular structures are seprarately processed, 3-dimension patterns of remote sensing information were established for the regional and the important structure areas. Through a quantitative analysis of regional fault system, the relatively static structure masses were determinod. And through a, quantitative processing of the information of the circular structures and the joints related to the circular structures in the important structure area, some local structures bearing oil/gas were detemined. Finally,with a synthetic analysis and assessment for local structures, promising areas bearing oil/gas were predicted.
