摘　　要：由于深部资料的不足及其多解性，在研究导油气构造时，多元相关信息的正确应用至关重要。在计算机上运用多元真三维地质信息系统（ＭＴ３ＤＧＩＳ）是实现多元信息定量化综合分析，并得出正确结论的关键。在研究区内，运用该系统将遥感、航磁、伽玛能谱等多元相关数据进行统计分析、配准及地层三维实体可视化分析后发现：在３５００ｍ深以下，区内的两个北东向盆地受一北西向构造控制。该构造是一规模大、多期次活动的透水性构造，并判断其为导油气构造。此判断与地震测深的结果一致。该带上有一大气田，是其为导油气构造的又一佐证。该结论已被有关部门所采用。其应用效果充分说明ＭＴ３ＤＧＩＳ在地质深部信息研究中的重要意义。Due to deficiency and interpretative uncertainty of deep geological data, the correct application of associated multi factor information is especially important for the research of oil and gas conducted structures. The key to analyze multi factor information quantitatively and comprehensively to obtain correct conclusions is to apply multi factor true three dimensional geological information system(MT3DGIS) Using this system, we register and make correlation analysis between variables from remote sensing, aeromagnetic, and gamma ray spectrum data, and make 3D solid visualization of stratigraphic data. Through these analyses mentioned above, we find that under depth of 3 500 m, two NE extended basins were controlled by a NW extended structure. This structure was large scale deep permeable structure with multiphase tectonic activity. So, we suggest that this structure is a oil and gas conducted structure. This inference is coincident with deep seismic sounding. The occurrence of a large gas field above this structure also supports this. Our conclusion has been adapted by relevant institutions. The application effect of this system indicates importance of MT3DGIS in research of deep geological information.
