Application of Multi factor True Three dimensional Geological Information System to Research of Oil and Gas conducted Structures

Abstract

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.
