Application of raster data-based spatial analysis in oil and gas migration

The prediction of the dominant migration pathways of oil and gas migration is a key issue. The article starts from the parametric comprehensive analysis of the controlling factors such as transport system, energy field, etc. Through the establishment of the quantitative relationship between the various parameters and the dominant migration pathways, we use spatial analysis methods after the conversion into raster data so that the prediction and simulation of oil and gas migration paths can be realized. First, we achieve DTM data of the factors which are related to permeability of sandstone and fault and frame translocation with the methods like special difference; second, referring to DEM-based hydrological analysis, we set up the matrix of oil and gas migration direction based on various DTM data, and finally extract oil and gas migration path.
