An attempt to apply trend-analysis techniques to search for oil- and gas-bearing structures in orogenic regions (a case study of the Baisun basin)

Abstract

Morphostmctural analysis of the orogenic Baisun basin has been carried out using two levels of topographic generalization (by averaging over radii 3 and 6 km long) and differences between the two levels (6 minus 3 km). The resulting maps, supplemented with geological-geophysical materials and drilling data, elucidated pattern of local topographic anomalies (models) or morphostructures which are genetically related to under-salt structures, and to structures above and below overthrusts. About 10 morphostructures have been identified by corresponding gravity anomalies.
