APPLICATION OF INTEGRATIVE GEOPHYSICS IN THE THREE-DIMENSIONAL GEOLOGICAL SURVEY IN THE PERIPHERY OF SONGLIAO BASIN

In the 3D deep geological survey in the periphery of Songliao Basin, the magnetic, gravity, magnetotelluric and seismic methods are employed to explore the Jarud Basin with igneous cover. With integration of geological and drilling data and physical properties of rocks, the subsurface geology is inferred comprehensively. The density, magnetic and electrical features are studied for the Permian Linxi Formation, which is the target formation of hydrocarbon resources survey. The surfing interfaces and distributions of the formation are characterized half-quantitatively or quantitatively, which provides essential fundamental data for the evaluation of hydrocarbon resources.
