摘要

It has been proved by practice of exploration that the Carboniferous System in the Junggar Basin is a set of prospective strata of actual exploring. The carboniferous volcanic rock has a large scale and a wide distribution in the Ludong-Wucaiwan area, and is an important reservoir rock of gas. The upper segment and the lower segment which are volcanic rocks show the discontinuous mounded reflection or chaotic refection, but the middle segment which is sedimentary rock displays stronger amplitude and more continuous parallel and sub-parallel reflection. Most of the sub-facies which are far away from volcanic vents develop on the east and west sides of sub-facies after the volcano explode. Effluence facies mainly distribute in South-North major faults. The weathering crust reservoirs which are coupled with nearby structures, lithology and lithofacies, are the best to form the oil/gas reservoir, which form the stratigraphy-lithology origin volcanic rock gas reservoirs in the tectonic settings.
