Abstract:
Xuzhou-Huaibei-Huainan region is one of the major coal industry bases in China.Around it are Mesozoic-Cenozoic overlaping basins of Zhoukou,Huangkou,Hefei,etc.,which are the major prospective areas for explorating the natural gas formed by the metamorphism of coal-bearing formation.The Carboniferous-Permian coal seams within this region are about 5-30m in thickness,with sufficient gas source.In the step-faulted zone in the east of Zhoukou basin and the deep-seated areas in both east and west ends of Huainan syclinorium,the source rocks of gas is well developed.During its deep-buried process the regenerated gas was also formed.Additionally there exist anticline structure and other types of trap,so this region is the main accumulation area of coal formed gas,a major prospective area for exploration.Deep segs in the central basin are places to search for overpressured gas.
