摘要
Main folds of Lichuan-Cili corridor section,faults deformation formed in Yanshan-Himalayan age can be divided into five deformations.Source-reservoir-cap of Sinian-Lower Paleozoic in the region is in good condition,and the formation of multiple sets containing hydrocarbon accumulation assemblages,has formed a certain scale of industrial gas reservoirs in the favorable geological conditions.It is significantly better than the Upper Paleozoic-Triassic systems.Combination of source,reserve,cap and movement,circle,construction conditions,the authors forecast Shimen-Sangzhi synclinorium and Huaguoping synclinorium are favorable zones of oil and gas exploration.
