摘要:

山前带包括前陆褶皱冲断带和前陆盆地靠近造山带部分,其油气资源极为丰富。根据前陆盆地的形成机制分类,将山前带划分为弧后前陆型山前带、周缘前陆型山前带和再生前陆型山前带。参考叠合盆地的分类方案,将山前带划分成正反转山前带和继承前陆型山前带。再生前陆型山前带和继承前陆型山前带仅在中国中西部地区发育。山前带的油气成藏具有一定的规律性,前前陆期沉积的页岩作为优质的烃源岩,前陆期砂岩和前前陆期碳酸盐岩是油气成藏良好的储集层,而泥岩、膏盐层、盐岩层等是优质的盖层,断层是油气运移的主要通道。前陆褶皱冲断带以构造圈闭为主,前陆盆地则以构造一地层圈闭为主。

Abstract:

The piedmont zone includes fold-thrust belt and foreland basin adjacent to the orogen. According to the formation mechanism classification of foreland basin,piedmont zones can be divided into three types,i. e. retro-arc foreland piedmont zone,peripheral foreland piedmont zone and rejuvenated foreland piedmont zone. Based on the superimposed basin classification,piedmontzones can be divided into positive inversion piedmont zone and successor foreland piedmont zone. Rejuvenated foreland piedmont zone and successor foreland piedmont zone are only found in the middle and western China. Some principles of hydrocarbon accumulation in piedmont zone have been summarized. Pre-foreland shale is source rock,foreland sandstone and pre-foreland carbonate rock are good reservoirs,and mudstone,gypsum salt and salt rock are cap rocks. Fault is the main channel of hydrocarbon migration. Structural trap is the main type in the fold-thrust belt,while structural-stratigraphic trap is dominated in the foreland basin.

Key words: piedmont zone, structural deformation, hydrocarbon accumulation, western Canada piedmont zone
