摘要
吐哈盆地火焰山断裂带夹持于西部弧形带和生烃凹陷胜北次凹之间,油气怎样由胜北次凹向西运移值得研究。对火焰山断裂带演化历史和西部弧形带成藏期进行了分析,认为火焰山断裂带在早、中侏罗世表现为沿煤层滑脱的正断层,在侏罗纪末期发生轻微反转,强烈逆冲并定型于第四纪,油气藏形成主要有两期:白垩纪末期-早第三纪和早第三纪末-第四纪早期,油气的充注发生在火焰山断裂带形成之前。火焰山断裂对第四纪以前的油气运移并没有影响,但终止了第四纪以来油气向西运移,决定了油气藏以煤系油为主、规模小的特征。
The formation of Burning Mountain was between western arc-like zone and Shenbei Sub-sag. It was necessary to study how did hydrocarbon migrate from Shenbei Sub-sag to western arc-like zone. Based on the analyses of evolution of the formation of Burning Mountain and forming time of oil-gas pools in the zone, the formation of Burning Mountain was a normal fault slipping along coal formation in early-middle Jurassic, and reversed slightly in late Jurassic, and thrust was strongly formed in Alluvium period. The time of hydrocarbon accumulation consists of two stages: the late period of Cretaceous system to early Tertiary period and late period of early Tertiary to nonage Quaternary Period. The infusion of oil-gas happened before the forming of the formation of Burning Mountain. The formation of Burning Mountain had no effect on the migration of oil and gas at the first stage, but it stops migration of oil and gas at the second stage.
