摘要
准噶尔盆地西北缘红车断阶带油气分布复杂 ,油气藏类型多 ,有稠油、正常油和轻质油 ,还有干气藏。稠油主要分布在断阶带上盘 ,正常油和轻质油分布在断阶带的下盘及断阶带之间。油气产层多 ,从石炭系到白垩系均发现油气。采用原油轻烃及天然气碳同位素判断该区油气源 ,指出油气来自昌吉凹陷二叠系风城组和乌尔禾组源岩 ,并指出各期油气的分布及次生改造特征。结合源岩生烃史与构造演化史 ,建立了成藏模式 。
The oil and gas reservoir types are very various in Hongthe faults of northwestern part of Zhungaer basin,including heavy oil,light oil and dry gas. The heavy oil is distributed at the handing wall, light oil and gas reservoir at the footwall. Reservoirs rang from Carbonniferous to Cretaceous. Oil and gas is sourced from Fengcheng formation and Wuerhe formation of Changji sag based on oil light hydrocarbon and natural gas carbon istope , oil and gas distribution character at different stage and the character of the secondary change are studied. Reservoir formation model is estalished, and favourable exploration area is also determined.
