中文摘要:
      根据地化指标及测井资料分析了准噶尔盆地西北缘克—乌断裂带断裂活动以及断裂带岩性(火山岩、碎屑岩)对油气分布的影响.认为断裂活动及断裂带岩石物性对油气分布具有明显控制作用,在断裂活动期间,断裂带为油气运移提供良好通道,成熟度较低的油气通过断裂带运移至上覆地层;断裂活动平静期,断裂带碎屑岩对油气起封闭作用,火山岩断裂带仍是油气运移通道.成熟度较高的油气经过火山岩运移到断裂带内缘聚集成藏,在断裂带外缘,由于碎屑岩封闭作用及成熟度较高油气的排替作用,油气成熟度呈现"上低下高"的分布格局.
英文摘要:
      Distribution of petroleum is apparently controlled by fault activities and rock's physical properties in fault belt. During the fault activities, petroleum with low maturation migrate along the fault belt into the pinch-out zone;During the quiet period of fault activities,the clastic rocks in fault belt sealed the petroleum,and the volcanic rocks is still the migration passage. Petroleum with high maturation migrate through volcanic rocks and accumulate in the inner part of fault belt. In the outer part, the maturation of petroleum decrease upward owing to the seal of clastic rocks and displacement of high-matured petroleum.
