摘要： 将赋予了新内涵的流场概念引入到油气二次运移研究中,对流场进行了系统分类和特征描述。并明确指出,流场是指流体所占据的空间,通常由储集层和输导层或运载层构成。由大到小可划分为盆地-区带规模流场、油田-油藏规模流场、层规模流场、孔隙规模流场4个级别。探讨了流场类型、规模、差异和汇集烃源岩区油气的能力对油气运移聚集、成藏规模、成藏位置的控制,并明确指出研究区准噶尔盆地西北缘三叠系克拉玛依组底部的不整合面流场是汇集、输送分布其上下烃源岩中油气的主要通道。

Abstract: A concept of flow field with new meanings is introduced into study of secondary petroleum migration, and systematically clas-sified and characterized. Flow field refers to the space occupied by fluid, comprising reservoir, transport layer or carrying layer. It is divided from large to small scale into basin-region flow field, oilfield -reservoir flow field, layer flow field and porous flow field. This paper discusses the flow field type, scale, difference and capacity for collecting hydrocarbon in source area and their ffcts on contolling petroleum migra-tion/ accumulation, reservoir scale and location. It is definitely pointed out that the unconformity flow field of bottom of Karamay formation in northwestern margin of Junggar basin is major pathway for accumulating, transporting and distributing hydrocarbon from source rocks up and down in study area.

Key words: Junggar basin, northwest, flow field, secondary migration, reservoir, unconformity, fault
