摘　　要：石油和天然气均属于流体矿产物,其最重要的特征便是具有可流动性。当这些油气受到某种驱动力作用时,便可在地层中流动,这种流动被称为油气的运移[1]。本研究以鄂尔多斯盆地青化砭地区为例,对其油气运移的动力、通道进行深度分析,通过对剥蚀厚度恢复确定油气运移的方向[2]。结果表明,研究区长4+5及长6段的流体运移主要由南向北为主,长7油层组中的张家滩页岩是长4+5、长6油藏中的原油的主要来源。Both oil and natural gas are fluid minerals,the most important feature of which is fluidity.When these oil and gas are subjected to some driving force,they can flow in the formation,which is called oil and gas migration[1].This paper takes Qinghubian area of Ordos Basin as an example to conduct in-depth analysis on the driving force and channel of oil and gas migration,and determine the direction of oil and gas migration by restoring the denudation thickness[2].The results show that the fluid migration of Chang 4+5 and Chang 6 is mainly from south to north,and the Zhangjiatan shale in Chang 7 is the main source of oil in Chang 4+5 and Chang 6 reservoirs.
