摘　　要：克拉玛依油田九6区齐古组油藏为浅层特稠油油藏,初期采用蒸气吞吐开采,之后转为蒸气驱开采,目前处在蒸气驱后期阶段,开采效果变差。针对这一现状,利用生产动态分析及数值模拟方法研究了蒸汽驱的驱替特征,定量地分析了平面及纵向上的温度场变化及蒸汽波及状况,提出了蒸气驱后期开采应采取的对策。Qiguzu reservoir in Kejiuliu blocks is shallow superheavy oil reservoir,it is exploited by steam stimulation primary,later,it is exploited by steam flooding,it is in later stage of steem flooding at present,effect of development turn to be worse.In view of the present situation,displacement cherictristic of steam flooding is studied by the method of production dynamic analysis and numerical simulation,and the change of temperature field and steam involving condition in lateral and vertical are analyzed,the development counter-measure in later stage of steam flooding is presented in the paper.
