摘　　要：为解决低渗透气藏测井解释渗透率误差较大的问题,以十屋断陷西部凹陷区A断块气田为研究对象,在相控建模的基础上,结合低渗透气藏的特点,对储层渗透率进行动态校正,并以符合低渗透气藏特点的动态分析结果对模型进行约束。结果表明,将动态资料与静态资料结合共同约束建立地质模型的方法更符合地质及开发的实际,地质模型的精度得以提高,模型历史拟合率可达到53.8%。This paper seeks to address the larger permeability errors associated with logging interpretation of low-permeability gas reservoir,as is the case of fault block gas field A in western sag of Shiwu fault depression.The paper does this by performing the dynamic correction of reservoir permeability by applying facies control modeling and combined with the characteristics of low-permeability gas reservoir;and constraining the model using the dynamic analysis results conforming to the characteristics of low-permeability gas reservoir.The results show that the method featuring the use of joint restraint-combining dynamic data with static data for the development of geological models,lends itself better to the reality of geology and development;enabling the improved accuracy of geological model and thus the success rate of 53.8%for one-time historical fitting of the model.
