摘　　要：由于深层凝析气藏特殊的储层物性及流体流动规律,采用常规的压力恢复测试获取地层参数和井控范围受到较大限制,无法准确确定单井控制区域储层物性和可动储量。在阐述Blasingame产量递减分析理论的基础上,针对某变质岩凝析气井开展分析,基于图版拟合结果得到了该井控制区域储层渗透率、井控半径及动态储量等关键参数,为气井生产动态调整提供了基础支撑。Due to the unique reservoir properties andfluidflow patterns of deep condensate gas reservoirs,it is difficult to use the conventional pressure testing obtaining formation parameters and well control ranges,which makes it difficult to accurately determine the physical properties and movable reserves of a single well control area.On the basis of Blasingame production decline analysis,this article conducts analysis on a metamorphic rock condensate gas well.Based on thefitting results of the chart,key parameters such as reservoir permeability,well control radius,and dynamic reserves in the control area of the well are obtained,which provides basic support for the dynamic adjustment of gas well production.
