摘　　要：室内流动实验模拟地层压力的变化情况是当前用来评价渗透率应力敏感性的重要方法之一。但是室内实验基值渗透率的选取、实验流体的选择等实验条件与实际地层情况差别较大,本文通过设计室内比对实验,全面分析室内实验条件影响因素,为需要应力敏感性实验的项目合理地进一步细化实验条件提供了具体的参数依据,为现场开发人员应用室内实验数据提供参考。The variation of formation pressure in indoor flow experiments is used to evaluate the sensitivity of permeability stress. However,the selection of base permeability and flow for experiments are quite different from those of field formations. The comparative test is designed in this paper to analyze the influential factors of the laboratory test and provide the specific parameters for site developers when they need to specify the experimental conditions of stress sensibility.
