摘　　要：试井测试时关井时间不足 ;试井解释时 ,基础参数选用不合理 ,模型诊断不合理 ,是造成新民油田试井解释地层压力偏低的主要原因。指出了在现场测试时应采取井下关井 ,使井筒储集系数减小 ,在有效的时间内提前出现径向流 ;在试井解释中应选用合理的基础参数 ,正确进行模型诊断。并利用沉积微相 ,根据生产动态 ,结合地质状况对地层压力进行综合分析。The situations why the estimated formation pressure from buildup test may be lower than true formation pressure were discussed in this paper, and concluded that not enough long shut-in time, unreasonable interpretation model and incorrect basic parameters value use were the main reasons. Using downhole shut-in tools, the wellbore storage effect can be eliminated and the radial flow can emerge early. In addition, the integration of depositional system analysis, geology study and production history analysis can significantly avoid getting an error answer.
