摘　　要：生产井不稳定试井常常由于关井压力恢复时间的不足,影响了解释模型的选取,解释结果存在多解性。施工时,保持前、后期多次下入压力计的深度不变,录入缺失压力数据期间的产量历史,消除由于时间叠加而引起压力恢复导数曲线后期上翘的问题;进行试井分析时,利用压力与产量反褶积,准确地诊断和选取合理的解释模型。对封闭油藏特征的生产井不稳定试井,该方法具有一定的借鉴意义。The selected interpretation model is influenced for transient well testing to production well often due to the lack of recovery time at builtup pressure which results in multiple solutions of the explain results. When operation,keeping depth of the gauge lowered many times at former and later time to be constant,acquiring production history during lack of pressure data,eliminating the problem pressure derivative curves is upturned at late time caused by time uper position. When test analysis,by use of pressure and yield deconvolution,reasonable interpretation model is accurately diagnosed and chosen. By examples,it is shows that,to applying transient testing to closed reservoir,this analysis steps and methods is very practical,which has a reference sense to transient testing for the other reservoir characteristics.
