摘　　要：不考虑测试管柱规格、流体密度等敏感参数 ,采用体积与流动压力的均一化处理 ,用数学方法计算段塞流产量 ,减少了误差因素。用数理统计的方法回归压力与时间的函数关系 ,大大减少了压力卡片数字化时产生的随机误差 ,同时也减少了由于机械压力计本身精度引起的系统误差。应用此方法计算的产量真实反映了地层流体的动态流动特征 ,更为客观。No considering the sensitive parameters of testing stems and fluid density,the uniform process of volume and flow pressure is used and that with mathematical method to calculate plug flow rate can reduce error factor.Random errors decreased greatly produced during the process of digital formatting to card with statistic method to regress function relationship of p&t,meanwhile,the systemic errors can also reduced caused by mechanic gauges' accuracy.By use of it can really reflect dynamic flow features of formation fluid.
