摘　　要：通过吸汽剖面测试可以得到井下蒸汽干度分布和油层的吸汽情况,为注汽效果分析和注汽参数调整提供依据。由于数据分析的数学模型假设情况与实际注汽管线和井下管柱结构相差较大,导致理论模型计算的沿程干度值偏高,计算结果直接影响下一步调整措施,因此采用注汽系统热损失和井下蒸汽干度取样测试结果对模型进行校正,给出了校正后的计算方法。通过实例计算可以看出,实际的蒸汽干度沿程分布低于校正前的理论计算值,计算结果更加贴近实际。The steam dryness distribution and the steam absorption condition in reservoir can be obtained by testing the steam absorption profile, which provides the basis for the analysis of steam injection effect and the adjustment of steam injection parameters. There is a great difference between the hypotheses for data analysis mathematical model and the actual structure situation of steam injection pipeline and downhole string, which results in the steam dryness calculated by theoretical model is higher than actual steam dryness and therefore directly affects the next adjustment measures. The theoretical model for the calculation of steam dryness is corrected by the test results of the steam injection system heat loss and the sampling of downhole steam dryness, and the corrected calculation method is given. The case calculation results show that the corrected steam dryness distribution is lower than the calculated steam dryness distribution by the theoretical model, and it is more close to reality.
