Abstract: The present invention relates to a method for detecting water breakthrough in a well production. According to the invention the model, of which the accuracy is known, will receive three of the four following parameters: inlet pressure, inlet temperature, outlet pressure, outlet temperature. The model comprises a three-phase flash model including heat of evaporation of water and partial pressure of water with or without dissolved components lowering the vapour pressure such as salt and/or alcohol. Based on the said three parameters the model computes the fourth parameter, whereupon the actual fourth parameter is measured and compared to the computed fourth parameter. If the deviation between the measured and the computed parameter is considerably larger than that which can be explained from the level of confidence of the selected model and uncertainty of measurement, it can be concluded that a water breakthrough has actually occurred.

Abstract translation: 本发明涉及一种用于在井生产中检测水穿透的方法。 根据本发明，已知精度的模型将接收四个以下参数中的三个：入口压力，入口温度，出口压力，出口温度。 该模型包括三相闪蒸模型，其包括水的蒸发热和具有或不具有降低蒸气压的溶解组分（例如盐和/或醇）的水的分压。 基于所述三个参数，模型计算第四参数，由此测量实际的第四参数并将其与计算的第四参数进行比较。 如果测量和计算参数之间的偏差远远大于可以从所选模型的置信度和测量的不确定性中解释的偏差，则可以得出结论，实际发生了水的穿透。
