摘要： The invention relates to method and apparatus for determining the flow rate of fluid in a well over an interval including zones where fluid is exchanged between the well and the formations through which it is bored.A logging sonde is used to measure the temperature of the fluid along said interval, and the flow rate is measured at least at the ends of the interval. Then for each depth, a flow rate value is determined from the measured temperatures and flow rates, and the set of values obtained in this way are recorded.
