摘要： A device and method for determining the flow of steam in a production well has a sonde with a pair of gamma ray detectors and a source of gaseous radioactive material therein. The sonde is lowered into the well and measured amounts of the gas are released and detected by the gamma detectors to thereby determine the volume and velocity of steam flowing in the production well as well as its depth of entry.
