摘　　要：运用现实生产中双频道回声探测仪探测动液面的原理和工作方法，在获取动液面深度的同时，根据油管漏失形成的死油环在测试曲线上出现特殊波的现象，解决了判断抽油井井下油管漏失的难题。经过对70多井次的现场验证，证明该方法具有较高的准确性和可靠性。Using the theory and work method of DWS, while getting the producing fluid level, the special phenomenon which according the annular clean oil respond in the special wave test line. The difficult problem for diagnosing the tube leakage in pumping well was solved. After verified 70 wells in oil field,it demonstrated that the method presented in this paper has high accuracy and reliability.
