摘　　要：通过动液面测试,可以了解油井的供液能力和井下设备的工作状况,为油井生产分析提供依据。目前,一些深井、高油气比油井的动液面测试结果不准确,原因是声波能量衰减快,现有测试枪存在不足。设计了气压组合型测试枪,声源为声弹、套管气、氮气。与常规方法测试曲线对比,氮气声源测试的液面反射波标准、清晰,易于定位,特别适用于高油气比油井的动液面测试。Well liquid supply and the working condition of down hole equipment through the oil well dynamic liquid level monitor to provide the basis for well production analyses. At present, the dynamic liquid level test results were inaccurate in some deep wells and the high gas liquid ratio oil wells. The reason was sound wave energy rapid damping and test gun deficiencies. A pressure combined type test gun was designed; the acoustic wave source has acoustoelastic, casing gas and nitrogen. Contrasted with conventional test method,the testing curve reflecting wave using nitro gen as wave source was standard,clear and easily located. It has the higher value,particularly applicable to high gas liquid ratio oil wells.
