摘　　要：辽河油田稠油井,由于油管套管环空处存在"死油块"或"泡沫段"影响,获得液面测试结果误差很大。采用油套环空注氮气技术,结合质量守恒定律,以气体状态方程为基础,建立了环空注气油井液面测试数学模型及试验装置。通过测试油井环空注气量、压力及温度的变化情况来求解油井的液面。现场试验结果表明,液面测试误差由原来几十米甚至几百米降至19m。To heavy oil Wells in Liaohe oilfield,for influence of ' dead oil' or ' bubble' place at annulus between tubing and casing,test result error of the liquid level is very large. By using the oil casing annulus nitrogen injection technology,combined with the conservation of mass,on the basis of gas state equation,the annulus gas injection oil well liquid level test mathematical model and test apparatus is established. By testing the well annulus injection volume,pressure and temperature changes in the situation,oil well liquid level is solved. Field test results show that the liquid level test error from dozens or even hundreds of meters to 19 m.
