摘　　要：溢气型同轴线相位找水仪通过气液分离的方式,在一定程度上实现了将油水气三相流转换为油水两相流状态下的测量,从而减小气相对液相流量和含水率测量的影响,提高了产层特性判断的准确性。通过在海拉尔油田贝301区块的现场试验与对比分析,对于低产液油井,溢气型同轴线相位找水仪测量结果能够提高流量和含水率的测量精度,并实现产气量估算分析。另外,总结分析了仪器含水率计测量的主要影响因素,提出了相应的解决方法。The gas overflow type of coaxial line phase water detector converts the oil-water-gas three-phase flow measurement into oil-water two-phase flow measurement to a certain extent through gas-liquid separation, thus reduces the influence of the gas flow on liquid and moisture measurement and improves the accuracy of reservoir characteristicsjudgement. The test of Bei 301 in Hailar oilfield block site and the comparative analysis show that the gas overflow type of coaxial line phase water detector can improve the flow rate and moisture measurement precision in the low yield oil wells and can realizes the production of gas analysis. In addition, the main influence factors of moisture instruments and the corresponding solutions are summarized.
