摘　　要：为考察现有光纤持气率计在油气水三相流中的响应特性,采用多相流标定装置对其进行测定,系统研究光纤持气率计在油量固定不变含水量不同条件下的持气率响应规律。实验结果表明,当油量为5m3/d、气量小于10m3/d时,持气率随含气量的增大而增大,二者线性变化程度较低;而气量在10～35m3/d之间变化时,持气率随含气量的增大而线性增大。In order to investigate the response characteristics of optical fiber gas holdup sensor to oil-gas-water three-phase flow, the response laws of the sensor were systemically investigated by using multiphase calibration equipment at constant oil content and different water contents. The results show that the gas holdup increases while increasing the contents of gas when the content of oil is 5 m3/d and the contents of gas are less than 10 m3/d, however, the degree of linearity between gas holdup and gas content is low. It is also found that the degree of linearity increase between gas holdup and gas content is relatively high when the content of gas is in the range of 10 to 35 m3/d.
