Abstract Oil–air–water three-phase flow patterns in small-diameter vertical measurement channels are complex, making it difficult to establish techniques for interpretation of logging information. In this study, dynamic experiments involving oil–air–water three-phase flows were performed using a novel production logging tool that combined a petal-type turbine flowmeter, a conductance sensor, and an optical fiber sensor in a simulation well. Sensor response characteristics were researched, and a new method of measuring the oil–air–water three-phase flow rate was proposed. The measurement range and resolution of the gas flow rate were 3–20 and 1 m3/d, respectively, and the relative error range of gas flow rate interpretation was 5–10%. The measurement range and relative interpretation error range of the total liquid flow rate were 10–60 m3/d and 5–10%, respectively. The measurement range and resolution of the water cut were 50–100% and 2%, respectively. The absolute error range of interpretation of the water cut ranged from 3.2% to 5%. Currently, the technique is valid for laboratory use under ideal conditions.

一种测量油-气-水三相流量的新方法

摘要 小直径垂直测量通道油-气-水三相流型复杂，测井信息解释技术难以建立。在这项研究中，使用一种新型生产测井工具，在模拟井中结合了花瓣式涡轮流量计、电导传感器和光纤传感器，进行了涉及油-空气-水三相流的动态实验。研究了传感器响应特性，提出了一种测量油-气-水三相流量的新方法。气体流量的测量范围和分辨率分别为3-20和1 m3/d，气体流量解释的相对误差范围为5-10%。总液体流量的测量范围和相对解释误差范围分别为 10-60 m3/d 和 5-10%。含水量的测量范围和分辨率分别为 50-100% 和 2%。含水率解释的绝对误差范围为 3.2% 至 5%。目前，该技术在理想条件下适用于实验室使用。
