The Research On Flow Rate Characteristics Of The Coaxial Line Water Detector Based Phase

Depending on the coaxial line water detector based phase, the flow measurement on the Gas-liquid two-phase flow is researched in this paper.It is significant for the Gas-liquid two-phase flow measurement in the oilfield development, especially on the Offshore oil field and land-based oil field. Fracturing and water shut-off are the effective measure to increase oil well. The dynamic data of production logging obtained from the water detector provided a basis for the fracturing , water shut-off and the profile control measures. In the general oil field producing progress, gas-liquid two-phase mixture is the most output. Because of the different physical property of the Gas-liquid two-phase flow, the Gas-liquid two-phase flow pattern and all kinds of parameters will change a lot when the temperature, pressure and flow rate of fluid mixtures are different. So it is difficult to measure the split-phase flow of Gas-liquid two-phase flow. The rate of flow is usually measured by Turbine Sensors, which cannot measure the rate flow accurately because of the characteristics itself. So the it is needed to remove the impact of gases on the flow measurement as soon as possibly. A new type bubbling umbrella is used in the experiment in this paper, which can reduce the effects of gas on the turbine sensor gradually.
