Research On The Response Characteristic Of The Turbine In The Twophase Flow Of Gas-liquid

In the detecting of the parameters of the oilfield production (for example, the temperature, the pressure etc), in the oilfield production. As a result, it stimulated the engineers and technicians very interesting.Wells that there was not gas in them were not nearly existed in oil field. When logged by co-mmon Slip umbrella, the result were very different to the flux was measured in the flow head. The fundamental reason was fluid that was outputted from the wells were oil-water and gas multi-flow, not twophase flow of gas-liquid. When were logging by the common slip umbrella, the multiphase of oil-water and gas entered directly the base pip, then entered the turbine meter and the turbine meter and the water cut meter. Because the coercibility of the gas, it was very difficult to obtain the flux of the twophase flow of gas-liquid from the mathematical model of the multiphase of oil-water and gas. Therefore, the flux was very difficult to be accurately measured in the multiphase of oil-water and gas.Bubbling umbrella was a new slip umbrella. Because the mechanical structure of bubbling umbrella, it had the effect of knockout of gas-liquid. The bubbling umbrella decreased the affection on the flow gaging in log. Experiment was made in the lab of the measurement of multiphase .The tap water simulated the fluid that output from the well, The air simulated the gas output from the well. The experiments were selectively making by common umbrella and bubbling umbrella。The response curves were obtained through the experiment。The response curve of the tubine was seriously affected by the air when the slip umbrella was common mbrella, but the response curve of the tubine was lightly affected by the air when the slip umbrella was bubbling umbrella. The mathematical analysis of data of the experiment and the comparison of the logs also obtained the same conclusion.
