Study on Flow Measurement Model of Gas-Liquid Two-Phase at Inlet of Wellhead for the Exploitation of Natural Gas Hydrate

Abstract:

CO2 injection is an effective method for exploitation of natural gas hydrate. The injected CO2 flow measurement at inlet of wellhead is a gas-liquid two-phase flow for the exploitation of natural gas hydrate. The numerical simulation of gas-liquid two-phase flow is carried by FLUENT software in combination with a V-cone flowmeter. The rate of flow of fluid and the turbulent kinetic energy were analyzed for V-cone flowmeter. The efflux coefficients of V-cone flowmeter are calculated for the different equivalent diameter ratio. Based on homogeneous flow model, thoughts of James and the curves of volume flow, the lasted modified model of gas-liquid two-phase flow is obtained. The relative error is only 0.35%. It is feasible to measure the flow of gas-liquid two-phase flow by the lasted modified model, which will improve the exploitation of natural gas hydrate.
