Research on wet gas metering for regulating valve combination based on Gaussian process regression
摘要
Abstract
Objective This studyaimsto address the common issue of large measurement errors in gas-liquid two-phase flow caused by low single-well production and fluctuating liquid production in a gas field.Method A wet gas dual-parameter combined measurement device based on a wellhead regulating valve was designed.Through air-water two-phase flow experiments,the variations of the valve differential pressure and pressure loss under different regulating valve openings,operating pressures,gas superficial velocities,and volumetric liquid fractions were analyzed.The valve differential pressure ratio was introduced,and the relationships among valve opening,differential pressure ratio,gas Froude number,gas over-reading,and liquid-to-gas mass flow rate ratio were investigated based on experimental results.Gaussian process regression method was used to establish models for gas over-reading and liquid-to-gas mass flow rate ratio,which were then solved iteratively to calculate the gas and liquid flow rates.Result The proposed combined metering model covers a wide range of gas-liquid two-phase flow patterns,with controllable prediction errors for gas and liquid flow rates.The average relative errors for gas and liquid flow rates are 5.43%and 15.39%,respectively.Conclusion The proposed meteringmodel effectively reduces the measurement errorsin gas-liquid two-phase flow,offering a new methodology forwet gas metering,and providing technical support for the low-cost development and refined management of gas fields.关键词
