Investigation of Dominant Factors Influencing High-speed Non-Darcy Effect in Gas Wells
摘要
Abstract
Practice in gas reservoir development has shown that the high-speed non-Darcy effect has a significant impact on gas well productivity.However,the degree to which high-speed non-Darcy effects impact different gas reservoirs varies.For gas reservoirs with lower pressures,the high-speed non-Darcy effect becomes more pronounced with increasing gas well production rate.For gas reservoirs with higher pressures,the same level of gas well production rate may not cause strong high-speed non-Darcy effects due to the strong gas compression,higher density,viscosity,and lower natural gas seepage speed under higher formation pressure.Sensitivity analysis of the primary factors influencing non-Darcy effects is conducted based on the gas well productivity equation and Reynolds number equation,including reservoir properties and gas properties.The Darcy/non-Darcy flow boundary is established based on the critical Reynolds number,and a Darcy flow chart is created for natural gas.The chart can be used to determine the strength of non-Darcy effects and provide guidance for setting production constraints for gas wells.关键词
