| 摘 要： | 依据地层水的赋存状态将低渗致密气藏划分为3类储层,根据不同类型储层渗流的主控因素,建立考虑滑脱效应、应力敏感性和启动压力梯度同时存在和各自组合存在时的渗流数学模型,推导出低渗致密气藏低速非线性渗流3类储层产能公式.计算表明,低渗致密气藏低速非线性渗流不同流态下,气井计算产量都明显区别于传统达西流动情况,且生产压差较大时... |

| Abstract: | Low permeability tight gas reservoirs are classified into three categories according to formation water occurrences.Mathematical models are established for seepage flow in different reservoirs by taking account of slippage effect,stress sensitivity and threshold pressure gradient respectively and simultaneously.Productivity formulas are derived for low-velocity nonlinear flow in the three categories of low permeability tight gas reservoirs.Numerical analysis shows that,compared with traditional Darcy flow,t... |
