| 摘 要： | 对于底水气藏，为了防止或减缓底水锥进，通常只打开气层顶部，此时井底附近气体流动不再是平面径向流，而是半球面流；地下储气库注气时，气体从井底往地层的渗流也类似于半球面流，并且上面两种情况中井底附近均为非达西流动。然而，目前已知的文献中，尚查询不到关于考虑非达西流动的半球形气井产能公式的推导。在实际的气井计算中，若不考虑非达西，会产生很大的误差。本文对非达西的半球面气井产能公式进行推导，并通过气藏实例分析，表明不考虑非达西流动计算的气井产能将产生较大误差，用本文推导的公式进行计算更接近气井的实际情况。

| Abstract: | For gas reservoir with bottom water,in order to prevent or weaken bottom water conning,only top portion of gas reservoir is opened,and in this case gas flow in bottom hole is not radial flow but semi-spherical flow.As for gas injection in subsurface gas storage reservoir,gas flow through bottom hole into reservoir is similar to semispherical flow,and flow regime referred to the above two cases near the wellbore is non-Darcy flow.However,in those known documents,we cannot find any derived equation about gas ... |
