| 摘 要： | 由于致密低渗气藏气体渗流存在启动压力梯度,而苏里格气田属于典型的低渗和特低渗河道砂体气田;为了研究启动压力梯度对苏里格气田气井有效供气半径的影响,本文通过实验得出了苏里格气田苏6井区有效渗透率与启动压力梯度的关系,并结合气体稳定渗流理论推导出了有效供气半径的计算公式,得到了不同渗透率和启动压力梯度及一定井底压力下有效供气半径的理论图版。通过实例计算表明相同配产量下启动压力梯度对有效供气半径的影响比较明显。

| Abstract: | Because the start-up pressure phenomenon occurs in gas flow in tight gas field.However sulige gas field is particularly tight gas field.In order to research the effect on the drainage radius of gas well of sulige gas field about start-up pressure gradient.The relation between effective permeability and start-up pressure gradient is studied in laboratory.The calculation formula for drainage radius of gas well is deducted form stable percolation theory. Theory chart is given out under different effective perm... |
