| 摘 要： | 水驱气藏气水界面的稳定运动及均匀推进，对于气井稳定正常生产，提高气藏采收率有较大的影响。文中考虑具有一定倾角的均质各向同性的边水气藏，在原始气水界面为一水平面的情况下，利用气，水地层渗流的基本规律，从理论上详细推导了保护气水分界面稳定运动的气体渗流速度应满足的条件，同时为研究边水气藏中气井的合理产量的确定提供了一个可供珠依据。

| Abstract: | Stable movement and uniform advancing of gas-water interface are important for stable production of gas well and improvement recovery of gas reservoirs.In this paper,if edge-water gas reservoir is of homogeneous isotropy and initial gas-water interface is horizontal,we derived out condition of gas seepage velocity of stable movement for gas-water interface with basic law of Darcy seepage,the same as,proposed conclusion in this paper presented basic for confirming reasonable production of gas well in edge-water gas reservoirs. |
