| 9. | The result shows that 1 ) formation coefficient is a main factor . 2 ) boundary and formation heterogeneity have much effect . 3 ) water producing gas wells should be produced reasonably according to gas production policy with water controlling technique so as to avoid watered out . 4 ) with increase of non - darcy flow coefficient , gas well productivity decreases . 5 ) in the process of gas well production , formation energy should be used reasonably . 6 ) when skin factor increases from 0 to 6 , its open - flow capacity is 60 % - 70 % of that without pollution
研究表明：地层系数是影响气井产能的主要因素；边界和地层非均质对气井产能影响很大；对于产水气井，应严格按照控水采气技术政策合理开采，避免水淹；随着非达西流系数的增大，气井产能不断降低；在气井的生产过程中，必须合理利用地层能量；当表皮系数由0增加到6时，其无阻流量为不受污染时的60 % ~ 70 % 。 |
