达西流动系数
Examples
- In order to study effects of various factors on gas well productivity , this paper takes changqing gas field as an example and uses gas reservoir engineering and numerical simulation methods to qualify effect of different factors on absolute open - flow capacity in different reservoirs in respect of formation coefficient , water production , non - darcy flow coefficient , formation pressure and skin factor
摘要影响气井产能的因素多种多样，为了具体描述各因素对产能的影响，以长庆气田为例，利用气藏工程和数值模拟方法，从地层系数、产水、非达西流系数、地层压力、表皮系数等几个方面定量分析了各因素对不同储层条件下气井绝对无阻流量的影响程度。 - 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 % 。
