本文在应用(美)卡兹天然气压缩系数图版求得天然气井不同井深压缩系数的基础上,设计、绘制了由气井井底流压和井深,直接查得天然气压缩系数的诺模图,导出了相应的压缩系数数学模式,并在排水采气工艺的设计、试验中验证了其可靠性。
Based on the calculation of the different well depth compression coefficients of natural gas wells by applying the Katz natural gas compression coefficient map, a new nomogram of natural gas compression coefficient is designed and drawn from the bottom hole flow pressure and well depth of the gas well. Correspondingly, The compression coefficient mathematical model, and in the drainage gas production process design, test to verify its reliability.
