摘　　要：超高压气井井底压力计算是采气工程基础技术的一大难题 ,文中通过能量守恒方程式、真实气体状态方程式 ,应用解题思路得出推导的数学模型 ,较好地解决了 70MPa以上的超高压气井———新 85 1井的井底压力、无阻流量、地层压力计算问题 ,有显著的推广应用价值。The calculation of bottomhole pressure for superhigh pressure gas well is very difficult in gas production engineering.In this paper,the mathematical model on bottomhole pressure calculation is fetched by conservation of energy equation and gas equation.It can solve the calculation problems of bottomhole pressure,open flow potential and formation pressure of superhigh pressure gas well over 70MPa.It is worth popularizing and applying.

关 键 词：超高压气井 井底压力 计算 能量守恒方程式
