摘　　要：在天然气的勘探开发中有许多工程地质问题都涉及到纯天然气井动气柱压力计算,但现在的动气柱压力计算方法较繁琐且应用不太方便。文中介绍的动气柱压力计算新方法,推理严谨、计算简便、计算精度高,而且可以很方便的通过井口压力、井口密度计算任一井深的相应参数值,因此本方法具有很高的使用价值。During the exploration of natural gas, there are many problems about engineering and geological that relate to the pressure calculation of the natural gas in dynamic state. But the method to calculate the pressure of the pure natural gas in dynamic state is very complicated at present so that the method is not convenience. In this article, the new method to calculate the pressure of the pure natural gas in dynamic state is logical and simple and accurate. Using the new method can calculate the pressure in any depth of the well. So the application value of the new method is very high.
