用产能试井法计算气井单井地层压力

为及时得到气井当前地层压力，为气藏地质研究和评价、动态分析、储量计算等提供依据。将气藏物质平衡方程与二次产能方程结合，建立目标函数，并采用非线性回归方法计算得到气井地层压力。实例计算表明，这种方法简便易行，结果可靠。

With Production Method to Calculate Single Gas Well Formation Pressure

For obtaining the gas well current formation pressure promptly and providing a basis for the gas reservoir geology research and appraisal, the dynamic analysis, the calculation of reserves and so on, the objective function is built by integrating material balance equation for gas reservoir with binomial productivity equation and the gas well formation pressure is calculated by using the non- linear return method. The example calculation indicated that this method is easy to do and the result is reliable.
