本文通过对气井系统试井测试资料的解释分析,利用二项式和指数式拟压力法计算出气井产能方程并求取相应气层无阻流量及合理生产压差下的气井产能;同时论述了压降法计算井控储量在气井不同开采阶段的应用;最后预测了未来三年的气井IPR曲线,充分说明系统试井技术在气井评价中的突出作用。
Based on the interpretation and analysis of the well test data of gas well system, the paper calculates the well productivity equation by using binomial and exponential pseudo-pressure method and obtains the gas well productivity under unobstructed gas flow and reasonable production pressure difference. At the same time, Down method to calculate the application of well control reserves in different production stages of gas wells. Finally, the IPR curves of gas wells in the next three years are predicted, which fully demonstrates the prominent role of the system well test technology in gas well evaluation.
