简化修正等时试井方法应用的局限性

APPLICATION LIMITATIONS OF THE MODIFIED ISOCHRONAL TESTING

以理论分析及气井实测资料为依据，指出原有简化修正等时试井方法应用的局限性，在此基础上，提出气井“理想”绝对无阻流量的概念，介绍了一种有利于节约测试费用、减少天然气消耗的简化修正等时试井方法。应用实例表明，该方法是有效的。

This paper points out the application limitation of the modified isochronal testing in accordance with the theoretical analysis results and practical data of gas wells, and then presents the conception of 'ideal' absolute open flow, and gives an introduction on the new modified isochronal testing, which is favorable to reduce testing expenses and decrease gas consumption. An example is used to demonstrate the new method is effective in practical application.
