摘要
哈参 1井是吐哈盆地煤层气勘探的第一口实验井 ,该井煤层气测试根据不稳定试井原理 ,采用注入 /压降测试技术 ,经过微破裂实验、注入 /压降试井和关井三个步骤 ,采用平衡压力 -标记法确认井下关井 ,运用高精度电子压力计 ,取全取准了各项资料 。
Ha 1st testing of is the1st experiment well for exploration of coal bed gas in Tuha basin.Based on no stabilized well test principle,adopting testing techniques of injection/drop down testing through three steps—microfracturing experiment,injection/pressure drop down and shutting,and equalized pressure record for shutting with high precision electronic pressure gauge,the techniques gained information in detail and acquired the succeeds in logging of coal bed gas in Tuluofa Hami basin.
