摘　　要：CO_2致裂技术是应用液态CO_2瞬间气化产生冲击,达到预裂煤层、岩层的目的,充装阀是CO_2致裂器的重要部件。设计了一套简便并实用的充装阀气密性试验装置,利用该装置对10支充装阀进行了试验,并实际充装液态CO_2进行了验证,结果表明,在试验装置上能够保持很好气密性的充装阀,20 h实际泄漏量均能控制在5%以内,性能稳定。The CO2 fracturing technology is an important part of CO： fracturing. A simple and practical gas-tight test device for filling valve is designed. The test results show that the filling valve with good air tightness can be maintained on the test device,and the actual leakage rate can be controlled within 5% and the performance is stable.
