摘　　要：保压取样技术能够直接采获保持原始压力状态的样品,对于计算油气含量、资源储量、分析储层性质具有重要作用。本文重点对国内保压取样技术在天然气水合物、石油天然气、煤层气以及深海水样分析等领域的应用情况进行了详细介绍,指出了我国发展保压取样技术的重要性。Pressure-holding sampling technology can directly obtain samples that maintain the original pressure state, and plays an important role in calculating oil and gas content, resource reserves, and analyzing reservoir properties. This article focuses on the application of domestic pressure-holding sampling technology in the fields of natural gas hydrate, oil and gas, coalbed methane and deep sea sample analysis, and points out the importance of my country’s development of pressure-holding sampling technology.
