全球各大油气公司的上市储量评估是基于2010年美国证券交易委员会颁布的SEC储量评估准则进行的。该版准则明确了可以利用"可靠技术"来扩展评估证实储量的技术类型。自准则颁布以来，中海石油（中国）有限公司不断地尝试探索"可靠技术"在天然气上市储量评估中的应用，形成了多项"可靠技术"，并逐步得到了国外第三方评估审计公司的认可。文章讨论了"可靠技术"的含义，结合国内外研究列举了"可靠技术"的披露原则及条件，通过实例展示了近年来在南海西部气田SEC储量评估中所使用的如利用地球物理信息确定含气范围、利用压力资料计算动用储量、平台压缩机降压提高气田开发后期采收率技术等多项可靠技术。近年来中海石油通过对"可靠技术"的合理应用，使得评估结果更加接近气田实际开发情况，保障了评估结果的客观准确以及公司储量替代率的稳定，为国内天然气田的上市储量评估提供了可参考案例。

Reserve assessment of major oil and gas companies around the world is based on the SEC Guidelines issued by the US Securities and Exchange Commission in 2010. This edition expanded the types of "reliable technology" that can be used to determine proved reserves. Since the publication of the guidelines, CNOOC has continuously tried to explore the application of "reliable technology" in the assessment of natural gas reserves, and has formed a number of "reliable technologies" that have gradually been recognized by third-party evaluation agencies and auditing companies. The article discusses the meaning of "reliable technology". It combines domestic and foreign studies to enumerate the disclosure principles and conditions of "reliable technology", and demonstrates some "reliable technology" which has been widely used in the evaluation of SEC reserves in the western South China Sea gas field in recent years, such as the use of geophysical information, the use of pressure data to calculate reserves, the installation of a platform compressor to reduce the pressure and improve the recovery technology in the late stage of gas field development. In recent years, through the application of "reliable technology", CNOOC has made the evaluation results closer to the actual development of the gas field, which guaranteed the objectivity and accuracy of the evaluation results and the stability of the company's reserve replacement rate. It provides a reference case for the domestic natural gas field reserve assessment.
