赴美储气库调研及其启示

为了了解北美地区地下储气库发展状况，吸收国外储气库在研究、设计、建设和管理等方面的经验，提高我国储气库设计、建设和管理水平，北京华油天然气有限责任公司组织有关单位，对美国储气库从研究、设计、建设和管理等方面进行了现场考察和调研。文章对美国储气库现状、储气库安全和运行管理、储气库特色技术都作了较详细地介绍，并总结出了一些启示，进而提出了我国储气库发展的建议：①在储气库的库址比选前，应对储气库的用户市场进行调查；②应优先选择废弃的气藏或凝析气藏作为建库的库址；③应强化储气库建设前的评价和研究工作的力度，以便选择技术上和经济上最优的方案；④老井封堵的思路值得借鉴。

RESEARCHES ON AMERICAN UNDERGROUND GAS STORAGES

Beijing Huayou Natural Gas Company Limited has led a group of Chinese researchers and designers to America for an onsite investigation and study of research, design, construction, and management experience on underground natural gas storage. The activity was targeted toward learning more information on the development situation of underground gas storage in North America area, as well as foreign experience in research, design, construction, management, etc. After an integrated analysis on the current situation, security system and operation management and advanced technologies of American underground gas storages, some suggestions were proposed as follows for further developing Chinese underground gas storages: 1) a comprehensive investigation should be performed on gas consumers and gas market before siting a gas storage; 2) depleted gas reservoir or condensate gas reservoir should be preferentially adopted as a site for underground gas storage; 3) to facilitate the selection on optimal technical and economical proposal, preliminary appraisal and research works should be highlighted and strengthened; 4) the approaches on plugging of old wells should be learnt.
