摘要
盐穴储气库以其独特的优势在世界范围的石油工业领域中受到越来越多的重视。以一定的形状在盐层内建造一个地下储气溶腔,是一项复杂的系统工程。结合我国在盐层建设储气库的特点,围绕造腔设计的腔体目标和实施工艺,对盐穴储气库造腔工艺技术进行了全面的论述。通过对储气库腔体形成过程的分析,从造腔工艺、腔体控制与检测方法等方面,提出了造腔井型、水循环方式、溶腔步骤、两口距调节方式、形状控制方法、顶板保护工艺、密封检测、腔体稳定性等多项技术,同时推荐了造腔管柱组合方式、注水流量确定方法和保持腔体稳定的措施,对盐穴储气库造腔设计和施工有一定的指导意义。
For its special advantages, the salt cavern gas storage is attracting more and more attention in the worldwide oil and gas industry. It is a complex and systematic project to build a certain shape salt cavern by means of leaching. Based on the characteristics of the salt cavern gas storage built in the bedded salt formation in China, this paper fully discussed the application of salt dissolution on the design of gas storage cavern. Through analysis of the forming mechanism of gas storage cavern, the following techniques were put forward from the view of salt dissolution, shape control and detection as follows, the corresponding well type to salt cavern, the circulation measure, steps of solution mining, adjusting of leaching pipeline, the shape control techniques, roof protection, sealing detection, and cavern stability, etc. And the pipe string assembly for leaching, the method to determine the circulation rate, and the measure to keep cavern stability, are also recommended. This paper is of guiding significance to the design and construction of salt cavern gas storage.
