Research on Classification Management Method of Xushen Gas Field

Abstract

Xushen gas field not only exploits volcanic gas reservoir, but also develops glutenite reservoir. In the production process, there are great differences in gas well productivity, formation pressure and single good reserves. By establishing the fine management mode of four types of wells, the “one type, one method, one well, one policy” has been realized. It mainly forms the multi-factor comprehensive production allocation technology with “two optimizations and three control” as the means, improves the winter peak regulation mechanism of withdrawal, supplement and shortterm emergency peak shaving, determines the drainage gas production technology to meet the current development needs, explores the treatment method of easy freezing plugging well with “three-step” as the main method, and effectively governs Low-yield and low-efficiency wells.
