摘要
盐穴储气库在中国正处于快速发展阶段,山东、湖北、江苏等盐矿丰富的地区均已开展盐穴储气库建库研究工作.水溶造腔技术是盐穴储气库建库技术的关键技术之一,通过介绍单井对流、单井油(气)垫对流、水平对接井开采、小间距双井单腔等几种常见的水溶造腔技术,系统性分析不同造腔技术的适宜场景以及应用情况,对比其优缺点,以期为后续盐穴储气库水溶造腔技术的选择提供参考.
Abstract
Salt cavern gas storage is rapidly developing in China,and research about salt cavern gas storage has been carried out in areas where salt mines are rich,such as Shandong,Hubei and Jiangsu.Solution mining technology is one of the key technologies in the construction of salt cavern gas storage.This paper introduces several common solution mining technologies,such as single well convection,single well oil(gas)cushion convection,horizontally butted well production,small-spaced double wells single cavity,etc.,and systematically analyzes the suitable scenarios and application situations of different solution mining technologies,compares their advantages and disadvantages,and provides reference for the selection of solution mining technology in subsequent salt cavern gas storage.
