| 摘 要： | 中国适合建库的地质条件为层状盐岩,造腔盐层段具有厚度小、夹层多、含盐品位低等特点,其地质结构决定了中国盐穴储气库造腔设计不能完全借鉴国外设计经验。根据近十年来盐穴腔体造腔设计和现场实践,首次提出了适合层状盐岩造腔设计关键参数的选取原则,并基于此原则编制了初步造腔设计与调整方案,以指导现场造腔实践,效果良好。在现场造腔跟踪期间,形成了造腔动态分析、阻溶剂界面监控、造腔进度跟踪及声呐测腔等一系列跟踪与监测技术,有效避免和减少了现场造腔异常并及时发现和解决造腔突发问题,保证了腔体在建造期间正常有序。研究成果可为其他盐穴储气库建设提供设计依据和技术支持。

| Abstract: | In China,the layered salt rocks are geologically suitable for the construction of salt cavern gas storages,and the leaching salt intervals are characterized by thin single layer,multiple interbed and low salt grade.Due to the geological structure,the solution mining design of salt cavern gas storages in China cannot learn from foreign design experience completely.Based on the design and site practice of solution mining in the past ten years,the principle to select the key parameters of solution mining design in layered salt rocks was put forward for the first time in this paper,and it fills the domestic blank.Based on this principle,the preliminary solution mining design and adjustment plan were prepared to guide the practical solution mining,and its application results are good.In addition,a series of tracking and monitoring techniques were developed during the on-site tracking of solution mining,such as dynamic analysis for solution mining,blanket interface monitoring,leaching progress tracking and sonar survey,so as to avoid and reduce the leaching abnormalities effectively,identify sudden problems timely and ensure the normality and order of solution mining.The research results can provide design basis and technical support for the construction of other salt cavern gas storages. |
