盐穴地下储采技术

Underground Storage and Production Technology of Salt Cavity

地下盐穴除了处置工业碱渣与核废料,还可进行天然气、石油、氦气等能源的储采。为了加强天然气产供储销产业链中“储气”环节的建设、建立石油地下储备库、减少气田中氦气稀缺资源的浪费,在总结国内金坛盐穴储气库建设运行成功经验与国外石油、氦气储存技术现状基础上,提出由溶剂注采方式、阻溶剂类型、造腔井型与溶解方式,以及不同储存物质的注采工艺等为研究内容的盐穴地下储采技术。为天然气、石油、氦气的地下储存提供技术方法,对盐矿资源综合利用、加快储气库调峰设施建设、探索石油与氦气地下储存具有重要意义,应用前景广阔。

Except for industrial caustic sludge and nuclear waste disposal,underground salt cavity is feasible for storage and production of energy like natural gas,oil and helium etc.In order to strengthen storage in natural gas industry chain,construct underground oil reserves and reduce the scare resource waste of helium in gas fields,on the basis of successful experiences of Jintan salt cavern storage construction and overseas research status quo on oil and helium storage,underground salt cavity storage technology consisted of injection and production methods of solvents,solvent resistance type,solution mining well-type and dissolution methods and injection-and-production process of different storage materials is proposed to provide methods for natural gas,oil and helium storage.The technology is significant for integrated utilization of salt mine resources,speeding up storage construction and exploring underground oil and helium storage,which is of a broad prospect.
