CSCT法在金坛老盐腔储气井腔体及井筒气密封测试中的应用

Application of CSCT Method on Old Salt Cavern Transformed Gas Storage Cavity and ShaftTightness Test in Jintan

为缩短建库时间、节约投资成本,充分利用地下已有空间,将已废弃的老盐腔改造成储气库。盐穴储气库密封性检测及评价技术是一项涉及到多学科的复杂技术。在借鉴国外盐穴储气库密封检测技术基础上提出CSCT方法。以江苏省常州市金坛盐矿区某井盐穴储气井为例,对CSCT方法的测试原理及施工流程进行了介绍。结果表明,该方法具有现场操作性强、试压费用低、评价结果准确合理等特点。

To cut down gas storage construction period,save capitalized cost,take full advantage of existing underground space,should transform abandoned old salt cavern into gas storage.Salt cavern gas storage tightness checking and assessment is a complex technique involved many disciplines.On the basis of reference from abroad salt cavern gas storage tightness checking technology has proposed the CSCT method.Taking well salt cavern gas storage in the Jintan salt mine,Changzhou City,Jiangsu Province as an example has introduced testing principles and operating procedure of CSCT method.The result has shown that the method has advantages of strong site operability,low pressure test expenses and assessed result accurate and reasonable.
