近年来,随着国家川气东送和西气东送项目的大力发展,江苏淮安楚州和常州金坛地区分别投入建设了两个大型的储气库项目。对储气井储气性能的检测,中石化华东工程公司测井分公司生产测井中心通过运用中子伽马测井工艺分别在完井、融盐造腔和投入使用后多次进行气密封测试,分析归纳测试的结果得出了储气井的储气性能。并结合分析测试中出现的问题及发生的原因,总结出相应的现场解决措施,进一步提高了中子伽马测井工艺在储气井中的应用。
In recent years, with the vigorous development of national Sichuan-East Gas Transmission Project and West-East Gas Transmission Project, two large-scale gas storage projects have been put into operation respectively in Chuai, Huaian, and Jintan, Changzhou. Gas storage gas storage performance testing, Sinopec East China Engineering Company Logging Production Logging Center through the use of neutron gamma logging technology, respectively, in the completion of salt into the cavity and put into use after several gas-tight test, The results of the analysis and induction test result in the gas storage performance of the gas well. In the light of the problems occurred in the analysis and testing and the reasons for the problems, the corresponding site solutions are summarized and the application of neutron gamma logging technology in gas storage wells is further improved.
