地下储气井(以下简称储气井)是指以储存压缩气体为目的的地下立式管状承压设备。主要用于汽车加气、天然气调峰和工业储气等。自二十世纪90年代中期四川首先开发应用储气井以来,使用中因为固井质量不过关,出现了CNG泄漏、套管爆裂和地上井口装置上窜或套管下沉等现象。可见固井质量的优劣,直接决定储气井的使用寿命。因此国质检办特[2008]637号文《关于加强地下储气井安全监察工作的通知》明确规定新建储气井必须进行固井
Underground gas storage wells (hereinafter referred to as gas wells) refers to the storage of compressed gas for the purpose of underground vertical tubular pressure equipment. Mainly used for car refueling, natural gas peak shaving and industrial gas storage. Since the first development and application of gas storage wells in Sichuan since the mid-1990s, CNG leakage, casing burst, casing channeling and casing sinking have appeared due to poor cementing quality. Can see the pros and cons of cementing quality, gas storage wells directly determine the service life. Therefore, the State Quality Inspection Office [2008] No. 637 “on strengthening the safety supervision of underground gas storage wells” clearly stipulates that the new gas wells must be cementing
