Embodiment Construction
[0027] This method has been successfully tried for the first time in the pressure test process of the salt cavern cavity of West 2 Well and West 1 Well in Jintan area, which belongs to our company, from December 12th to 15th, 2004. The whole pressure test process was very smooth. The pressure test results show that within 24 hours, the maximum variation of the gas-water contact depth at the production casing shoes of Wells Xi 1 and Well Xi 2 is 0.118m, and the cavity leakage rate of Wells Xi 1 and Well Xi 2 gradually decreases over time. Small, and finally stabilized at around 0 value, so the cavities of the salt cavern gas storage in Wells Xi 1 and Well Xi 2 are well sealed, and the next stage of gas injection and brine discharge can be carried out. The successful pressure tests of Wells Xi 2 and Well Xi 1 were highly recognized by peer experts, and the pressure test methods were unanimously praised by experts. This method was successfully applied in the pressure test of Well...
