Integrity management system and risk identification of gas reservoir type underground gas storage

In order to ensure the safe operation of gas reservoir type gas storage and guarantee the normal operation of natural gas storage,distribution and peak shaving system,the integrity management and risk identification were carried out on the gas reservoir type gas storage.It was clarified that the objects of integrity management of gas reservoir type underground gas storage were three modules including the ground station system,gas storage wells and geological body,and the integrity management of geological body was the characteristics and difficulties of the integrity management of gas reservoir type gas storage.Based on the idea of pipeline integrity management,a six-step cycle of the integrity management of gas reservoir type gas storage was put forward,including the data acquisition,unit identification,risk assessment,integrity evaluation,repair and maintenance and efficiency evaluation.The research results show that the integrity management of the three modules is the basis of the integrity management of the gas storage,the integrity management of the geological body is the focus of the integrity management of the gas storage,and the six-step cycle runs through the integrity management of the gas storage type gas storage.in each work segment.
