The intelligent gas storage system based on cloud platform is designed with the goal of safely and intellently injection and collection of natural gas intelligence in underground gas storage. The infrastructure layer of the system installs the natural gas sensing module in the injection and extraction wells of the underground gas storage reservoir. The natural gas sensor module collects natural gas concentration, flow rate and hydraulic pressure data from the injection and extraction well. The collected natural gas data is transmitted to the wellhead safety control module. The wellhead safety control module uses the intelligent control algorithm of proportional integral differential(PID) neural network of the technology layer to control the wellhead of the injection and extraction nells safety valve shut-off of the injection and extraction well in the underground gas storage reservoir to ensure the safe production of the underground gas storage reservoir. The whole process of intelligent gas storage is completed in the business layer of the system. The business layer combines engine module, development tool module, support module, and management module to work together to provide services for cloud platform users. The system reduces the resource consumption of the cloud platform and improves the computing efficiency of the cloud platform through the virtual machine migration control method. The system test results show that the designed system can intelligently control the wellhead safety valves of injection and extraction wells in underground gas storage to ensure good natural gas injection and collection.
