[Abstract]:Gas collecting stations play an important role in gas field development. Nowadays, gas gathering stations have many modules, large area, long construction period, large amount of construction, high operating cost and chaotic data management. The information exchange and management efficiency among the systems are low, the degree of intelligence is low, and it is difficult to realize the complete unattended field. Aiming at the general problems of gas collecting stations and combining the special environment of gas gathering stations and the complex diversity of field equipments, and based on the production needs of gas gathering stations, this paper puts forward a design scheme of priming gas collection stations. The prizing control system of gas collecting station based on Siemens PLC (S7-300) is developed. The key technology to realize the station control system is deeply studied, and the data acquisition and intelligent monitoring part of the station control system is improved and optimized. In this paper, the process flow and automatic control technology of gas collecting station in natural gas development are analyzed firstly. Combined with the characteristics of production technology and the function requirement of control system, the priming design of gas gathering station is carried out. An intelligent monitoring system based on PLC and its hardware and software integration scheme are proposed. Secondly, this paper improves the safety and effectiveness of compressor control system in the design of digital gas collecting station. The type selection of separator is carried out, and the pneumatic regulating valve is designed in the process, which makes the separator safe and convenient, and realizes the function of remote monitoring and automatic drainage. The desulphurization process was improved and the control function was optimized to improve the desulfurization efficiency and production safety. At the same time, a new and high precision natural gas flow statistic method based on PLC, the corresponding PLC flow metering program and configuration monitoring picture are proposed. Aiming at the characteristics of dispersed gas field, difficult comprehensive management and various production data, a scheme of data integration between different systems based on OPC technology is put forward, which greatly improves the production management and data interaction level of gas gathering station. Finally, the PLC control system and the configuration monitoring system are developed on the basis of deeply studying the key technologies of the gas gathering station pry control system. The remote monitoring and management functions of the gas gathering station production are realized, and the safety and reliability of the system are analyzed. The software and hardware of the system are debugged and simulated. The results show that the natural gas station control system achieves the expected goal, effectively standardizes the production of the gas gathering station, saves the management cost, and realizes the centralized monitoring and control of the production and management of the gas gathering station. The intelligent degree of unattended on the spot has been achieved.
