AUTOMATIC SYSTEM WITH PLC FOR MONITORING THE PARAMETERS OF A GAS WELL

Monitoring gas well parameters is essential to ensure the efficient, safe and compliant operation of natural gas extraction and transportation facilities. By monitoring critical values in real time, any anomalies can be quickly detected and corrective measures can be implemented to prevent incidents and optimize production. The monitored parameters typically include: pressure (at the wellhead and in the column), gas flow, temperature, water content or other impurities, sand or solid particle level (if applicable). Modern monitoring systems use digital sensors, data transmission through SCADA networks and analysis algorithms for rapid data interpretation. This provides complete visibility into the performance of each well and contributes to extending the life of the equipment and increasing operational efficiency. The paper presents aspects of the design and implementation of an automatic PLC monitoring system for gas well parameters. Based on the block diagram of the monitoring system, a new configuration of the placement of transducers on the well eruption head is proposed. The system’s electrical diagrams are provided, along with the PLC programming steps and the operating specifications. Additionally, details are included regarding the HMI interface, highlighting how users can easily navigate, set transducer measurement intervals, perform calibrations, or activate alarms.
