With the gradual development of oil and gas exploration and development into deep and complex formations,the risks and rewards faced in the drilling process are increasing.The market increasingly needs software that can integrate monitoring and control to ensure safe and efficient drilling.Using managed pressure drilling technology can effectively control the pressure in the gas production process and make it more convenient to deal with equipment failure.It can realize real-time monitoring of fluid pressure and density changes in the production process,effectively reducing potential safety hazards,preventing the occurrence of downhole accidents,and providing a guarantee for the safe and stable production of oil and gas wells.The Managed Pressure Drilling Simulation and Control Software aims to obtain drilling-related information from logging,PWD(Pressure While Drilling),MWD(Measure While Drilling),pressure control,and other equipment.It establishes hydraulic models to calculate wellbore pressure,flow,and other parameters.This software adopts client/server architecture,which allows multiple clients to connect to a server simultaneously and synchronize data.The client data synchronization effect has been verified on-site,meeting the needs of single machine use and facilitating network connection.The results indicate that this software can accurately simulate and calculate various drilling parameters,ensuring safe and efficient drilling.The centralized analysis,processing,and remote control have created a good foundation for pressure control drilling,transitioning from on-site engineer processing mode to a data platform-based approach.This lays the foundation for interconnectivity between multiple on-site pressure control drilling equipment on one platform,effectively promoting the development of intelligent pressure control drilling.
