Design of Remote Monitoring and Control System for Gas Well Casing-tubing Annulus
The abnormal pressure in the casing-tubing annulus of a gas well is one of the factors that seriously affect the safety production,and the condition monitoring of this annulus can provide an important basis for wellbore integrity as-sessment and subsequent operation.A remote monitoring system based on STM32 is developed for remote monitoring of abnormal pressure in the annulus of gas wells.The system realizes remote monitoring of annular pressure,temperature and pressure relief flow rate and remote pressure relief control through field controller and computer host software.The accuracy of the system is confirmed through theoretical calculations and cross-tests,providing a reference for the study of well bar-rier integrity diagnostic tools to ensure the production safety of gas wells.
