To investigate corrosion and resulting changes in the sealing performance of premium connections corrosive CO2 environments, we carried out a simulation analysis their secondary current distribution structural mechanics based on multi-physics field coupling. A finite element calculation model Ф88.9 mm × 6.45 taper–taper (steel grade P110) was established using COMSOL6.0 general software. By analyzing laws under different environmental parameters, five internal pressures tensile displacements were set. We simulated operating conditions module. density conditions, before after quantitatively evaluated seal strength index. The results show that is higher at torque shoulder connections, which more susceptible to damage. As pressure increases, inner wall column threads, highest rounded corners root thread, also likely be damaged. Under pressures, although meets criterion, corroded ones significant reduction performance. this study provide reliable theoretical basis for research environments.

In order to reduce CO₂ emissions from industrial processes, countries have commenced the vigorous development of CCUS (carbon capture, utilization and storage) technology. The high geographical overlap between China’s extensive coal mining regions CO2-emitting parks provides an opportunity for more efficient reduction in CO2 through Enhanced Coal Bed Methane (ECBM) Recovery use with Furthermore, proximity these allows a shift transportation mode pipelines tanker trucks, which are cost-effective logistically advantageous. issue must also be considered accurately assess constructed cost function source–sink matching model implementation ECBM. model, when conjunction actual situation Shanxi Province, enables emission sources sequestration sinks province realized ArcGIS 10.8 software, transport routes derived as result. After analyzing results, it is found that accounts relatively small proportion total cost. fact, CH4 price has larger impact on cost, replacement ratio not conducive profitability.
