Hua-Ge Mixing Conveying Oil Thixotropy Petroleum And Natural Gas

On-stream Hua-Ge438.887km, the caliber isφD355.6mm, year oil quantity is300×104tons, conveying pressure has provided8.0Mpa station block5. Oil line mixing conveying oil plans to stop transmission and fault shutdown is inevitable. Below the design throughput conditions at run time, with the shutdown process oil, crude will strengthen the non-Newtonian properties, and then start the pressure increases, the pipeline will pose a threat to the safety of the pipeline transport capacity of the recovery process and pump characteristics, performance-related, and crude oil are closely related to thixotropy. Therefore, the transportation of crude oil thixotropy, accurately and then start the process characteristics, calculate the pipeline at various throughput, in different seasons of the safe shutdown time, then start pressure ensures safe on-stream, running smoothly.
