超稠油管道内检测工艺技术研究

Study on internal testing technology of ultra heavy oil pipeline

特石管道是辽河油田唯一一条输送超稠油油品的管道。随着中国石油集团公司对管道完整性管理的不断推进,需对该条管道进行管道内检测。由于该条管道输送温度为91℃,国内现有的管道检测技术无法进行不停产检测,因而需调整该管道的运行参数,满足国内现有的管道内检测的条件。

The special stone pipeline is the only pipeline that transports super heavy oil oil in Liaohe Oilfield. With the continuous advancement of pipeline integrity management by CNPC,it is necessary to carry out in-pipe inspection of the pipeline. Since the pipeline transportation temperature is 91 °C,the existing pipeline inspection technology in China cannot perform nonstop production inspection,so it is necessary to adjust the operation parameters of the pipeline to meet the existing domestic pipeline inspection conditions.
