库尔勒—鄯善输油管道是我国第一条大落差并设有减压站的常温输送管道,首次在该管道上成功地完成了一次清管作业,掌握了库鄯输油管道结蜡及原油分层沉积规律,并对管道运行过程中结蜡的速度和以后清管周期进行了分析。找到了避免堵塞的方法,为以后的管道安全清管提供了经验。 Korla - Shanshan Oil Pipeline is China’s first large drop with a decompression station at room temperature pipeline, for the first time in the pipeline successfully completed a pigging operations, grasping the reservoir 结 oil pipeline waxing and crude oil stratification Sedimentation rule, and analyze the speed of wax deposition and the subsequent pigging cycle during pipeline operation. Found a way to avoid the blockage, and provided the experience for the safe pipe cleaning in the future.
