| 摘 要： | 高寒地工铖品管道冰堵现象时有发生。在管道完全堵塞情况下，采用注油试压的方法，利用注油量和压力变化计算出过油管段长度，从而确定堵点基本位置，若管道未完全堵塞，可向管道仙投放可发出信号的清管器跟踪探测；或者向管道仙发射压力波，测量其返回时间，推算管道堵塞基本位置，提出了预防管道冰堵现象的相应措施。

| Abstract: | Pipeline ice plug phenomenon often occurs in oil product pipeline in high and cold region. In case of complete plugging condition, oil injection pressure test shall be used to calculate the length of oil injecting section with injected oil amount and pressure change to define the basic location of the plugged point. In case of incomplete pipeline plugging, pig with signal sending function shall be launched for tracing detection; or emit pressure wave into pipeline to measure its return time in order to calculate basic location in pipeline pluged, in which, also provides corresponding measures for preventing pipeline from ice plug. |
