- 摘要:
- 泡沫清管器通过结蜡原油管道内的蜡层突起时产生压力波，传递至上、下游采压点形成时间差，据此对泡沫清管器在管道内的实际位置进行跟踪。结合非洲乍得原油管道的实际清管过程，将计算模型与实际结果比较，满足要求。采用压力波法跟踪泡沫清管器解决不带跟踪器的泡沫清管器进行跟踪的问题，有助于管线安全清管作业及制定合理的清管输油方案，适用于结蜡较多的具有压力采集系统的原油管道，随着压力采集点的增多，跟踪准确度越高。
When foam pig passes wax layer protuberance in crude oil pipeline with wax deposit, pressure waves arise from the pig blockage, these waves are transmitted to the upstream and downstream pressure acquisition points, which will form a time difference. The time difference is used for tracking the foam pig position in crude oil pipeline. Compared with data obtained from the Chad crude oil pipeline in Africa, the results obtained by the calculation method are similar to actual ones. This method can solve the problem that foam pig without tracker can not be traced and it is suitable for crude oil pipeline with pressure acquisition system and much wax deposit in it and the more pressure acquisition points in pipeline system, the more accurate tracking can be obtained.
