How to determine water and sand accumulation in oil pipeline routes
Thread Content
I would like to ask the experienced seniors here how to determine the locations of water and sand accumulation in crude oil pipelines. If it is to detect water accumulation, are there any wireless sensors or detectors similar to pigging devices that can accomplish this? In other words, such devices could float along with the crude oil inside the pipeline and send electrical signals when abnormal levels of water accumulation are detected, for example by recording information such as natural coordinates and the relative level of water content.
Water and sand accumulation must occur at the relatively lower level of the pipeline – is it still necessary to conduct inspections?
In principle, it should be at a relatively low level. But in reality, a pipeline should have several \"minimum\" points along its entire route, on various geometric curves; these minimum points are at different distances from the source, and therefore the accumulation of water and sediment there should also be different. What I want is a relatively accurate assessment of the amount of water and sediment accumulated, so that I can take subsequent actions. Rather than just knowing that this situation will definitely occur at a relatively low level, because knowing it is not the goal.
What is desired is a relatively accurate assessment of the amount of water and sediment accumulated, so that the pipes can be cleaned regularly.
Regular pigging is a good solution, but currently, several submarine pipelines in China use balls instead, let alone pigging.
