原油的含水率已作为原油的一项质量指标作出了规定。目前要求商品原油含水不大于1％,出口原油不大于0.5％。从管道输送和车船转运来说,输运高含水的原油不仅要多消耗动力和热能,而且会给炼厂加工带来麻烦,所以真实地测出原油中的含水量很有必要。 管道输油是原来原转。即按油田所交的原油质量原样转输给用户或交给车、船二次转运。但是,在管道局管理的管线中有的出现差异。即油田给首站交油时化验的含水量小,而经管道输送后交用户时含水量增大,并有超过允许误差范围的现象(详见表1)。
The moisture content of crude oil has been stipulated as a quality indicator of crude oil. Crude oil is currently required not more than 1% water content, export of crude oil is not more than 0.5%. From pipelines and transhipment, the transport of high-water-content crude oil not only consumes more power and heat, but also causes problems for refineries. Therefore, it is necessary to truly measure the water content of crude oil. Pipeline oil is the original original turn. That is, the quality of the crude oil delivered by the oilfield is transferred to the user as it is or to the vehicle and the ship is transshipped twice. However, there are differences in the pipeline managed by the pipeline administration. That is, when the oil field gives the first station the oil content at the time of oiling test is small, the water content increases when it is handed over to the user after passing through the pipeline and there is a phenomenon exceeding the allowable error range (see Table 1 for details).
