多数情况下,原油从集油站或泵站输往脱水站不得不流经一段长距离管道。大量的伴生水经常被充分乳化,使这种油水混合液呈现非牛顿流体特性。设计输送这种乳状液的管道有几种可行的估算方法。不过,对已建管道的输送量,尤其是对于允许一条管线停输而对另一条管线暂时增加输送量的情况,经常要作快速估算。鉴于混合物的非牛顿流体特性,惯用的计算方法不再适用,同时一般工程师也不很熟悉处理非牛顿流体问题,而且为了测定混合物的流变特性需要的复杂仪器,一些集油站或管理中心是不具备
In most cases, the crude oil from the petrol station or pumping station to the dehydration station has to flow through a long distance pipeline. Large amounts of associated water are often emulsified, rendering this oil-water mixture non-Newtonian fluid. There are several possible ways of designing a pipeline to deliver this emulsion. However, often rapid estimates are required for the volume of pipeline already built, especially for temporarily allowing one pipeline to be shut down while another pipeline is being temporarily increased. Due to the non-Newtonian fluid properties of the mixture, the usual computational methods are no longer applicable and the average engineer is also not familiar with handling non-Newtonian fluid problems and some gas gathering stations or management centers are required to determine the rheological properties of the mixture Do not have
