对多种配比、组分油物性差异较大的多组分混合原油常温输送的工艺进行了研究。根据混合油物性、组分油物性与配比的相关规律以及常温输送对原油物性的要求,绘制了等值线图,给出了常温混合输送配比域。为保证计算的启动泵压小于允许泵压,对物性最差混合油的启动泵压进行了校验。 The technology of transporting multi-component mixed crude oil at room temperature with a wide range of formulation and composition properties was studied. According to the physical properties of the mixed oil, the composition of the oil properties and the ratio of the law and the physical properties of crude oil delivery at the request of drawing a contour map, given the room temperature mixed delivery ratio. To ensure that the calculated start-up pump pressure is less than the allowable pump pressure, the start-up pump pressure of the poorest mixed oil is checked.
