Abstract: In allusion to transporting issues for blending proportion of the crude oil imported and that produced in Shengli Oilfield, characteristics in blending process of "oil blending in tank" and "blending in discharge manifold of oil-feed pump" are analyzed. Transportation program is proposed that "blending in outlet manifold of oil-feed pump" combined with comprehensive regulating technique can realize multi-directional blending transportation for import crude oil and Shengli Crude oil. Practice demonstrates that this precision process has better feasibility and bright application prospect.
