Abstract:
The study on transporting multi-blended crude with multi-formula and properties at the ordinary temperature has been made. The isoline, based on the properties of mixed oil, the correspondent law of blended crude's property and formula, and the transportation requirements to crude oil's property at the ordinary temperature, has been drawn up, and the formula scope for the ordinary temperature transportation has been presented. To ensure the calculated start-up pressure less than the allowable pumping pressure, the start-up pressure for the blended crude with the poorest property has been checked up.
