Optimization of Mixing Crude Oil Density for Batch Transportation Based on Sales Benefit

To improve sales efficiency from upstream pipeline companies and ensure the supply of high-quality crude oil for downstream refineries, it is necessary for pipeline companies to progressively realize the interconnection of oil and gas long-distance pipelines. Under this background, the batch transportation of different quality crude oil will be the development trend in the future. The quality of crude oil determines the selling price, which is closely related to the density. Therefore, it is worthy for pipeline companies to dig into how to control the mixing proportion of different crude oil to ensure the maximization of crude oil sales benefits. Taking the distribution system of an oil field as an example, this paper first analyzed the profit and loss law of high-quality oil during batch transportation. Then, based on the maximization of crude oil sales benefit, an objective programming model was established to optimize crude oil allocation. Finally, this paper proposes the optimum density limit for crude oil batch transportation by discussing the influence of mixing crude oil density on the supply, profit, and loss. The optimized result of the oil field’s transportation and distribution system shows it can significantly increase the crude oil sales profit when the mixing crude oil density of medium I crude oil is between 868 and 869 kg/m3, and medium II crude oil is about 889 kg/m3. This conclusion has also been verified in the field, and achieved good application results.
