Key operation technologies and prospects to product oil pipeline network under market-oriented reform

With the establishment of China Oil & Gas Pipeline Network Corporation, the management mode of "a unified national network" and the "X+1+X" market system are gradually developed for the product oil pipeline network. Meanwhile, the development trend of operation marketization and user diversification brings about great changes and challenges to the market-oriented operation of the product oil pipeline network. Herein, the core issues concerning the layout and resource allocation optimization of the product oil pipeline network system, the collaborative optimization of transportation price and route, and the assessment & allocation mechanism of transportation capacity were summarized focusing on the key technologies for market-oriented operation of product oil pipeline network. Moreover, the progress of research on the relevant technologies at home and abroad was overviewed, and the development direction was pointed out. In the future, the reformation of the product oil pipeline network will be deepened continuously, and the sounder operation mechanism will better promote the open-access, energy saving and carbon emission reduction of the pipeline network. Hence, deep development is recommended for the flexible transportation of clean energy, multi-type network integration of comprehensive three-dimensional transportation and establishment of public information service platform, so as to further improve the operation mechanism of pipeline network, enhance the intensive energy transportation and fair service capability of pipeline network, and thus ensure the nationwide energy supply security.
