Abstract: As a key link for the production and operation of oilfield enterprises,crude oil transportation and distribution system is complex and variable,covering a vast area and involving many stakeholders,through which commercial oil is exported and marketed. It is the primary goal for oil scheduling to optimize oil transportation and marketing allocation patterns,and maximize marketing profit under the premise of ensuring pipeline transportation safety. In this paper,the oil transportation and distribution system of Xinjiang Oilfield is studied,and oil production,supply,marketing and storage are integrated together. By setting up an optimization and allocation system for regional resources and determining performance evaluation factors,simulation model for long-distance oil transportation pipeline operation,mathematical model for oil density and viscosity calculations,and mathematical model for the optimized allocation of multiple stations and storages were built to optimize the flow direction for oil marketing and allocation,oil blending ratio,and the operation patterns of oil transportation stations and pipelines. After optimization,the annual oil marketing benefit has increased by hundreds of millions yuan.
