Key Technical Issues and Solutions Towards Mixed Product Oil Transfer Supervision System

In order to satisfy the functional and precision requirements of mixed product oil transfer supervision system, this paper proposed a combined solution to calculate the batches of product oil by integratethe method of pipeline flow interface and the method of per-station density correction together. Based on the introduction of on-site meter value features of product oil pipeline, this paper discussed the calculation of batch mileage, the algorithm of per-station density correction, features of flow data and the calculation and correction of equivalent length of pipeline in the R ＆D process of the mixed product oil transfer supervision system. At present, this solution has been used on Lanzhou- Chengdu-Chongqing Product Oil Pipeline and the Western Product Oil Pipeline.
