中石化管道储运分公司所属的鲁宁管线扬子分输站4台口径为150mm的流量计,还有仪金管线石埠桥站2台口径为300mm的流量计,输送的是胜利油田原油。现对流量计在使用中遇到的问题进行总结分析。一、输油系统的工艺状况不同对流量计的影响鲁宁管线原仪征计量站和扬子分输站的输油工艺状况完全不同,鲁宁管线来油先进入仪征站2万立方米储油罐,放置最少24h,然后外输到仪征计量站进行计量装船。原油中的杂质都沉淀在储油罐内,这样原油中的杂质对仪征计量站的体积管、流量计的磨损都降低到最小限度,对原油计量的准确度没有造成不
SINOPEC Pipeline Storage and Transportation Branch belongs to the pipeline pipeline Yangtze Subway 4 sets of diameter of 150mm flow meter, as well as the instrument line Shibuqiao station 2 diameter 300mm flow meter, the delivery of the Shengli Oilfield crude oil. The flowmeter in the use of the problems encountered in the analysis. First, the oil system of the different process conditions on the flowmeter Lu Ning pipeline Yizheng metering station and the Yangtze sub-station of the oil delivery process completely different conditions, Lu Ning pipeline to Yizheng station to enter the first 20,000 cubic meters of oil storage tank , Placed at least 24h, and then exported to Yizheng metering station for metering shipment. Crude oil impurities are precipitated in the storage tank, so that the crude oil impurities on the Yizheng metering station volume tube, flowmeter wear and tear are reduced to a minimum, did not cause the accuracy of the measurement of crude oil
