摘　　要：在原油管输交接计量过程中,如何持续监测原油含水率,并确保测量数据的准确性是一项技术难题.根据原油取样代表性要求和管道截面含水率不均匀的情况,研发了毂辐式多点油品采样器,介绍了该采样器的结构和工作原理,通过实际应用表明,该采样器可均匀获取输油管道截面各位置的原油试样,所收集数据能够客观反映流体分布状态,值得推广应用.In the process of crude oil pipeline transfer measurement,how to continuously monitor the water content of crude oil,and ensure that the accuracy of measuring data is a technical problem.According to the representative requirements of crude oil sampling and the uneven water content of the pipe cross section,a hub-spoke multipoint oil sampler is developed,and its structure and working principle are introduced.The practical application shows that the sampler can evenly obtain crude oil samples at all positions of the cross section of the oil pipeline,and the collected data can objectively reflect the fluid distribution state,which is worth popularizing and applying.
