中文摘要：

随着大庆油田开采的不断深入，油田很多集油环已出现堵塞问题，严重影响油田的安全生产。采用理论计算和现场试验结合的办法，应用多相流、热能工程、自动控制等技术，对油田集油环的运行状态进行研究，研究的截流诊断评价指标，能够确定集油环管道是否堵塞。

英文摘要：

With the continuous deepening of exploitation of oil fields, the problems that many oil-gather-rings have been blocking seriously affect the safety of oil production system.In this paper, theoretical calculations and field test are combined,the technology of multiphase flow,thermal engineering,automation,commtmications engineering, surveying and so on are used in the study of the running of oil-gather-ring, and the results show that： the evaluation indicators can determine whether the oil-gather-ring are clogging.
