Because the most of crude oil has the nature of "three-high" in China and the natural aging of crude oil in the part of oil field, the transmission of crude-oil has reduced, and the oil refining has increased in oil field, Thus the majority of pipelines laid in china are running at a low-flowrate. Analysis of the problems in the running of low-flowrate pipeline: with the temperature drops up, the viscosity increases; the accident of condensate tubes very easily occurs; the turnover point increases; the pressure load of pipeline increases; the supply of heat is shortage, the reliability of equipment is reduced; costs increases and so on. There is proposing the main operation mode to solve the pipeline in low-flowrate, including intermittent transportation, the transportation of mixing light oil, oil and gas batch transportation, the transportation with adding pour point depressant and so on, and has discussed the instability of the running of hot pipeline in the low-flowrate.
