2、Architecture and Civil Engineering, Daqing Petroleum Institute, Daqing 163318, China Abstract At present, with deeply exploitation of the oil eld in the eastern land of China, the water-cut of most oil wells exceeds by 85%,and some have even reached 95%.The ow pattern study on oil-gas-water three-ph

3、ase ow is the basis for determining mixed transportation limits with super high water-cut, researching of hydro-thermal calculation method and scientic operation management of gathering and transferring system. We developed a certain set of test device in Daqing oil eld with a series of experiments.

4、 1360group of oil-gas-water three-phase ow pattern photographs and the corresponding ow parameters have been acquired. Five ow patterns are summarized in horizontal circular gathering and transferring pipeline for the rst time. Including stratied ow, three-layer dis-turbed ow, wave surging ow, gas b

5、ombs mixing ow and complete mixing ow. We gave the range of corresponding parameters to each ow pattern, and explained the typical character of each ow pattern.
