水平管中油气水三相流动实验研究

Experimental Studies of Three-phase Gas-Oil-Water Flow in Horizontal Pipes

长距离油气水三相流管道混输技术,已经成功应用于海洋油田的开发,目前正引入沙漠、滩涂和极地油田的开发。混输技术研究的重要内容是油气水三相流动的规律,包括流动形态、压降和持液率的规律,其成果对多相流混输系统的设计和运行非常重要。综述了90年代以来国外开展水平管中油气水三相流动研究的情况。由于三相流远比两相流复杂,因此研究工作大多是在借鉴两相流成果的基础上进行的,取得了一些有价值的结果,为进一步深入研究奠定了基础。针对国内外的此项研究工作现状,提出了继续开展研究工作的几点建议。

The technology of long distance oil-gas-water mixted transportation,which has been successfully applied in onshore oilfield development,is applicable as well in the oilfields in desert and beach. The focus of the research includes the law of flow pattern,pressure loss and liquid holdup of the three-phase oil-gas-water flow in horizontal pipes,which is very important to multiphase pipeline transportation. The paper out-lights the above research activities by foreign countries, which are carried out by means of the achievements made in the studies on two-phase flow. Some suggestions are given for the further study on the three-phase gas-oil-water flow in horizontal pipes.,
