摘要
系统阐述了海洋油气开发中经常遇到的多相流动问题，如确定油藏量和油藏的分布与变化规律的多相渗流问题，油井中产液的变质量多相流问题，油井和立管的竖直与倾斜管多相流问题，油气水在管线中的水力与热力规律问题，输送管道系统提升泵和增压泵的性能、分离器的效率，混相流量的计量等问题。文中还介绍了中国科学院力学研究所在油气水多相增压、多相计量、多相分离、稠油除砂、倾斜井多相流态等方面的研究工作。重点阐述了集离心、膨胀、重力分离原理为一体的新型油气水高效分离器的性能和特点，以及用γ射线硬场层析成像方式来实现油气水混相流量测量方案。
Multiphase flow problems involved in offshore gas and oil development are described in this paper, such as the multiphase flow in porous media in determining the oil reserves, the distribution and variation of oil deposit; the multiphase flow with changeable flux in horizontal, vertical and inclined oil wells; hydrodynamic and thermodynamic properties of oil/gas/water multiphase flows in pipelines; and multiphase bumping, multiphase metering and multiphase separating in transportation pipelines. The research developments achieved in oil/gas/water multiphase pumping, multiphase metering, multiphase separating, dense oil desanding, and multiphase well logging are also presented in the paper.
