科学技术的不断发展，加速了人们对海洋油气勘探向更深的领域迈进。为了实时监测油井井流的变化，以便更好地优化对油藏的开发，水下多相流量计得到了越来越多的应用。概述了目前常见的水下多相流量计的基本测量原理，研究了多相流量计在深水油气田开发应用的影响因素，包括量程、安装位置、通讯结构等，给出了各种不同方案的可能性，对多相流量计在深水油气田开发工程中的应用具有一定的指导意义。

The remarkable development of science and technology speeds up the development of the deeper oil and gas field offshore via subsea production system. In order to optimize the reservoir, the well fluid to be monitored and measured to get enough information transmitted to the topside being processed and analysis. Recent years there are more and more subsea multiphase flow meters installed and being in operation. The principles of multiphase flow measurement are introduced and other factors relevant to the measurement scope, installation location and the communication are discussed. The feasibility of cases is also presented and it is helpful for the selection of subsea multiphase flow meters installation.
