湿饱和蒸汽两相流的测量与应用

两相流湿饱和蒸汽的测量是稠油开发注汽过程中的重要环节，两相流体的状态复杂多变，目前理论不完善，给两相流测量造成一定困难。在实际应用中，采用高温高压涡街流量计，同时进行干度定值补偿及温度在线补偿，配备旋转式整流装置。使用微处理器对信号进行采集处理，输出标准流量信号和通信信号。结合现场情况，采用太阳能供电和GPRS数据远程监控系统，不用人工方式就可在现场抄录数据，达到定时、定量、灵活控制注汽的要求，为科学、高效进行稠油开发提供保障。

Measurement and Application of Two Phases Flow of Wet Saturated Steam

Two phases flow of wet saturated steam measurement is a important connection in development of heavy oil and steam injection process,two phases flow mode is complex and changeable,and the theory is not perfect nowadays,it is very difficult to measure two phases flow.In actual application,high-temperature and high-pressure vortex shedding flow meter is adopted,dry degree value compensation and temperature on-line compensation are simultaneously conducted,rotating rectifier is equipped,and microprocessor is used for signal collection and processing,output of standard flow signal and communication signal.Combining with the actual situation,and by using solar energy to supply power and GPRS data remote monitoring system to realize on-site excerpting data without manpower,and to achieve the requirements of timing,quantitative,flexible control steam injection system.It will provide the guarantee for scientific and efficient development of heavy oil.
