油田注汽蒸汽干度计量技术研究

Research of Steam Dryness Measurement Technology in Oilfield

注蒸汽热采是稠油开发中普遍采用的助采方式,注入蒸汽的流量和干度直接影响油井的采出率,湿蒸汽是一种两相流,湿蒸汽计量存在较大的技术困难。本文对比双差压、单孔板噪音、双涡街等计量技术,经过理论分析和实际应用对比,总结出了多种蒸汽计量技术的特点和适用范围。

Steam injection is a commonly used method in heavy oil development.The flow and dryness of steam injection directly affect the recovery rate of oil wells.Wet steam is a two-phase flow,and there are great technical difficulties in wet steam measurement.This paper compares double differential pressure,single orifice noise,double vortex street metering technology,through theoretical analysis and practical application comparison,summarizes the characteristics and application scope of a variety of steam metering technology。
