摘　　要：随着水平井大斜度井技术应用规模的快速扩大,水平井中气-水两相流流型识别对生产测井产出剖面解释具有重要的意义。主要开展了基于倾斜及水平条件下大管径气-水两相管流的流型试验研究,意在从井筒内部的流体流动状态入手,研究生产测井测量的3个主要流动参数(总流量、持水率、井斜角)和流型之间的关系。根据试验数据,以这些参数为坐标轴,绘制出了二维和三维流型分析图版,分析了生产测井流动参数与井下流型的关系,用来指导水平井生产测井流型识别;并对生产测井流动参数对流型的影响做了分析。研究结果对正确认识水平井生产测井气-水两相流流型提供了重要依据。With the rapid increase of application of horizontal and high deviation wells,it was of great importance for producing profile interpretation of gas-water two phase-flow pattern recognition in production well logging.A flow pattern diagnosis method was developed for gas-water two-phase flow after the comprehensive mechanistic model was evaluated against the data collected from the gas-water and oil-water two phase-flow simulated experiment,the data included flow pattern,inclination angle,total flow rate and water holdup.Two-dimensional flow pattern maps are plotted with mixture velocity vs.water holdup.Furthermore,three-dimension flow pattern maps are also plotted with mixture velocity and water holdup vs.inclination angle in order to strengthen the common suitability of the pattern map.The results provide an important basis for understanding the distribution of the gas-water two-phase flow during production logging in horizontal wells.
