摘　　要：研究了利用生产测井资料识别开发中后期水平气井内气水两相流型的方法。建立了与井下生产情况相似的模拟流动环路。用包括新型CAT仪器在内的生产测井仪器串,对不同流动条件下的气水两相混合流动进行仪器测量和关井模拟,观测并划分出了实验流型。利用实验数据绘制的图版,反映了流动参数与井下流型的关系,可辅助识别流型;CAT流型成像与实验流型的对比证明,CAT仪器能够识别开发中后期水平井水平段内气水两相流型,非水平段内的流型还需综合流动参数加以识别。Studied are the methods to identify the gas-water flow pattern in horizontal gas well during middle or late period of its production phase based on production logging data. A flow- loop is established to simulate the downhole mixture flow. Production log tool-string, including CAT （Capacitance Array Tool） is used to measure a series of mixed gas-water two-phase flow, meanwhile the experimental flow patterns are investigated and classified before shutqn simulation is carried out in every situation. The experimental charts illustrating the relation between flow parameters and downhole flow patterns, could be used to aid flow pattern identification. Accord- ing to the comparison between CATView images and photography records of flow patterns, gas- water flow patterns in horizontal or near horizontal wellbore intervals could be identified by CAT, while flow patterns occurred in those wellbore intervals in non-deviated horizontal wells should be identified by flow parameters and CATView images comprehensively.
