摘　　要：以南海北部海域X气田1H气井为例,建立了多段水平气井模型,进行试井解释研究。通过对该井实际试井解释的应用效果对比,分析多段水平气井模型相对于常规水平井模型的优势。研究表明,应用多段水平气井模型可对水平气井的有效段数、长度、间隔等参数进行合理解释,解释结果更符合储层实际。Taking 1H well of X gas field in the northern part of the South China Sea as an example,a multi-segment horizontal gas well model is established for well testing interpretation research.The applicational effects of actual well testing interpretation of 1H well are used to compare and analyze the advantages of multi-segment horizontal gas well model over conventional horizontal gas well model.The research shows that the application of a multisegment horizontal gas well model can reasonably explain the parameters including the number of effective segment,length,interval of the horizontal gas well,and the interpretation results are more in line with the real situation of the reservoir.
