摘　　要：为满足我国油田试井分析需要,研发了UST数值试井软件。该软件采用先进的PEBI网格,满足复杂边界、井间干扰及特殊油藏的网格划分需求;能进行油、气、水三相试井解释,正确模拟过泡点现象;具有多层、层间窜流、层间非均匀性的描述能力,支持大地坐标与相位图导入功能;能进行多井模拟,可根据需要选择井模型。结合算例介绍了试井分析的特点,给出了压力降落与压力恢复时的压力导数的典型特征。To meet the needs of China's oil well test analysis,research and development of the UST numerical well test software has been done.The software uses advanced PEBI grid to meet the needs of complex boundary,interference between wells and classified grid for the special reservoir,which can complete job of well test interpretation for three-phase of oil-gas-water,analog phenomenon over bubble point properly,has describing ability for a multi-layer,layer channeling flow,non-uniformity of reservoirs,and support importing function of the phase diagram and the geodetic coordinate,is capable of multi-well simulation according to selected well models.Example is presented with the characteristics of well test analysis,the down off pressure and pressure recovery of the pressure derivative of the typical characteristics are given.
