摘　　要：在井间示踪剂测试资料的半定量-定量化解释方法中,解析方法和数值方法均存在一定的缺点。在总结前人研究成果的基础上,完善了半解析方法的解释理论和机理,建立了示踪剂测试半解析方法体系数学模型。克服了数值方法工作量大、计算速度和精度受网格方向性和步长大小控制等缺点,解决了解析方法无法考虑实际井网的非均质性和井间复杂的连通对应关系等问题。研制了半解析方法体系示踪剂测试解释软件,形成了一套实用可靠的示踪剂测试解释方法,在新疆上乌尔禾组油田矿场测试应用中,取得了较好的效果。There are some defects in the analytical and numerical methods for the semi-quantitative and quantitative interpretation of the well-to-well tracer test data. On the basis of the former study results,the theory and mechanism of semi-analytical interpretation were improved,and a semi-analytical mathematical model for tracer test system was developed. This model can overcome the defects of numerical and analytical methods. This model has advantage of saving time,and the calculation speed and precision were not controlled by the grid direction and grid size. The heterogeneity and the corresponding connectivity between wells could be taken into account in the semi-analytical mathematical model. On the basis of the mathematical model, the software for the semi-analytical tracer test system was developed. A set of practicable and reliable systematic methods was presented. This method got a satisfying result in the field tracer test of Shangwuerhe Oilfield in Xingjiang area.
