摘　　要：对于复杂边界、多变的非均质性油气藏及多相流试井等问题,利用以解析法为基础的常规试井分析方法无法得到工程上所要求的精度,必须应用数值试井分析方法。通过对数值试井方法的调研分析,系统总结了数值试井方法在理论研究和软硬件开发应用2个方面的研究进展。介绍了关于数值试井的主要研究内容,包括参数拟合方法、网格剖分技术、数值模拟的精度控制以及目标参数求解。展望了数值试井技术在地质与采油及油藏工程2个方向上的发展趋势,对于进一步研究数值试井方法具有一定的指导意义。Conventional well test analysis techniques currently developed and implemented have been feasible and simple for the well test designing and analysis on homogeneous and single-phase fluid reservoir,however, the current conventional well testing methods are not feasible for the complex,high variable heterogeneous and multi-phase fluid reservoir due to the phase changes and too many reservoir conditions that should be resolved. The utilization of numerical methods to solve complex well-test problems can not only broaden the content of well test analysis,but also provide a new way for well test analysis solution of multiphase flow. Therefore,the proposed new well test analysis methods are numerical well test analysis. The research progress of the numerical well test method is described respectively with respect to two aspects, theoretical study and development and application of software and hardware. Meanwhile,the main research contents of numerical well test were introduced from four aspects of the parameter, that is,fitting method, mesh generation technology, the control of numerical simulation accuracy and solving of target parameters. Finally, the trends of the numerical well testing technology are proposed according to the present numerical well test study.
