本文讨论了试井分析计算机自动拟合的理论问题及实现过程。针对人机交互式试井解释误差大、速度慢、结果不唯一等缺点,按另一思路,将图形拟合归结为数学物理反问题来求解,使理论值与实际值的平方和误差最小。同时提出了一套切实可行的算法,为进一步研制试井分析专家系统软件打下了基础。 This paper discusses the theoretical problems and implementation process of automated well testing computer simulation. According to the shortcoming of human-computer interactive well test interpretation errors such as large error, slow speed and non-unique result, the graphic fitting can be attributed to the inverse problem of mathematical physics to solve the square error of the theoretical value and the actual value. At the same time, a set of practical algorithms is put forward, laying the foundation for the further development of well testing analysis expert system software.
