| 摘 要： | 将遗传算法用于试井解释，正问题采用数值的方法求出，并对整段压力曲线进行拟合。采用多次循环搜索的办法，有效避免了局部极小问题；采用隐性二进制编码法，有效提高了速度，减小了存储。该算法迭代次数较少，收敛较快，精度较高，解释结果可直接满足需要，也可作为线化反演的可靠初值，具有很强的实用性。

| Abstract: | The application of genetic algorithm on well test analysis is discussed.The multiple searching method is used for avoiding local extreme value problem and the implicit binary coding method is used to increase calculating velocity and reduce the storage.The algorithm is quick for auto-matching and high exact in result.The analysis result can also be combined with linear inverse method and used as the initial value of the latter method which ca be easily used in well test interpretation in the oilfield. |
