| 摘 要： | 文章给出了求解约束最优化问题的一个算法。其要点是分别采用适当的步长,轮流地对目标函数和约束标志函数进行下降迭代计算。通过计算典型例子并与混合罚函数法等一系列算法作了对比,表明计算结果至少有五位有效数字相同。同时,还介绍了该算法在钻井工程优化设计中优选钻进参数的应用。实例计算证明,该算法具有程序简单,使用方便等优点,计算结果能满足工程设计要求。

| Abstract: | An algorithm is proposed for solving constrained optimization problems in drilling parameter optimization. Its main points are that iterative computations of minimizing the objective function and the constrained symbol function are, in turn, done with adopting suitable sizes. Typical examples have been computed with the algorithm and its results are compared with those from SUMT method and other methods showing no difference. Also, an application of the algorithm is described for optimizing drilling parameters in drilling engineering plan. It shows that the algorithm has many advantages, such as programming easily, being convenient to use etc., and its results can satisfy the needs of drilling engineering plan. |
