The new algorithm and its corresponding software we developed has been not only validated in several horizontal wells , but also show their advantages such as shorter length of trajectory designed , more accuracy of target hitting and less time - consuming comparison with present conventional methods . the practical trajectory often deviates the optimal trajectory of provisional design in practical application of horizontal wells . for this reason we propose an optimal control model for designing 3 - dimension horizontal wells with deviation
将它用于多口水平井的实际生产中，表明了本文给出的模型、算法及软件的正确性与有效性，与原有算法和软件相比，本文提出并实现了均匀设计与改进的hooke - jeeves直接搜索法相结合的优化算法，该算法计算时间大大减少，计算精度高，并且能够得到多个最优解。
