钻井布局的数学模型

The mathematics model of artesian well overall arrangment

采用相对运动理论 ,用旧井坐标的移动或旋转来代替网格的移动或旋转 ,寻找最优的钻井布局方案 ,并用定长搜索法搜索求得最大的可以利用的旧井点数 .在搜索的过程中 ,用小数法判断 .并给出一个小数定理 ,求出了 n个旧井点均可利用的充分条件 .

For hunting the optimal strategies of artesian well overall arrangement,comparative movement method,using shifting and circumrotation of original wellscoordinate in stead of that of gridding was adopted. Meanwhile,the stationary searching method was adopted and the most available ordinary well numbers were got.In process of searching a decimal fraction principle to judge the answers was introduced.
