Though logging datas and geological datas can be used to judge the position of formation water and water yield before gas drilling starte to drill. 尽管在气体钻井开钻之前，可以利用邻井测井资料和地质资料预测出水层位置和出水量，但这并不能够预测出所有的出水层。
Distribution of well drilling can be summarized as the problem of decreasing the number of new wells for lowering the cost by using the geological material under some restrains. 本文对钻井布局问题提出了有效的算法，钻井布局可以归结为在一定约束条件下利用旧井的地质资料来减少新井的钻探数量，以节省钻探费用的问题。
