【Abstract】 The problem of overall arrangement in drilling well is discussed. The problem is about how to use existing wells as many as possible and to drill new wells as few as possible in order to save money. Some arithmetics to be used to solve the problem are given. The sufficient and essential conditions by which to use all of the existing wells are obtained. The computation shows that the arithmetic is effective.更多还原
