In this paper, the problem of using the old wells is reduced to the 0-1 programming problem, and the objective function is established. The principle of mapping is put forward and the location of the old wells is mapped into a unit grid, which greatly simplifies the solution of the model. Principle and exhaustive method, the available problems under the condition of directional constraint are solved, and the available points under the condition of non-directional constraint are transformed and extended to six points, and the available points are solved. Conditions are given three kinds of special cases of the decision method is proposed in the vertical bisector approach
