The effect of parameters on Копытов decreasing development model is analyzed. The method of deciding the development model of Копытов in the early stage of development was put forward to facilitate the initial decision-making. The logVD-logRp plate, the logVD-log (t / c) plate and the logRp-log (t / c) plate of the Копытов decreasing development model were produced. The judgment method, the three-point parabola method and the matching methods of three kinds of plate matching are put forward to develop the middle and late Копытов diminishing development model, which lays the foundation for the development of middle and late prediction. Колытов Decreased Development Model is a fast decay model
