摘要
分析了目前常用的Arps产量递减法求解递减率D_i和递减指数n的不足,通过对Arps产量递减理论公式的进一步推导,提出用规划求解法求解递减率D_i和递减指数n的方法,扩展了Arps递减的应用范围,可以预测递减指数n<0和n>1时的递减规律。该方法成功在渤海油田应用,具有一定的实用性和可行性。
Based on analysis of the disadvantages of Arps production decline method for solving the decline rate, D1, and the decline index, n, a programming solving method was proposed by deducing the theoretical formula of Arias production decline, which extends the application range of the Arps production decline method. The method can predict the rules of production decline when the decline index n 〈 0 or n 〉 1. The method has been successfully applied in Bohai Oilfield. The application results indicated that the method has a certain practicability and feasibility.
