摘要
以Arps经验递减曲线方程(指数递减、调和递减、双曲线递减)为理论基础,以五里湾油藏递减期实际生产数据为依据,利用目前常用的递减类型判断方法(图解法、试凑法、曲线位移法、二元回归法、及递减曲线标准图版法)并且结合广义递减曲线标准图版法对产量递减类型进行判断。多种方法相互结合,相互验证,进行综合判断能提高结果的精确度,选择出最佳的递减类型。通过实例计算,说明综合判断法[1,2]计算五里湾油藏递减参数具有较高的可行性。
Based on Arps experience decline curve equation(exponential decline,harmonic decline,hyperbolic decline),with actual production data of Wuliwan reservoir decline period as the basis,and combined with the generalized decline curve standard plate method,types of production decline were judged by using the common decline type judgment method(graphical method,trial and error method,curve displacement method,bivariate regression method,and the decline curve standard plate method).Combining with various methods and mutual authentication can improve the accuracy of comprehensive judgment,and the best decrement type can been chosen.The example calculation shows that the comprehensive judgment method has high feasibility for calculating decline parameters of Wuliwan reservoir.
