本文提供了应用计算机自动拟合曲线法和筛选法进行产能衰减曲线分析,以 Arps经验递减曲线方程既(指数递减、调和递减、双曲线递减)为理论基础,以油田产能衰减的实际数据为依据,用Arps经验递减曲线方程进行处理,找出(Q、Np、Q1)的直线变量组合关系。通过数据分析,利用二元回归对曲线进行拟合,确定递减曲线类型、找出产能递减的规律,编制递减规律软件,为油田的开采提供一定的理论依据。 This paper provides a method of automatically decaying curves of production capacity using computer automatic fitting curve method and screening method. Taking Arps empirical decreasing curve equation as the theoretical basis (exponential decreasing, harmonic decreasing, hyperbolic decreasing) as the basis, the actual data of oil field production decay , Arps empirical decline curve equation processing, find (Q, Np, Q1) linear combination of variables. Through data analysis, the regression curve was fitted by binary regression, the type of decreasing curve was determined, the law of diminishing productivity was found, and the software of decreasing regularity was compiled to provide some theoretical basis for oil field exploitation.
