摘要
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[1]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、Qt)的直线变量组合关系。通过数据分析,利用二元回归[7][8]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。
The methods of automatic curves match and filtration to analyze productivity degradation are provided in the paper.Based on Arps equation experienced degradation curves(exponential degradation、conciliatory degradation、hyperbolic degradation) and actual data of productivity degradation,we use Arps equation experienced degradation curves to deal with the data and find the combinatorial relation of the variables of Q、N_p and Q_t.According to the analysis of data,binary regression method is used to fit curves and confirm the types of degradation curves and find the rule of productivity degradation.At last,we develop a software of degradation rule which will provide theoretical basis for oil fields production.
