摘要
针对目前油气田产量递减分析中通常要求已知递减初期产量且递减指数在［０，１］范围内的情况，提出了一种确定油田产量递减规律的最优化方法。在反映油气田产量递减规律的累积产量与瞬时产量关系式求解过程中，引入了最优化理论，能同时确定递减初期产量、初始递减率及递减指数，避免因递减初期产量选取正确与否对预测结果的影响，而且适用于递减指数在［０，１］范围内以及大于１或小于０的情况。可用于油田产量递减规律的分析和预测。还进行了实例分析，并与文献中的计算结果进行对比。
In the analysis of production decline,it is usually necessary to know the initial decline production and the decline index value varying from 0 to 1. An optimum method for analysing production decline is given for this purpose.The optimum theory is adopted in the process of finding the solution to the correlation of accumulated production vs.production,which gives the production decline performance.With this method, the initial decline production, the initial decline rate and the decline index can be determined simultaneously, and the results are not affected by the initial decline production, and the decline index can vary from 0 to 1 or higher than 1 or lower than 0.As a simple and applicable method,it can be used in analysis and prediction for production decline.
