摘要

传统的Arps产量递减分析方法要求事先选定递减规律的初始时间、初始产量及初始递减率,事实上这些参数是很难确定的。实际应用时不得不人为地加以臆断而使得此方法带有不确定性.为此提出了产量递减规律的诊断方法。应用诊断曲线很容易确定递减规律的模型参数,克服常规方法的不足。通过选用参考时间、参考产量和参考递减率,使得递减分析方法具有一定的灵活性和优越性、该方法简便、实用。

Abstract

Traditional Arps production decline analysis method requires to determine the initial time, production and decline ratio before analyzing. Owing to the difficulty for determining these factors in actual operation, the results obtained from this method are often cluestionable. This paper presents the diagnosis method for production decline laws, by which it is very easy to determine the model parameters of the production decline laws.Through choosing referential time, production and decline ratio, this method is more flexible, simple and practical than the Arps method in terms of analyzing the production decline.
