摘要: 基于Arps的递减方程,本文研制了一个用于产量递减分析的无因次累积产量和无因次时间的新型典型曲线。由实际资料拟合典型曲线,可以确定递减指数(n)、初始递减率(Di)和初始产量(Qi)。此典型曲线的可靠性,已被油井的生产资料所验证。

Abstract: New type cuIves of dimensionless cumulative prođuction versus dimensionlexs time for production declinc analysis are developed based on Arps’ decline equation. Decline index(n), initial decline rate (Di) and initial production (Qi) can be obtained by macthing field data with the type curves. The reliability of the type curves has been confirmed by well production data.

Key words: production declinc, Decline curves, Decline index, Decline rate, Initial productjon
