摘要
通过对J.J.Arps方程的推导,提出了油气藏产量递减曲线分析的最佳拟合法。用该法可直接求出递减指数N、初始递减率D1及油气递减前的稳定产量Qi,避免了使用试差法的大量运算过程,大大提高了油气藏工程中指标预测的精度。
Through deriving J. J. Arps equation,a optimun fitting of production decline curve analysis of oil and gas reservoirs is presented in this paper. The decline exponent N,original decline rate D_i and stable production Q_i before oil and gas decline can be directly obtained by this method,greatly simplifying cal- culation processes in comparison with trial and error method and raising the precision in index predic- tion of reservoir engineering.
