摘要: 本文基于Arps的双曲绕递减,提供了一个新型递减曲线方法,同时,对于广泛庄用于我国油田的修正的KomAroB 经验公式作了推导,它是当递减指数n=1/2时Arps公式的特例。新型递减曲线方程是一个直线方程,它的求解不需要试差法或曲线位移法。

Abstract: A new type cquation of decline curve is derived in this paper, based on the application of Arps's hyperbolic decline. Also, the modified Kopatov' s empirical formula, which has been widely used in at home, is derived and suggest that it is a specific case of Arps's hyperbolic decline when the decline exponent n is 1/2. The new type equationis a straight line equation and its solution can be easily given without using the trial and error method and curve shifting method.
