摘要
Копытов(卡彼托夫)的经验公式,是油藏工程的一个有用的方法。它可以用于确定油气田的可采储量和采收率,同时,也能用于预测油气田的未来产量变化。本文利用递减曲线分析的方法,推导了卡彼托夫的经验公式,并表明他的经验公式是本文推导结果的一个特例(当 t_o=0,n=2和 c=0时)。对卡彼托夫经验公式的应用条件作了讨论。
Kopatov's empirical formula is avery useful method in reservoir engineering. It can be used to estimate recoverable reserves and recovery efficiency of an oil/ gas reservoir.At the same time,it can also be used to predict future behavior of oil and gas reservoir. A more general empirical formula is derived in this paper using the method of the decline curve analysis and indicates that Kopatov's empirical formula is a special case of the expression derived in of this paper in case that t(?)=0,n=2 and c=0.The conditions for the application of Kopatov's empirical formula are discussed in this paper.
