摘要
本文用汇源积分等方法求得了圆形封闭油藏水平井单井不定常渗流之Laplace空间井底定压解式,通过Duhamel原理导出水平井单井产量递减公式,用数值反演方法计算了主要参数影响曲线。应用产量递减曲线可以预测水平井在未来某一时间的产量及最终采收率,文中用算例说明了这一应用的具体步骤。
In circular reservoirs, an analytical solution is presented for a horizontal well at constant bottomhole pressure by means of both integrated sources and integral transforms. Then rate decline formulas are deduced according to the Duhamel theorem as well as figured using the Laplace numerical inversion. Concrete methods of the decline applications, illustrated by an example in the paper, can be employed to obtain the horizontal well production forecast.
