第二节势的叠加原理 The line absorbing fluid from formation is called line sink The line sink is equivalent to production well 线源向地层供给液体的点相当于注入井 The line supplying fluid into formation is called line source The line source is equivalent to injection well 线汇(源)的强度单位有效厚度的油层的产量或 注入量q,规定线汇的强度为负,线源的强度为正。 The production or injection of oil layer of unit effective thickness q is called the intensity of line sink(source). It is set that the intensity of line sink is negative and that of line source is positive 对于水平等厚地层,只需讨论它的一个水平截面就够了,此时线汇 (源)就变成点汇(源)。今后对线汇(源)和点汇(源)不加区分。 本章中为行文简洁,一律假设地层厚度h=1
