摘要： 绝大多数油藏的油水界面都是倾斜的,倾斜的原因是储集层物性的规律性变化,并非水动力。油气充注也不是油水界面倾斜的主要原因,因为油气充注的速度太小,不足以让油水界面产生较大的倾角。油水界面的平衡时间也不需要太长,因油气充注而导致的油水界面倾斜会在短时间内达到平衡。

Abstract: Most water-oil contacts of reservoirs are usually dipping, which is caused by the regular change of property of reservoir rock, and is not related to the current water-flow underground. Oil and gas pouring to reservoirs is also not the main cause of dipping of contacts, because the pouring rate is not high enough to dip the water-oil contact to certain content. The balancing of water-oil contacts takes quite short time, so the contacts of the most reservoirs are in equilibrium state at present, only a few reservoirs are still in adjusting.

Key words: reservoir, water-oil contact, oil/gas pouring, balance
