摘要： 岩石是亲油、还是亲水,通过实验测量就可以确定。但地下不存在亲油的岩石,实验测量不出地下岩石的亲油特性,只能测量岩石亲水程度的强弱。地下岩石的亲水特性,为油气顺利运移至圈闭提供了保障,也为油藏压力的正常分布提供了保障。若岩石亲油,油气将散失在运移途中,从而无法聚集成藏。若油藏中的岩石亲油,地层压力的分布将出现不可思议的现象。因此,地下没有亲油的岩石,地下的岩石只能亲水。

Abstract: Wettability of rocks can be determined through experimental measurements indoors. However there is no oil-wet rock underground. By experiment, the degree of water-wettability of rocks can only be measured rather than the oil-wet property of rocks. The water-wet property of rocks makes them possible that oil and gas migrate to traps successfully, and the pressure of reservoirs distributes normally. If the rock underground is oil-wet, oil and gas will scatter along the migration way and no hydrocarbon will be accumulated finally. In oil-wet reservoirs, the distribution of formation pressure will appear as incredible phenomenon. It is concluded that there is no oil-wet rock underground, and the rocks underground can only be water-wet in nature.

Key words: rock, reservoir, wettability, oil-wet, water-wet, pressure distribution, oil-gas migration
