用富含沥青质的单家寺原油制备了天然油湿岩心,与通常用硅油处理的岩心相比较,该岩心的油湿特性更接近油藏岩石.在相同实验条件下获得的油湿程度较高,油湿持久性好,处理后的岩心渗透率基本不受影响.评价了各种因素对处理效果的影响.其中老化温度的影响较为明显,随温度升高,岩样的油湿性增强.
The natural oil wet core was prepared from the asphaltene-rich single-sourced crude oil, which was closer to reservoir rocks than the one usually treated with silicone oil.The degree of oil-wet under the same experimental conditions High oil and wet durability, and the treated core permeability was basically unaffected.Effects of various factors on the treatment effect were evaluated.Among them, the influence of aging temperature was obvious, with the increase of temperature, the oil wettability of rock samples was enhanced.
