摘要
储集岩的润湿性对孔隙中流体的分布与流动至关重要,关系到油气田提高采收率措施的选择及其实施效果,由于地下油气储层中矿物成分复杂、流体组成多样,目前尚无统一的储层岩石润湿性测量标准,根据油藏的具体条件选择合适的润湿性测量方法对石油开采至关重要。基于此,从物理实验与数值模拟两方面详细讨论了国内外目前使用较广且最新的测量岩石润湿性的方法,针对这些方法的原理、优缺点及适用条件进行总结,并对润湿性测量方法进行了展望。该研究有助于优选适用的润湿性测量方法,可为提高储层中岩石润湿性表征的准确性提供借鉴。
The wettability of the reservoir rock is crucial to the distribution and flow of fluids in the pore,which is related to the selection of measures to improve the recovery rate of oil and gas fields and the effect of their implementation.Due to the complexity of the mineral composition and the diversity of the fluid composition in the underground oil and gas reservoir,there is no uniform standard for measuring the wettability of reservoir rock,and the selection of a suitable wettability measurement method according to the specific conditions of the reservoir is crucial to the oil production.Based on this,the most recent and widely used methods for rock wettability measurement at home and abroad were discussed in details in terms of physical experiments and numerical simulations,and the principles,advantages and disadvantages,and applicable conditions of these methods were summarized,and an outlook of the wettability measurement methods was also given.The study helps to select the applicable wettability measurement methods,which can provide a reference for improving the accuracy of rock wettability characterization in reservoirs.
