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 imple-mentation.Due to the complexity of the mineral composition and the diversity of the fluid composition in the under-ground oil and gas reservoir,there is no uniform standard for measuring the wettability of reservoir rock,and the se-lection 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.
