Evaluation Methods and Influencing Factors of Gas Wettability

Introduce ten traditional mature evaluation methods of wettability of the solid surface in the oil/water/solid system systematically; the advantages and disadvantages of gas wettability evaluation by using the frequently used capillary force rise method, contact angle method, and Washburn method; for the features of gas wettability, establish the sessile drop method and the bubble capture method for evaluating the wettability of the solid surface in gas/liquid/solid, and discuss the factors and laws influencing the gas wettability
