The wettability of carbon black to water is improved and the dispersing stability is enhanced. 親水性改性后的炭黑對水的潤濕性增強，在水中分散更穩定。
The differences of impacts of wettability on electric properties are caused by the differences of reservoir connectivity and heterogeneity at low water saturation. 在低含水飽和度下，潤濕性對電性影響的差異可歸因於儲層連通性和均質性的不同。
Another end for the hydroxyl and the carboxyl group, has the water affinity. 另一端為羥基和羧基，具有親水性。
The wettability of carbon black to water is improved and the dispersing stability is enhanced. 親水性改性后的炭黑對水的潤濕性增強，在水中分散更穩定。
