It was found that the contact angle of the ,fracturing fluid, is the smallest and its wetting height is also the smallest in the three improving fluids, which is in accord with the results of the wetting model developed in the above section. The effect of improving ,fluid, wettability on gas flow can be explained as in Fig. 21.

Dynamic Variation of Water Saturation and Its Effect on ...

Dynamic variation of water saturation near a wellbore may cause serious aqueous phase trapping (APT) damage in gas well production, especially in partly water-saturated tight sandstone gas reservoirs. In this paper, a prognosis model was deduced and used to characterize the dynamic variation of water saturation. In addition, experimental evaluations of APT damage were conducted to reveal the ...
