Witryna5 lut 2024 · In addition, the imbibition of fluid with additives was also different in various clay content shale samples. In the high clay content sample, the fluid with 0.07% friction reducer has a greater imbibed volume than the fluid with KCl or KCl substitute (choline chloride, magnesium chloride, and tetramethyl ammonium chloride). WitrynaThe original water distribution characteristic plays an important role in the fracturing liquid retention in actual tight reservoirs. In this paper, an analytical model was proposed to characterize the water distribution and its effect on the spontaneous imbibition, based on the capillary tube model and fractal theory. Furthermore, the effect of the water film …

Witryna7 kwi 2024 · One example of imbibition in nature is the absorption of water by hydrophilic colloids. Protein has a great barrier potential, so proteinaceous pea seeds … Witryna6 kwi 2024 · In other words, spontaneous imbibition is not significantly affected when the viscous pressure-driven flow velocity is less than 10 times the spontaneous imbibition velocity. The maximum water saturation is 0.22, which is consistent with the positive maximum water saturation in the capillary pressure curves (c.f. Fig. 9 ). how birthdays work in korea

Witryna4 sty 2024 · Imbibition is an important mechanism to improve the recovery factor (RF) of a tight oil reservoir. Accurately evaluating the oil production capacity of tight oil reservoirs by imbibition is of great significance for the formulation of oilfield production plans and productivity prediction. However, there is currently no unified regulation on the … Witryna3 paź 2012 · Then, when the imbibition front has reached halfway the sample, the temperature is lowered below T λ. The dynamics of the liquid invasion changes then remarkably compared to the normal liquid phase. First, a line moves rapidly from the imbibition front to the top of the sample in less than 10 s (only visible on the … Witryna29 sty 2024 · Most rock in a natural reservoir is mixed-wetted, but most studies on the pore-scale imbibition process only focused on the water-wetted rock. This paper adopts two mixed-wetted core samples for microspontaneous imbibition experiment, micro-CT scanning, and nuclear magnetic resonance (NMR) test. how birth year influences politics
