Development and performance evaluation of macropore intelligent plugging hydrogels.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Polymer hydrogels are the optimal hydrogels for water channeling control applications, and water-dominant channels in deep reservoirs are often blocked by them.A dual-network hydrogel system (DN-Gel) is innovatively proposed in this study. A chemical crosslinking network (ACL-HG) is constructed via glycidyl methacrylate (GMA), poly(ethylene glycol) methyl ether methacrylate (PEGMA), and dopamine methacrylamide (DMA), and is composited with a physical crosslinking network (GQDs-Gel) of functionalized graphene quantum dots (GQDs-GX)/ascorbic acid. A dense dual-network structure is formed through the synergistic effect of Michael addition reaction and hydrogen bonding.FTIR and SEM characterization results show that DN-Gel possesses both the functional group characteristics of the chemical crosslinking network and the nano-reinforcement effect of the physical crosslinking network, and its cross-sectional pore structure is significantly denser than that of single-network hydrogels.Under the optimal ratio and concentration, the viscosity reduction rates of DN-Gel both before and after three shearing cycles within 56 days are maintained below 20%.Under high-temperature and high-salinity conditions, a mass retention rate of over 80.6% is achieved after 60 days.Core simulation results show that DN-Gel has a breakthrough pressure gradient of 129.21 MPa/m and a permeability change rate as high as 99.21%, which is significantly improved compared with traditional plugging agents.This study provides a new material design method and theoretical basis for the green and efficient plugging of sandstone reservoirs.
