In this study, a multistage enhanced intelligent gel based on a dynamic network structure was prepared, exhibiting high mechanical strength, strong adhesion, self-healing ability, and long-term stability. First, the gels with and without the addition of Polyaluminium Chloride (PAC) were analyzed using Scanning Electron Microscopy − Energy Dispersive Spectrometer (SEM-EDS) and X-ray Diffraction (XRD) tests. The results showed that with the addition of PAC, the gel structure became more compact, the crosslinked network was more complete, significantly enhancing the mechanical strength of the gel, and promoting the formation of microcrystalline regions within the system, thereby further improving the overall performance of the gel. Subsequently, the thermal resistance and long-term stability of the gel were evaluated. The results indicated that the maximum thermal resistance of the gel system reached 237.9 °C, and it maintained good stability after aging at 140 °C for 90 days. In terms of mechanical strength, adhesion properties, and self-healing ability, the results showed that the maximum compressive strength of the gel reached 545.2 kPa, the storage modulus (G’) was 50.1 kPa, and the loss modulus (G’’) was 18.1 kPa. The mechanical strength of the healed gel was able to recover to more than 60 % of its original state after damage. Adhesion tests showed that the gel exhibited excellent adhesion properties to various materials, particularly with an adhesion strength of 63.7 kPa to the sand column. Finally, the results of core displacement experiments show that the gel has a breakthrough pressure of up to 9 MPa and a residual resistance factor of 796, and at the same time, the reservoir damage rate is less than 15 %, demonstrating excellent water shutdown capability and low damage characteristics for cores with different permeabilities. Therefore, this new type of smart gel provides a new technical method for water shutdown and oil recovery enhancement in oilfields.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"428 ","pages":"Article 127586"},"PeriodicalIF":5.3,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the current production process faces challenges including the inability to simultaneously extract amygdalin and oil, and the risk of toxicity due to amygdalin contamination in the oil. A novel, green and efficient ultrasonication-assisted extraction (UAE) method based on a natural deep eutectic solvent (NADES) composed of choline chloride-lactic acid (CC-LA) was established for simultaneous extraction of amygdalin and oil from BAK for the first time. Under optimizing conditions of a liquid-to-solid ratio of 18 mL/g, ultrasonic power of 420 W, temperature of 42 °C, and extraction time of 32 min, the highest yields of amygdalin and oil were achieved at 10.22 ± 0.04 % and 45.64 ± 0.24 %, respectively. The yield of amygdalin in UAE based on CC-LA was twice and nineteen times that of methanol (90 %, v/v) and water, respectively. Meanwhile, the yield of oil obtained by this new method was comparable to that by organic solvent extraction methods. The fatty acid composition of oil obtained by this method was consistent with that by conventional extraction methods.
