“…With the further increase in Ca 2+ concentration, the clay particles are transformed into surface-to-surface connection, which makes the clay flocculate and settle and increase the fluid loss. 35 After adding 1 w/v % psyllium husk, the low concentration of Ca 2+ will promote the adsorption of anionic polymers on the clay surface and prevent the flocculation of clay particles, so the fluid loss will not change much. As the concentration of Ca 2+ increases, the flocculation of clay particles leads to an increase in the fluid loss of the drilling fluid.…”

“…This is because the seed shell powder of plantain is a branched polysaccharide, and its molecular branched chain structure has a large number of hydrophilic groups, which can adsorb a large number of water molecules. Meanwhile, the psyllium husk after water absorption will form a hydration membrane to increase the elasticity of the molecular chain, which is conducive to the formation of compressible mud cake to reduce filtration. , …”

“…This is because after hot rolling, Ca 2+ will cause edge-to-edge bonding and edge-to-surface bonding between the clays, resulting in a three-dimensional structure, resulting in an increase in filter loss. With the further increase in Ca 2+ concentration, the clay particles are transformed into surface-to-surface connection, which makes the clay flocculate and settle and increase the fluid loss .

Aiming at the challenge that environmental protection and high-temperature fluid loss reduction performance of the traditional water-based drilling fluid treatment agent are difficult to balance, our studies added psyllium husk as a high-temperature-resistant and environmentally friendly filtrate reducer to a water-based drilling fluid. The composition, physical and chemical properties, and microstructure of psyllium husk are characterized. Then, the effects of psyllium husk after hot rolling at different temperatures on the rheological properties and fluid loss properties of bentonite-based slurry are evaluated. The results show that the psyllium husk added to the bentonite-based slurry can effectively improve the rheological properties and fluid loss properties of the bentonite-based slurry, and the temperature resistance can reach 160 °C. After hot rolling at 160 °C, adding 1 w/v % psyllium husk can reduce the API fluid loss and high-temperature and high-pressure fluid loss of the bentonite-based slurry by 76.04 and 56.91%, respectively, showing excellent fluid loss reduction performance at high temperatures. The branched structure and uronic acid of psyllium husk can inhibit the degradation of its own molecular structure to a certain extent, which is the fundamental reason why psyllium husk still has excellent fluid loss reduction performance at high temperatures. Psyllium husk is expected to replace some traditional synthetic polymers and be used in environmentally friendly high-temperature-resistant water-based drilling fluids.

In the drilling industry, the demand for environmentally friendly additives with high thermal stability is increasing due to the dual factors of increasing environmental pressure and high-temperature oil layers. However, commonly used non-toxic and biodegradable additives, such as etherified modified starch, cannot withstand temperatures higher than 150 °C. Additionally, natural polymers with better thermal stability obtained through graft modification with sulfonated monomers face challenges in meeting the standards of toxicity and biodegradability. To address these technical problems, a novel graft and crosslink copolymer, St-AA/AM/NVP/MBA (SAANM), was synthesized from corn starch by combining graft modification with a non-sulfonated monomer and cross-linking modification. Laboratory evaluation results confirm that the thermal stability of SAANM in a nitrogen atmosphere was close to 300 ℃, and it exhibits excellent temperature resistance up to 170 °C in bentonite-based mud, while also retaining the non-toxic and biodegradable characteristics of starch. The water-based drilling fluid (WBDF), added with SAANM, demonstrated outstanding rheological properties, fluid loss control performance, and environmental friendliness after aging at 170 °C and being polluted by high concentrations of NaCl or CaCl2. The successful application of SAANM in a high-temperature directional well in an offshore oil field confirms its potential for borehole cleaning and wellbore stability.
