Why Sodium Methallyl Sulfonate Can Be Effectively Injected Without Plugging in the Middle and Late Stages of Low-Permeability Reservoirs

In the middle and late stages of low-permeability reservoirs, the pore structure is complex, with narrow throats and strong heterogeneity, making effective water injection and profile control extremely challenging. However, Sodium methallyl sulfonate (SMAS) can still be effectively injected without causing reservoir plugging, which is mainly attributed to its unique Read more

Sodium Methallyl Sulfonate (SMAS) Copolymers Significantly Improve Fluid Loss Control in High‑Temperature Deep‑Well Drilling Fluids

Why Sodium Methallyl Sulfonate (SMAS) Copolymers Significantly Improve Fluid Loss Control in High‑Temperature Deep‑Well Drilling Fluids

In deep‑well drilling fluids under high‑temperature conditions, sodium methallyl sulfonate (SMAS) copolymers significantly enhance fluid loss control primarily through an “adsorption‑hydration” synergistic film‑forming mechanism and the unique chemical stability of the sulfonate group (–SO₃⁻). Mechanism: Synergy between Adsorption and Hydration Stability under High‑Temperature Conditions High temperatures in deep wells severely challenge conventional polymers, Read more
