As global oil and gas exploration gradually shifts toward deeper ultradeep reservoirs, the performance of fluid loss control additives in high-temperature high-salinity environments faces significant challenges. In this study, a agent, DMAPAN, suitable for conditions, was synthesized using N,N-dimethylacrylamide (NNDMA), 2-acrylamido-2-methylpropanesulfonic acid (AMPS), maleic anhydride (MA), N-vinylpyrrolidone (NVP) as monomers via aqueous solution polymerization. Structural characterization testing showed that DMAPAN exhibits good thermal stability significantly reduces at 230 °C. It also demonstrates excellent resistance to high temperature salinity, being able withstand 20% NaCl 2% CaCl2. Mechanistic analysis reveals clay particle size, forms spatial network structure, enhances Zeta potential, thereby improving drilling reducing loss. This study provides theoretical support practical guidance optimizing deep-well fluids.

Diamine-Crosslinked and Blended Polyimide Membranes: An Emerging Strategy in Enhancing H2/CO2 Separation

Polymers, Год журнала: 2025, Номер 17(5), С. 615 - 615

Опубликована: Фев. 25, 2025

The increasing demand for high-purity hydrogen (H2) as renewable energy sources is driving advancements in membrane technology, which essential achieving efficient gas separation. Polyimide (PI) membranes have become an emerging option H2/CO2 separation due to its excellent thermal stability and under harsh conditions. However, the neat PI suffers performance loss CO2 plasticization effect encountered trade-off limit between permeability selectivity. Therefore, modification by crosslinking blending emerged a recent strategy enhance membrane's properties. This paper provides: (1) An overview of possible method do membranes, including advantages challenges types; (2) As most popular membrane, their roles enhancing properties improved are discussed; (3) critical parameters processes also clarified optimal purification process; (4) future outlook using technology discussed, aiming provide commercialization Thus, this review could guidelines readers implement changes that significantly features H2 production.
