With deep and ultra-deep drilling engineering, silane coupling agent KH-570 was used to modify the surface of nanolaponite, acrylamide (AM), 2-acrylamido-2-methylpropanesulfonic acid (AMPS), N-vinylpyrrolidone (NVP), dimethyldiallylammonium chloride (DMDAAC) were selected as monomers. A new fluid loss agent, YH-1, synthesized by aqueous solution polymerization, copolymer characterized infrared spectroscopy, nuclear magnetic resonance hydrogen TEM, molecular weight analysis, thermal stability analysis. The results show that product is consistent with structure design goal. modified nanolaponite successfully introduced relatively uniformly distributed in filtrate reducer, distribution wide. After hot rolling at 240 °C for 16 h, it can still maintain good apparent viscosity, plastic dynamic ratio. When addition amount 1.5 wt %, viscosity be maintained 40 mPa·s, its high-temperature high-pressure (HTHP) filtration lowest compared domestic foreign commercial filter reducers. Through particle size distribution, scanning electron microscopy, zeta potential cake formed after adding YH-1 smooth shiny, hydration film bentonite particles thicker. adsorption group adsorbed on particles, ionizes a large number negatively charged groups, which increases thickness particles. enhances plugging effect mud cake, improves impermeability performance.

Water-based drilling fluids are prone to contamination by high temperatures and salt, resulting in a deteriorated filtration performance of the fluids, posing significant threat safety operations. This study utilized N,N-dimethylacrylamide (DMAA), 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), dimethyldiallylammonium chloride (DMDAAC), N-vinylpyrrolidone (NVP), nanomaterials (nano-SiO2 nanolaponite) prepare polymer nanocomposite NP-3 as filtratef reducer for fluids. The thermal stability evaluation solution revealed that degradation temperature order different structural units is DMAA < AMPS ≈ DMDAAC NVP, resistance 220 °C. Evaluation fluid demonstrated 3.5 wt % enabled resist from 15 NaCl at 230 °C, with an American Petroleum Institute (API) loss high-temperature high-pressure (HTHP) after hot rolling 4.2 22.0 mL, respectively. At temperatures, composite releases nanoparticles, which enhance density filter cake, allowing adjustable enhanced control under high-salty conditions.

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.
