“…3440 cm −1 and 1218 cm −1 are the stretching vibration absorption peaks of –NH and –CN in AMPS. 14 1043 cm −1 and 628 cm −1 are ascribed to the asymmetric stretching vibration of –SO 3 and S–C in AMPS, respectively. 1658 cm −1 belongs to the stretching vibration absorption peak of the carbonyl group in AM.…”

“…The absorption vibration peak at 1195 cm −1 and 1042 cm −1 are S=O stretching vibrations of the sulfonic group in AMPS, and the peak at 629 cm −1 conforms to the absorption vibration peak of the C-S bond on AMPS. No vibration peak of the C=C double bond at 1600–1640 cm −1 indicates that all reaction monomers were involved in the synthesis reaction and no monomer residue [ 30 ]. The results of AADN FTIR spectra show that the synthesized product is consistent with the designed structure.…”

With the exploration and development of high-temperature and high-salt deep oil and gas, more rigorous requirements are warranted for the performance of water-based drilling fluids (WBDFs). In this study, acrylamide, 2-acrylamide-2-methylpropanesulfonic acid, diallyl dimethyl ammonium chloride, and N-vinylpyrrolidone were synthesized by free radical copolymerization in an aqueous solution to form a temperature and salt-resistant zwitterionic polymer gel filtration loss reducer (AADN). The zwitterionic polymer had excellent adsorption and hydration groups, which could effectively combine with bentonite through hydrogen bonds and electrostatic attraction, strengthening the hydration film thickness on the surface of bentonite, and promoting the stable dispersion of drilling fluid. In addition, the reverse polyelectrolyte effect of zwitterionic polymers strengthened the drilling fluid’s ability to resist high-temperature and high-salt. The AADN-based drilling fluid showed excellent rheological and filtration control properties (FLAPI < 8 mL, FLHTHP < 29.6 mL) even after aging at high-temperature (200 °C) and high-salt (20 wt% NaCl) conditions. This study provides a new strategy for simultaneously improving the high-temperature and high-salt tolerance of WBDFs, presenting the potential for application in drilling in high-temperature and high-salt deep formations.

“…20−24 This type of retarder achieves the aim of inhibiting the oil well cement hydration at high temperatures through its strong adsorption and complexation behavior. 16,25 However, it has been found both in laboratory research and field application that the addition of polycarboxylic additives could lead to abnormal thickening behaviors of oil well cementing slurry systems at high temperature, such as rapid thickening, abnormal gelation phenomenon (AGP), thickening time inversion, and so on. 26−28 In laboratorial research, the thickening experiment is commonly utilized to monitor the flow state changes of cement slurry during its dynamic hydration reaction and draws a thickening curve to record the real-time consistency value of the slurry (unit: Bc 29 ).…”

The class G oil well cement is a type of special cement that can be subjected to a high temperature formation environment. It was found that the class G cement tail slurry with a low polycarboxylic retarder dosage (usually ≤1% by weight of cement) was more prone to cause the abnormal gelation phenomenon (AGP) than the lead slurry with a high retarder dosage at a high temperature (usually when T ≥ 120 °C). This study aimed at the occurrence mechanism of this unfavorable phenomenon that seriously endangers the cementing security. Results showed that the abnormal gelatinous region underwent premature hydration; namely, the calcium hydroxide and calcium silicate hydrate (C−S−H) content were all higher than the nongelatinous region, while the copolymer content was the opposite. Correspondingly, the theory of "premature hydration and crystal nucleation" was proposed to explain the abnormal gelation mechanism of a cementing tail slurry with an insufficient retarder dosage. Furthermore, a novel functionalized copolymer retarder "PAIANS" was synthesized to alleviate the AGP.
