“…These structures have the ability to wrap water that is un ltered in the liquid phase to prevent its loss in addition to adhering rmly to the cake of ltering and blocking the pores throughout the lter cake. From the research above, it can be inferred that the density is more advantageous to improve the condition inside the lter cake, hence lowering the water loss, the closer the ne mesh construction and membrane's framework are stacked [29,30] .…”

“…Therefore, researching new uid loss additives with high temperature resistance, good compatibility with other additives, and no negative impact on uid loss performance is currently a topic of great research value and signi cance. At present, there have been reports on the research of zwitterionic uid loss additives in high-temperature and ultra-high temperature cementing [15][16][17][18][19][20][21][22][23] , but the molecular structure contains a large number of amide groups, Certain compounds are prone to hydrolysis when exposed to high temperatures and strong alkali. This hydrolysis phenomenon can lead to an abnormal thickening during the cement slurry, resulting in an adverse impact on the mechanical properties development of cement paste.…”

At high temperatures, the salt resistance of fluid loss agents is poor. In order to achieve the goal of high temperature salt resistance, a zwitterionic fluid loss agent was designed and synthesized.Using sodium p-styrene sulfonate, itaconic acid, acrylamide, and dimethyldiallylammonium chloride as raw materials, a water loss agent SMFD was synthesized through aqueous solution polymerization. The structural characterization of the polymer showed that the molecule contains the designed functional groups, has a moderate molecular weight, and can withstand heat at temperatures above 220 ℃. The microstructure of the polymer solution exhibits a three-dimensional network structure. At 150 ℃, the water loss of 4% fluid loss additive is less than 50mL, and it still performs well in semi saturated saline and saturated saline environments. Additionally, the impact of the fluid loss additive on the strength, rheological properties, settlement stability, and other relevant characteristics of the cement slurry is minimal, thereby satisfying the necessary criteria for successful well cementing. The utilisation of microscopy, scanning electron microscopy, and organic carbon adsorption testing techniques revealed that the application of SMFD enhances the characteristics of cement filter cakes. This improvement is attributed to the formation of a polymer network through processes such as ion association, adsorption, and polymer synergy. The polymer network effectively fills the voids between cement particles, resulting in a more compact filter cake structure. Consequently, this leads to a reduction in water loss of the cement slurry.

“…The mass loss comes from the thermal decomposition of unstable oxygen-containing functional groups (C=O, COOH, etc.) in the fluid loss additive [37,38]. The decomposition temperature of the quaternary copolymer was more than 360 • C, indicating that the fluid loss additive ADAM-J had good temperature resistance.…”

Conventional fluid loss additives have difficultly controlling the water loss of cement–metakaolin slurry with semi-saturated brine cement slurry and limiting it to less than 50 mL (30 min)−1. This paper describes the development of an anti-salt fluid loss additive for metakaolin–cement systems. This study adopted the aqueous solution polymerization method; selected four kinds of monomers, namely 2-Acrylamido-2-methylpropane sulfonic acid (AMPS), N,N-Dimethylacrylamide (DMAA), acrylamide (AM), and methyl acrylate (MA); and performed a single-factor experiment on the proportion of monomer, reaction temperature, initiator dosage, and developed fluid loss additive, which has a high salt tolerance and temperature tolerance. This fluid loss additive can resist salt until saturation, and it can control fluid loss in 24 mL·(30 min)−1 when its dosage is 2%. The fluid loss additive can achieve the effect of fluid loss reduction by increasing the filtrate viscosity, forming a flexible elastic adsorption layer via adsorption, and blocking mud cake pores.
