A terpolymer comprising of sodium styrene sulfonate (SSS), n-methylol acrylamide (HAM), and acrylic acid (AA) was synthesized by aqueous free radical copolymerization and evaluated as fluid loss additive (FLA) in oil well cement. In this article, HAM is first introduced in the preparation of FLA as an environment-friendly monomer, which effectively improves the adhesion and fluid loss control of the terpolymer. The experimental synthesis conditions were optimized by orthogonal experiments. The molecule weight of the terpolymer was determined by gel permeation chromatography. The molecule structure of the synthesized terpolymer was verified by Xray photoelectron spectroscopy and Fourier transformer infrared spectrum. The thermal stability of the synthesized terpolymer was tested by thermogravimetry (TG). The structure of the terpolymer aqueous solution was observed by scanning electron microscope. The results show that SSS/HAM/AA has an excellent thermal resistant. The thermal degradation is not obvious before 295.2 8C. Furthermore, the microstructure of SSS/HAM/AA in water conducive to good fluid loss control ability. When the dosage of SSS/HAM/AA is up to 2.0% in fresh water cement slurry, the filtration loss [FL (HTHP) ] can be controlled within 50 mL at 90-150 8C. SSS/HAM/AA has an excellent property of reducing filtration loss.

“…The salt solution is a kind of strong electrolyte solution and the fluid loss of brine cement slurry is difficult to control. The abilities of fluid loss control of many kinds of filtrate reducer will be weaken and even disappear in brine cement slurry . The test results indicate that the WSP has excellent salt‐tolerance property because a lot of monomers with stable sulfonic acid group (

{SO}_{3}^{-}

) are introduced in the WSP, which is not sensitive to the salt ions.…”

A new water‐soluble polymer was prepared and evaluated as a filtrate reducer for oil well cementing. The filtrate reducer (WSP) was synthesized from 2‐acrylamido‐2‐methylpropane sulfonic acid (AMPS), acrylic acid (AA), dimethyl acrylamide (DMAA), and sodium allylsulfonate (SA) by aqueous free radical polymerization. The synthesis conditions were optimized by orthogonal experiment. The molecule structure of the synthesized copolymer (WSP) was verified by Fourier transformer infrared spectrum (FTIR) and nuclear magnetic resonance hydrogen spectroscopy (1H‐NMR). The molecule weight of the synthesized copolymer was determined by gel permeation chromatography (GPC). The thermal stability of the synthesized copolymer was tested by thermogravimetry and differential thermogravimetry (TG and DTG). When the dosage of WSP is up to 3% in fresh water cement slurry, the FLAPI can be controlled within 58 mL. In 37% salt water cement slurry, the FLAPI can be controlled within 90 mL when the dosage of WSP is 5%. The thermal degradation of WSP is not obvious before 289 °C. Compared with a commercial filtrate reducer BS‐100L and a reported copolymer HTF200C, the WSP has better performance. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43824.

“…It was reported that the copolymer consisting of AMPS and acrylamide (AM) (coded as AAM) had a good performance reducing the fluid loss in oil well cementing (Tao et al 2011). To further improve the performance of FLA, N,Ndimethyl acrylamide (DMAM) was used instead of AM to copolymerize with AMPS, and the copolymer synthesized (coded as ADM) was found to have a stronger temperature tolerance, resulting from reinforcement of molecular rigidity due to the existence of -CH 3 (Guo et al 2012). However, a more detailed study about performance of ADM was still needed under complicated formation environment.…”

Acrylamide polymer, as one type of fluid loss agent (FLA), had attracted a strong interest in the applied petroleum research because of its outstanding characteristics of thickening and filtration control. The aim of this study was to synthesize a series of binary FLA using different acrylamide monomers and analyze the effect of monomer structure on the fluid loss control performance of FLA. Three kinds of FLA with the monomer of 2-acrylamido-2-methyl propane sulfonic acid (AMPS) were prepared by polymerization of AMPS with acrylamide (AM), N,N-dimethyl acrylamide (DMAM), N,N-diethyl acrylamide (DEAM), respectively, and characterized by FTIR, 1 H-NMR and 13 C-NMR. The results showed that the FLA prepared by AMPS and DMAM (coded as ADM) showed the best water-retaining capacity, which can be attributed to its moderate rigidity group of-CH 3. It was also revealed that the tolerance of cement slurry containing ADM to Ca 2? was stronger than that to Mg 2? and Na ? .
