“…The absorption peak at 3,421 cm -1 was attributed to the stretching vibration of N-H in AAM, which was echoed by bending vibration peak of N-H occurring at 1,551 cm -1 . The peaks at 2,979, 2,937 and 626 cm -1 were assigned to the stretching vibration of -CH 3 , -CH 2 and C-S of AAM (Guo et al 2013;Yan et al 2013), respectively. The stretching vibration peak of C=O in AAM was shown at 1,651 cm -1 .…”

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 ? .

“…10 In order to enhance the temperature resistance of PIAS, the large-volume groups of the phenyl and sulfonate groups were introduced into the molecules by free-radical, aqueous-solution polymerization. From the molecular design, the carboxyl groups were able to act on the hydrated particles and crystal nuclei in the cement slurry to retard the hydration of cement through adsorption and chelation.…”

Synthesis and performance of itaconic acid/acrylamide/sodium styrene sulfonate as a self-adapting retarder for oil well cement

et al. 2015

A novel self-adapting retarder itaconic acid/acrylamide/sodium styrene sulfonate (IA/AM/SSS, hereinafter referred to as PIAS) was synthesized by free-radical, aqueous-solution polymerization and characterized by FTIR and TG. The optimum reaction conditions of polymerization were obtained from orthogonal experiments (L3 3 ) and subsequent data analysis. According to the evaluation as a retarder, the PIAS made it possible to obtain both a long thickening time and a swift compressive strength development for cement slurry, and therefore the applicable range of bottom hole circulation temperatures to the cement slurry has been widened to 60-180 C. Moreover, the working mechanism of the self-adapting retarder PIAS was found to rely on the change of spatial structure of the molecules to retard the hydration of the cement. This paper also expounds that the delayed coagulation of the cement slurry is attributed to adsorption, chelation and "poisoning" effects of the PIAS molecules on the surface of hydrated particles or ions through XRD and SEM analyses.

“…Here, mud circulation, fluid and slurry density, cement gel strength, fluid loss, free water, cement permeability, micro annuluses and applied pressure in annulus are the key factors managing this complex phenomenon [6,19] while petroleum industry has this problem since the early 60's [7,24]. In the early of 1960's, the importance of the surface of the pipes, roughness and wettability, in the proper connection between cementcasing and cement-formation was revealed [8,9,21]. On the other hand, Wenger et al (1965) introduced a special mechanical device with the ability to connect to the casing in order to control the relevancy between the layers [10].…”

In recent years, improving the quality and composition of cement slurry has been one of the most important challenges for researchers and oil and gas well drilling industries. It has been demonstrated that, nanoparticles have made some progresses in the operational characteristics of the conventional cement. This research, via 13 experimental attempts, revealed a great improvement in compressive strength and rheological properties of the cement slurry after addition of silicon dioxide nanomaterial to the slurry. However, it did not make any significant change in the free water content of the cement and fluid loss. In the case of static gel strength analyzers (SGSA) test, transient time followed a decrementing pattern by increasing nanoparticle percentage. As a result, it met the vital goal in drilling industry via deep reduction in gas migration rate, solving the foregoing problem without having any negative effects on the other properties of the cement slurry such as thickening time. Moreover, the Mohr circles analysis demonstrated that, higher compressive strengths were achieved.
