“…The adsorption of anionic group on cement particles mainly recurs to electrostatic force, while the adsorption of nonionic group mainly recurs to the hydrogen bonds. The cationic group was not introduced in the polymer because the cationic polymer FLCA has the fluid loss control ability only when the dispersant is introduced in the cement slurry [3,5].…”

The fluid loss control additive plays a key role in reducing reservoir damage and improving the cementing quality of an oil well. Aiming at good fluid loss control ability and excellent dispersibility, a new dispersive type fluid loss control additive was synthesized through orthogonal experiment with 2-acrylamido-2- methyl propane sulfonic acid, acrylamide, N, N-dimethylacrylamide and maleic anhydride. The orthogonal experiment result shows that the influence on the properties of FLCA decreases in the order: PH value > monomer concentration > monomer mole ratio > initiator concentration > temperature. The result indicates that the optimal conditions for FLCA were 4/2.5/2.5/1 of mole ratio of AMPS/AM /NNDMA/MA, 32.5% total monomer concentration in deionized water, 1.0% (by weight of monomer) ammonium persulfate/sodium bisulfite, 4 of PH value, 40°Cof temperature. The synthesized copolymer was identified by FTIR analysis. The results show the dispersive type fluid loss control additive has excellent dispersibility, fluid loss control ability, thermal resistant and salt tolerant ability. As the temperature increases, the thickening time of the slurry containing the synthesized additive reduces. The copolymer is expected to be a good fluid loss control additive.

“…In each step, drilled segment is cased by steel pipes and these casing pipes are fixed by cementing operation that has been done behind them. It should be mentioned that separation of different formation layers with different pressures and fluid contents is the most important reason for cementing [1]. While the cement slurry changes its initial properties as well as its state during the operation, adjusting the setting time of the cement depends on various factors, creating different operational conditions.…”

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.

“…A wide variety of cement admixtures are currently available to enhance oil well cement slurry properties, to achieve successful placement and rapid compressive strength development for adequate zonal isolation during the lifetime of the well [8]. In general, several admixtures such as retarder, dispersant, and fluid loss additive were added to oil well cement slurries [9]. The properties of fresh and hardened cement based systems are highly depended on the type and dosage of chemical admixtures used [5,10].…”

“…The properties of fresh and hardened cement based systems are highly depended on the type and dosage of chemical admixtures used [5,10]. Recently, organic materials admixtures such as polymers are added in small quantities to modify and enhance the properties of cement products [9,11]. The effect of addition of different admixtures on the physicochemical and rheological properties of cement pastes was investigated in various studies [12][13][14][15][16][17].…”

Early hydration characteristics of oil well cement pastes admixed with newly prepared organic admixture

et al. 2018

A number of chemical and mineral admixtures are usually used in the oil-well cement (OWC) pastes to modify and control their fluidity to resist the higher temperatures and pressures during the drilling process of the well. In this study a newly prepared aliphatic organic compound namely cyclohexanone glyoxylate condensate (CG) was synthesized. The prepared compound (CG) was characterized using Fourier Transition Infrared spectroscopy (FT-IR) and microanalysis of carbon, hydrogen, oxygen and sulfur elemental analysis techniques. The effect of additions of 0.25, 0.50, 0.75 and 1 (mass%) of this admixture on the mechanical and early hydration characteristics of OWC pastes was studied. The phase composition for some selected hardened specimens was investigated using X-ray diffraction (XRD) and thermogravemtic analysis (DTGA) techniques. The results indicated that, addition of cyclohexanone glyoxylate condensate (CG) admixture to OWC pastes causes a slight retardation for the early rate of hydration of OWC. Addition of 0.25% of CG to OWC causes a slight improvement in the compressive strength values during nearly all ages of hydrations. XRD and DTGA results for the neat and CG admixed OWC pastes, indicate that the main hydration products are nearly amorphous calcium silicate hydrates (mainly as CSH-I and CSH-II), calcium sulfoaluminate hydrates (ettringite and monosulfate hydrate) as well as portlandite (CH).
