Our objective in the research described here was to use new monomers to synthesize a novel fluid loss additive. In order to ensure that it has a superior performance to control the fluid loss of the oil cement slurry, the macromolecular polymers should have rigid radical, strong absorption groups to the oil cement particles and superior thickening properties [6, 7].

Fluid Loss Control Additives. As cement is pumped across a permeable rock surface under pressure, cement filtrate, or water is lost or squeezed out of the cement into the rock. Cement fluid loss must be controlled to obtain the right rheological properties for placing the cement and to ensure a good cement bond to pipe and formation.

Halad-413 additive can help control fluid losses in seawater slurries, salt-saturated slurries, and slurries containing 5% KCl or 2% CaCl 2. Depending on the slurry design, Halad-413 additive usually acts as a mild dispersant and cement retarder.Consequently, slurry rheology is lowered, and free-water values are increased, helping eliminate the ...

A chemical additive used to control the loss of fluid to the formation through filtration. In cementing operations, loss of the aqueous phase can severely affect the performance of the slurry and set cement. In almost any operation, loss of fluid to the reservoir formation carries a high risk of permeability damage.

with various additives such as accelerators, retarders, friction loss. controllers, polymers, etc. Cement additives are used to improve. the rheology, strength, and curing time. 6 ...

Jan 01, 2015· In hydraulic cement slurries, fluid loss additives based on sulfonated or sulfomethylated lignins have been described. Sulfonated or sulfomethylated lignins are reacted with phenol-blocking reagents, such as EO, PO, or 1,2-butylene oxide . The fluid loss and thickening time characteristics of the cement slurry is altered, either by increasing ...

A well bore cementing composition and method are shown in which a hydraulic cement, water and a non-retarding fluid loss additive are combined to form a cementing slurry. The non-retarding fluid loss additive is a copolymer of a first non-ionic water soluble monomer which resists hydrolyzing in a cement slurry and a second anionic monomer.

Cement Fluid Loss Control Additives Our Cement Fluid Loss Control Additives are Designed to Control The Filtration Rate of Many Water-Based Fluid Systems. As cement is pumped across a permeable rock surface under pressure, cement filtrate or water is lost or squeezed out of the cement …

and to avoid loss of grout flowing out of control. To ensure uniform dispersion of the additive, cement, sand, Cebex FCC422 should be mixed thoroughly in dry condition and then with precisely measured quantity of water. Water to cement ratio can be 0.4 to 0.44, depending on the type of cement, sand and workability required. Free fall concrete mixer

effective cement slurries by adding additives to enhance or modify to achieve desired cement properties [2]. The additives added in cement are an integral part of the well design, construction and integrity. Therefore, a through lab testing must be carried for any new cement design or additive before applied the cement slurry in the field.

Cement slurries can lose water to permeable zones causing a number of problems, such as insufficient mud displacement, high viscosity, unwanted change of set-time, and lack of final compressive strength. Fluid loss additives reduce water loss through the cement filter cake, which makes them especially useful in squeeze cementing.

Oct 30, 2019· 1. Introduction. A significant kind of polymer which was added to oil well cement was so-called fluid loss additive (FLA). Their main purpose was preventing water mud filtrate entering the formation, resulting in the deterioration of cement slurry's fluidity and the destruction of the reservoir, .Owing to the excellent performance of FLA, a large number of scholars had extensively studied ...

Fluid-Loss Additives Cementing Technology Manual LA-2 Description and Primary Function: LA-2, a syn-thetic latex emulsion, is a fluid-loss additive that imparts good bonding and perforating properties. Cement that contains LA-2 is more resistant to acid and corrosive formation fluids than cement contain-ing conventional fluid-loss additives.
