Chat OnlineA fluid loss additive for addition to a cement slurry used in cementing a casing string in a wellbore the additive reduces loss of water from the slurry into the formation resulting in a better cement job the additive is comprised of partially hydrolyzed polyvinyl acetate polymer calcium sulfate a crosslinker for the polymer and optionally a defoamer
Chat OnlineFlowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or compaction the effect of superplasticizers lasts only 30 to 60 minutes depending on the brand and dosage rate and is followed by a rapid loss in workability
Chat OnlineFluid loss control additives cement slurries can lose water to permeable zones causing a number of problems such as insufficient mud displacement high viscosity unwanted change of settime and lack of final compressive strength chat online fluid loss additive for cement wide range
Chat OnlineA 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
Chat OnlineThe fluid loss of modified aluminate phosphate cement system with excellent co 2 resistant ability cannot meet the demand of cementing engineering and the conventional fluid loss additive lose effectiveness in this cement system the aim of this paper is to reveal the failure mechanisms of the conventional fluid loss additive and develop one kind of amphoteric ion polymer to control the fluid
Chat OnlineLoss of fluid from a slurry design can have serious effects on many key slurry parameters and cement placement when a fluid loss additive is included in a cement slurry design it will help maintain desired characteristics and properties such as rheology thickening time density and compressive strength
