More information. Tianjin Kelioil Engineering Material and Technology Co., Ltd. is a national high-tech enterprise specializing in the mass production of oilfield cementing additives. Fluid loss control additives are employed for maintaining a constant water/solid ratio in cement slurries downhole by controlling the rate of water loss to adjacent permeable zones through suitable viscosification; otherwise the cement slurries would lose water by filtration into these zones. Now Fluid Loss Control Agents are recognized in the industry that the quality of cementing jobs has significantly improved. This value is excessive for most cementing operations, where permeable formations are encountered or where long columns of cement will be used. SMLZ-108. Fluid-Loss-Control Additives (FLAs) are used to maintain a consistent fluid volume within a cement slurry to ensure that the slurry performance properties remain within an acceptable range.

Halad-766 fluid-loss additive is extensively used to retard foam slurries without reducing viscosity. They can either be liquid or powdered additives. There are a number of conditions that can induce fluid loss: Fluid loss additives help operators retain the key characteristics of their cement slurries, including viscosity, thickening time, density and compressive strength development. A fluid-loss additive designed for use in low-temperature wells (below 180°F or 82.2°C) to prevent retardation of compressive-strength development; acts as a dispersant as well. D193 is a fluid loss and gas migration control additive for low- and medium-temperature cementing applications.

Halad-766 fluid-loss additive is a derivitatized cellose that can be used for fluid loss and retardation in all API cement classes as well as Pozmix® cement. At bottom-hole circulating temperatures of up to 190°F, it is the most commonly used fluid loss control additive in the world. When using these fluid loss additives, cement homogeneity and flow are retained. ADVANTAGES FL-17 can be used in casing and liner cementing using fresh to saturated salt-water cement slurries. About Us. Gas Migration Control Additives. Halad-766 fluid-loss additive is a derivitatized cellose that can be used for fluid loss and retardation in all API cement classes as well as Pozmix® cement. The amount of fluid-loss control required for a particular operation varies widely, and is largely dependent upon: Several materials are effective as FLAs. It can be used in wells with bottomhole circulating temperatures (BHCTs) of 180°F (82°C) and below. It is available as a powder or a 20%\nsolution (Halad®-567L additive). Neat cement slurries normally exhibit an uncontrolled API fluid loss of at least 1,500 cm3/30 min. To convert the total amount of fluid loss into an API fluid loss value, three parameters are needed: the permeable formation area, the mudcake thickness and its permeability. Ideally, the fluid loss additive blend should be present in an amount of about 0.05 to 2.0 percent by weight of the cement, and preferably in an amount of about 0.125 to 1.0 percent by weight of the cement. The variability of each of these parameters (slurry performance properties) is dependent upon the water content of the slurry. By Svein Normann - December 12, 2017.

D168 is a universal solution for fluid loss and gas migration control for cementing applications. It can be used in wells with bottomhole circulating temperatures (BHCTs) of 180°F (82°C) and below. UFL-73 A can control fluid loss through forming tight polymer film and enhancing viscosity of the water phase. The material is nonretarding, thus making good compressive strength development possible at low temperatures. Thus, slurries that lose water can also be subject to a loss or degradation of design properties. The fluid loss additives, which are one of the three main additives on the oil cement slurry, can effectively reduce the fluid loss of oil cement slurry in the field condition and can also increase the viscosity and improve the stability of oil cement slurry [1 1. In almost any operation, loss of fluid to the reservoir formation carries a high risk of permeability damage. 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.
