Oil well cement fluid loss additive

Oil well cement fluid loss(filtrate reducer) DLS60 Help Ffirst. Introduction DLS60 oil well cement fluid loss additive is the company who develop new oil well cement additives for oil field, which is a combination of polymer materials and inorganic materials in accordance with the strict molar ratio, The finely ground mixture obtained, the product itself is non-toxic and tasteless, finished as the tiny white or yellow powder, without injury.After the product join the cement, it can effectively enhance the effect of slurry fluid loss, under the effect of the pressure to quickly form a dense film that keeps water in the mud in the water filtration to the ground, meanwhile it can also prevent the formation of fluidand gas permeability to water slurry, maintain stability in slurry and improve the overall performance of slurry, so as to improve cement slurry and the formation effect, and thus improve cementing quality. Second, the major technical indicators Using the standard G-class oil well cement with high resistance, distilled water, DLS60 products effective dosage 1.2% BWOC and with dispersant application, under the conditions of 0.44 water-cement ratio, cement major technical indicators:ProjectIndex requirmentsInitial consistency BC≤30Free liquid ml/70ºC. Pressure≤3.5Water lossml/90ºC.6.9MPa.30min≤50Thicking time min/85ºC.50MPa>60anti- compression strength MPa/110ºC.21MPa.24h≥14Third, application: DLS60 oil well cement fluid loss additive suitable for application in dry mixed with cement. Four, packaging, transport, storage This product uses the three composite packaging, net weight 25Kg ± 0.2Kg, packaging can also be identified according to user requirements; transport should pay attention to pack lightly, light up, prevent damage; store the goods in storage which must be ventilated, dry, clean, when in storage and transportationare not mixed with hazardous substances, stacking the ground must have a certain distance from the sun, rain, DLS60 oil well cement fluid loss agent storage is kept for one year.
