oil well Chemical Auxiliary Agent

DLS oil well cement drag reducer (high level of product) for use Ffirst. Introduction DLS oil well cement drag reducer is a new high anti-temperature, anti-salt oil well drag reducer, mainly mixed with ketone, aldehyde and amino-sulfonate condensation.The extensive use of oil field proved that the treatment agent in the resistance to temperature, salt, and compatibility with other treatment agents is outstanding advantages. Second, characteristics and uses DLS-CC polymer main chain is -c-c connected, molecular main chain has hydroxyl, and a strong sulfonic group hydration, the cement used in well with the following features: 1), significant temperature resistance, salt resistance, the product solubility is good. 2), be used for a variety of cement slurry, high early strength cement, low free liquid. 3), good compatibility with other additives, can be compatible with other additives used in deep well cementing. Third, quality indicators 1), applicable standards: SY/T5406-1999 oil well cement drag reducer evaluation. 2), the product physical and chemical performance indexProjectIndexAppearanceThe flow Brown red powderViscosity (40% solution)mPa.s20-30Effective components,% ≥90Water,% ≤8Water insoluble,%≤2.03), mixed with 0.5% DLS (total mass of cement) cement slurry drag reducer performance consistent with the provisions of Table 2ProjectIndexFirst gradeSecond gradeThird gradeThe ratio of thickening time(85%°C,21MPa)1.0-2.01.0-2.01.0-2.0The ratio of anti- compression strength(110°C,21MPa)≥0.8≥0.8≥0.8Rheological propertiesN,≥0.60≥0.50≥0.45(85°C,Pressure)K,Pa·sn≤0.35≤0.70≤1.10 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.

Introduction DLS21 oil well cement early strength admixture is our company for oil field which develops new oil well cement additives, which is a combination of inorganic materials and organic materials in accordance with the strict molar ratio, the product is non-toxic ,tasteless and without injury, finished as the solid powder, suitable for dry mixing of cement, after joining the cement it can improve the early strength of cement; especially for low-density slurry (including the floating beads and ash slurry, etc.), so that cement slurry is stable, without sedimentation and segregation phenomena, reduce the volume shrinkage of cement, increase the compressive strength of cement and slurry overall performance, so as to improve cement slurry and the effect of formation, thus enhancing solid by quality. Second, the major technical indicators Appearance: light brown powder. Using the G-high resistance to oil well cement, water-cement ratio 0.44, DLS21 dosage of ProjectIndexInitial consistency,Bc/52°C.35 . 6MPa≤30Thicking time,min/52°C.35.6MPa≥50The ratio of anti-compressive strength and puree,(MPa/60°C.0.1MPa.8)≥1.3
