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≤1.10Note: 1), API Spec 10A of the G-high resistance to oil well cement of Jiahua, water cement ratio was 0.44. 2), slurry properties (thickening time and compressive strength)is ratio of the same is mixed with drag reducing properties of the slurry and puree. 3), braces for the test conditions. Four, packaging storage and transportation DLS oil well cement drag reducer uses three composite packaging, packaging can also be determined according to user requirements.Bags are printed product name, product standard number, net weight, batch number or production date, production plant name, trademark, and other site. Attention to moisture, sun protectionin product storage and transportation, should be placed in ventilated, cool place.
