The high belite cement retarder prepared by means of the method is small in adding amount required by cement, low in cost, wide in applied temperature range, stable in chemical properties and capable of improving rheological property of cement paste and quality of the cement.
Description
Technical field
The present invention relates to a kind of preparation method of retardant, especially relate to a kind of preparation method of high belite cement setting retarder.
Background technology
Cement setting retarder normally is used for the grout that cement job is used; Such as; In oil gas well cementing job; Grout is pumped in the well,, reach packing oil, gas, water layer to protect the purpose of productive zone and support protective casing through grout being replaced the annular space between sleeve pipe and the well for slurry.Cement should have good pumpability delivering to before the desired position.Along with the carrying out of hydration reaction in the cement, when force of cohesion acquired a certain degree, cement will lose flowability and can't construction operation, and therefore, the thickening time of grout is the control well cementing operation, guarantee the key parameter of construction safety and cementing quality.In order to control the thickening time of grout more accurately, must in grout, add retardant to delay the reaction between cement and the water, regulate the thickening time.
When high belite cement is used in the place that needs the control cement thickening time; In oil gas well water filling operation; When perhaps other need control in the place of thickening time, condensing of the high belite cement of processing with anhydrite was too fast, is difficult to the smooth construction operation.At present, widely used cement setting retarder is used in the high belite cement, and the bad control of cement setting time also brings difficulty to construction operation.
Summary of the invention
The technical problem that the present invention will solve is, overcomes the deficiency of prior art, and a kind of preparation method who improves the high belite cement setting retarder of slurry flowing performance-changing is provided.
The present invention solve the technical problem the technical scheme that is adopted, and a kind of preparation method of high belite cement setting retarder comprises the steps:
(1) take by weighing following raw materials by weight percent: 2-acrylic amide-2-methyl propane sulfonic acid 40-60%, Hydrocerol A 20-30%, Sodium chromate-51Cr 10-20%, bio-surfactant 5-10%, each material per-cent sum is 100%;
Preferred weight percent is: 2-acrylic amide-2-methyl propane sulfonic acid 55%, Hydrocerol A 25%, Sodium chromate-51Cr 15%, bio-surfactant 5%;
Said bio-surfactant preferred nonionic surfactants;
Further, the preferred tween 20 of said nonionogenic tenside;
(2) under 50-70 ℃, 2-acrylic amide-2-methyl propane sulfonic acid is dissolved in the aqueous ethanolic solution that volume(tric)fraction is 30-80%, the weight of said aqueous ethanolic solution is 1-1.5 times (preferred 1.2 times) of 2-acrylic amide-2-methyl propane sulfonic acid weight;
(3) in the ethanolic soln of step (2) gained 2-acrylic amide-2-methyl propane sulfonic acid, add Hydrocerol A earlier, add Sodium chromate-51Cr again, stir, then at 75-90 ℃ of following insulation reaction 2-3 hour;
(4) in step (3) gained solution, adding bio-surfactant under 40-60 ℃, constant temperature stirring reaction 0.5-1 hour promptly gets the high belite cement setting retarder.
The application of the high belite cement setting retarder that the present invention makes: the high belite cement setting retarder that will be equivalent to high belite cement weight 0.02-1.2% (preferred 0.3-0.7%) adds in the high belite cement, and stirring and evenly mixing gets final product.
The high belite cement setting retarder that uses the present invention to make is through introducing charged negative and positive particle, under the charge repulsion effect; Delay moving of calcium ion, reduce the electrostatic attraction of silicate ion, thereby delay the polymerization of silicate ion; Stop the generation of hydrated calcium silicate; Simultaneously, bio-surfactant is adsorbed onto the surface of reaction product, reaches retarding effect through dual function.
The high belite cement setting retarder that the present invention makes, addition is little, and cost is low; Applicable temperature a wider range generally all can use 30-100 ℃ of scope; As with the compound use of other admixtures, Applicable temperature is wider; Stable chemical performance, dosage does not have susceptibility, and the multiviscosisty tracing pattern is good; And other performances to grout have no adverse effect, and can improve the strength of cement of 5-10%, improve the rheological property of grout, improve the quality of cement.
