Abstract
The present invention relates to an emulsion polymer for drilling fluid, which is a treating agent for the drilling fluid. The present invention solves the problems of the existing domestic drilling fluid, and is made of the following materials: caustic soda, acrylic acid solution, 2-methyl 2-acrylamido propanesulfonic acid, acrylamide, white oil, emolsifier span-80, span-60, tween-80, and initiating agent solution. The emulsion polymer for drilling fluid has the advantages of uniform molecular weight distribution, high dissolving speed and high efficacy, and the product is in an emulsion state.
Description
One, technical field: the present invention relates to a kind of additive for drilling fluid, especially emulsion polymer for drilling fluid.
Two, background technology: with vinylformic acid and acrylamide is to have formed a kind of drilling fluid system at home after main raw material copolyreaction polymer treatment agent seventies of generating, remain a kind of main additive for drilling fluid up to now, but the polymkeric substance that uses all is solid state now, dissolution rate is slow, blob of viscose and flake appear in the use easily, directly add in the drilling fluid and very easily sifted out, cause the lag-effect of great waste and property of drilling fluid, use extremely inconvenient by reciprocating sieve.
Three, summary of the invention: the purpose of this invention is to provide a kind of even molecular weight distribution, product is the latex state, dissolution rate is fast, the emulsion polymer for drilling fluid that usefulness is high, it has solved the problem that present domestic drilling fluid exists with polymkeric substance, the object of the present invention is achieved like this, it is made by following material, caustic soda 20-50kg, acrylic acid solution 40-100kg, 2-methyl 2-acrylamido propanesulfonic acid 50---80kg, acrylamide 120---200kg, white oil 150---180L, emulsifier span---80 15---20kg, sapn---60 5---10kg, tween---80 5---10kg, initiator solution 2L
Its preparation method is: the preparation of the first step water, in the configuration still, add water 100---200kg, and open and stir the adding caustic soda, the dissolving back adds acrylic acid solution, 2-methyl 2-acrylamido propanesulfonic acid, acrylamide, transfer ph=8---10, be cooled to below 60 ℃, stop to stir while dissolving.The second step emulsification adds the above-mentioned solution that configures in the emulsification still, adds white oil, opens emulsor I, adds emulsifying agent, opens emulsor ∏ simultaneously, continues emulsification 20min, and temperature is controlled at below 60 ℃.Three-step reaction, emulsion is put into reactor, opens stirrer, adds initiator solution 2L, stops to stir behind the stirring 5min, leave standstill, the record temperature variation, blowing got final product when temperature dropped to below 40 ℃ after reaction was finished.
Emulsion polymer for drilling fluid is because in the emulsified state polymerization, even molecular weight distribution, and product is the latex state, dissolution rate is fast, the usefulness height, performance is better than solid phase prod, and is therefore easy to use, loss is little, comprehensive cost is low, owing to increased oil phase and novel monomeric 2-acrylamido 2-methyl propane sulfonic acid in synthetic, contains anticalcium, magnesium and temperature resistance group in the molecule in addition, its anti-salt, anticalcium, magnesium and temperature resistance ability are strong, and the adding of oil phase can also improve the oilness of drilling fluid; Have the dehydration of reduction in this product adding drilling fluid, improve drilling fluid lubricating, regulate the drilling fluid flow pattern, wrap by the multi-efficiency of drilling cuttings, the slump in of drawing up; This product has that dosage is little, good stability, have wide range of applications, characteristics such as effect is remarkable.
Four, embodiment: the present invention is made by following material, caustic soda 20-50kg, acrylic acid solution 40-100kg, 2-methyl 2-acrylamido propanesulfonic acid 50---80kg, acrylamide 120---200kg, white oil 150---180L, emulsifier span--80 15---20kg, sapn--605---10kg, tween---80 5---10kg, initiator solution 2L
Its preparation method is: the preparation of the first step water, in the configuration still, add water 100---200kg, and open and stir the adding caustic soda, the dissolving back adds acrylic acid solution, 2-methyl 2-vinylformic acid amido propanesulfonic acid, acrylamide, transfer ph=8---10, be cooled to below 60 ℃, stop to stir while dissolving.The second step emulsification adds the above-mentioned solution that configures in the emulsification still, adds white oil, opens emulsor I, adds emulsifying agent, opens emulsor ∏ simultaneously, continues emulsification 20min, and temperature is controlled at below 60 ℃.Three-step reaction, emulsion is put into reactor, opens stirrer, adds initiator solution 2L, stops to stir behind the stirring 5min, leave standstill, the record temperature variation, blowing got final product when temperature dropped to below 40 ℃ after reaction was finished.
