| titleOfInvention | A kind of preparation method of drilling fluid fluosilicic diluent |
| abstract | A kind of preparation method the invention discloses drilling fluid with fluosilicic diluent, its step are as follows：1) 50ml methyl methacrylates, 100ml butyl acrylates, are sequentially added in 500ml distilled water, is stirred, adds 7.5ml span 80s, stirs 1h, forms monomer pre-emulsion；2) pre-emulsion, is taken out, sequentially adds Hexafluorobutyl mathacrylate 35ml, dodecafluoroheptyl methacrylate 25ml, γ methacryloxypropyl trimethoxy silane 25ml, vinyltrimethoxy silane 40ml, ultrasonic vibration disperses 10min；3), take 1/5 emulsion through ultrasonic vibration to add ammonium persulfate 3g, add flask heating water bath, ammonium persulfate 3g and distilled water are added after reaching reaction temperature；4), after emulsion has blue light to glow, remaining 4/5 emulsion was added dropwise in 15 minutes, then adds ammonium persulfate 3g and is incubated 1h, finally take out；The diluent prepared using this preparation method, can reduce the interaction between clay, make the viscosity of drilling fluid reduce. |
