Description
Technical field
The present invention relates to oil and gas well drilling technical field, exactly relate to a kind of preparation method of drilling fluid positively charged ion fluosilicic thinner.
Background technology
Along with going deep into of oil-gas exploration and development, oil-gas exploration is to deep formation and marine development, well depth increases gradually, drilling strata condition is increasingly sophisticated, drilling engineering is had higher requirement to Drilling Fluid Technology, especially for the drilling fluid of deep-well high solid loading, the contradiction between rheological, inhibition, temperature resistance etc. of comprehensive solution drilling fluid is particularly difficult, and particularly the thermal stability problems of Drilling Fluid Technique for Deep is the key of research both at home and abroad always.And viscosity-depression agent is one of indispensable additive for drilling fluid in drilling process, it can play viscosity reduction, regulate the effects such as drilling fluid rheology, and can safeguard the stable performance of drilling fluid, be indispensable additive for drilling fluid in drilling process.
Publication number is CN101368090, publication date is that the Chinese patent literature on February 18th, 2009 discloses a kind of silicon-fluorine high temperature resistant thinner dry powder for drilling fluids, it is a kind of New well drilling solution additive, it adopts Si―H addition reaction method by allyl polyethenoxy ether, silicon-fluorine polymer thing is reached after fluorochemical monomer and coupling agent and silicon oil of low hydrogen content carry out graft copolymerization, and then add deionized water, humic acids, sodium cellulosate, caustic soda, stoichiometric number hour at 120 DEG C ~ 130 DEG C, products therefrom is silicon-fluorine high temperature resistant thinner dry powder for drilling fluids product after air stream drying, its outward appearance is black flow solids powder, there is excellent viscosity reduction characteristic, the anti-collapse function of retaining wall, dispersion is had to drilling fluid system, lubrication, the effects such as froth breaking, and the shale hydration expansion that in drilling process, mud filtrate invasion stratum causes can be eliminated, improve borehole wall stability, safeguard after Deal With Drilling Fluid that the phase is long.
Simultaneously, thinner conventional is at present xylogen, tannin extract class viscosity-depression agent, no matter be thinner dry powder disclosed in CN101368090 patent documentation or xylogen, tannin extract class viscosity-depression agent, its temperature resistance poor effect, and dilution effect is unstable, when temperature reaches 130 DEG C, treatment cycle only maintains about 3 days, and treatment capacity is large, simultaneously, adding of traditional viscosity-depression agent, destruction can be brought to hydrocarbon zone.
Summary of the invention
The present invention is intended to for the defect existing for above-mentioned prior art and deficiency, a kind of preparation method of drilling fluid positively charged ion fluosilicic thinner is provided, this preparation method technique is simple, adopt thinner prepared by this preparation method, the interaction between clay can be reduced, the viscosity of drilling fluid is reduced, good diluting effect is produced to drilling fluid, effectively can prevent the hydration swelling of mud shale simultaneously.
The present invention realizes by adopting following technical proposals:
A preparation method for drilling fluid positively charged ion fluosilicic thinner, is characterized in that step is as follows:
1), in 500ml distilled water, add 50ml methyl methacrylate, 100ml butyl acrylate successively, stir, add 7.5ml span 80, stir 1h, form monomer pre-emulsion; The monomer conversion gone out by this proportions is the highest.
2), pre-emulsion is taken out, add Hexafluorobutyl mathacrylate 35ml, dodecafluoroheptyl methacrylate 25ml, γ-methacryloxypropyl trimethoxy silane 25ml, vinyltrimethoxy silane 40ml successively, ultrasonic vibration dispersion 10min, ratio-dependent comes from the radical amount that all ingredients can participate in reacting;
3), get 4/5 and add ammonium persulphate 3g through the emulsion of ultrasonic vibration, add flask heating in water bath, add ammonium persulphate 3g and distilled water again after arriving temperature of reaction, add at twice, the various compositions contributed in emulsion fully react;
4), after emulsion has blue light to glow, in 15 minutes, drip remaining 1/5 emulsion, then add ammonium persulphate 3g and be incubated 1h, finally taking out, the highest by the output of final gained after this substep mixing;
5), be cooled to room temperature, discharging is filtered and is obtained the finished product.
Compared with prior art, the beneficial effect that reaches of the present invention is as follows:
In the present invention, adopt step 1)-5) the thinner for preparing of mode, it has following technique effect:
1, this thinner has environmental protection characteristic, its degradation production it be silicone molecules, and CO can be decomposed into further
2, H
2o, SiO
