Abstract
The invention designs drilling fluid-used silicofluoride high-temperature resistant viscosity breaker dry powder, which is a novel drilling fluid additive. The silicon hydrogen addition process is used for graft copolymerization of allyl polyethenoxy ether, fluoric monomers, coupling agents and low-hydrogen silicone oil to get a silicofluoride polymer; deionized water, humic acid, sodium cellulosate, sodium hydroxide are added; the mixture reacts for a plurality of hours at 120 to 130 DEG C; after the products from the reaction are dried through air flow, the drilling fluid-used silicofluoride high-temperature resistant viscosity breaker dry powder is got which is black flowing solid powder, and has the characteristic of breaking viscosity and the functions of protecting wall and preventing the wall from falling down. The drilling fluid-used silicofluoride high-temperature resistant viscosity breaker dry powder can disperse, lubricate and defoam the drilling fluid system, and can eliminate the hydration and expansion of mud shale caused by the invasion of the drilling fluid into the formation during drilling, and improve the hole stability. The maintenance period is long after holes are treated with the drilling fluid.
Description
Technical field
The present invention relates to a kind of high temperature resistant thinner, is the silicon-fluorine high temperature resistant thinner dry powder that a kind of drilling fluid is used.
Background technology
Continuous expansion along with the oil field prospecting developing zone, the complicacy of drilling strata increases, and special well also increases considerably year by year simultaneously, and is more and more higher to the performance requriements of additive for drilling fluid, for satisfying these technical requirementss, Silicon Valley chemical research institute has developed silicon-fluorine high temperature resistant thinner dry powder again, and this product is a kind of black flow solids powder, and is nontoxic, pollution-free, soluble in water, have excellent viscosity reduction characteristic, anti-salt, anticalcium, high temperature resistance also have certain leak-off effect of falling simultaneously.
Summary of the invention
The objective of the invention is to reduce drilling cost, improve drilling benefit, a kind of production method of silicon-fluorine high temperature resistant thinner dry powder for drilling fluids is provided in order to overcome the defective of prior art.
Purpose of the present invention can realize by following technical measures;
A kind of production method of silicon-fluorine high temperature resistant thinner dry powder for drilling fluids.Its production technique is for to join allyl polyethenoxy ether, fluorochemical monomer, silicon oil of low hydrogen content in the reactor in the ratio of 3:2:2, temperature of reaction is controlled at 80 ℃～85 ℃, after the underpressure distillation 1 hour, add coupling agent, be warming up to 100 ℃ ± 0.5 ℃ then, underpressure distillation controlled to 150 ℃～160 ℃ to the temperature of system after 1 hour again, reacting after 6-10 hours is to reach the silicon-fluorine polymer thing after the graft copolymerization, and this polymkeric substance plays a part dominance at silicon-fluorine high temperature resistant thinner dry powder.With silicon-fluorine polymer thing, humic acids, sodium cellulosate, caustic soda is that raw material adds in the enamel reaction still, adds deionized water, promptly gets silicon-fluorine high temperature resistant thinner dry powder for drilling fluids with the air stream drying oven dry in reaction under 120 ℃～130 ℃ after 3～5 hours.
