Abstract
The invention discloses a preparing method of a silicon viscosity reducer for the drilling fluid, comprising steps: step one, adding proper water in a reactor, then feeding methyl chlorosilane, stirring and reacting for generating mixed solution, cooling the mixed solution; step two, adding aqueous alkali into the cooled reaction solution for complete reaction, feeding aluminium sulphate solution, stirring and reacting for a period, forming the silicon viscosity reducer for the drilling fluid. The prepared viscosity reducer has strong high-temperature (more than 240 DEG C) resistance and high compatibility with the other substances, good mud stream rheological property, dilution, viscosity reduction property and lubricating property. The working substance content is higher or equal to 16%; the chloride content is lower or equal to 10% and the viscosity reduction ratio is higher or equal to 80% at the room temperature and the viscosity reduction ratio at 220 DEG C for 16 hours is higher than or equal to 70%.
Description
Technical field
The present invention relates to a kind of preparation method of silicon viscosity reducer for drilling fluid.
Background technology
The high-temperature resistance of present silicon viscosity reducer is more weak, and poor with the compatibleness of other products.
Summary of the invention
The invention provides a kind of preparation method of silicon viscosity reducer for drilling fluid, the viscosity-depression agent that it makes not only high-temperature resistance is strong, and has good viscosity-reducing performance.
The present invention has adopted following technical scheme: a kind of preparation method of silicon viscosity reducer for drilling fluid, it may further comprise the steps: step 1, an amount of water is added in the reactor, and then adding methyl chlorosilane, carry out again generating mixing solutions behind the stirring reaction, after question response finishes mixing solutions is cooled off; Step 2; In cooling afterreaction solution, add alkaline solution and fully react, after adding alum liquor stirring reaction for some time again after the reaction, form silicon viscosity reducer for drilling fluid.
Adding the time of alum liquor stirring reaction time in the step 2 of the present invention is 4 hours.The silicon viscosity reducer for drilling fluid that makes in the step 2 of the present invention is water white transparency or weak yellow liquid, and its pH value is 13-14, and proportion is 1.1-1.3.
The present invention has following beneficial effect: the viscosity-depression agent that adopts above method to make has very strong high-temperature resistance, high temperature resistance can reach more than 240 ℃, and it is strong with the compatibility ability of other materials, the good stability of while drilling fluid rheology and high temperature resistance thereof, have good dilution, viscosity reduction and lubricity, the content of its working substance 〉=16%, muriatic content≤10%, its viscosity break ratio at ambient temperature 〉=80%, 16 hours viscosity break ratio 〉=70% under 220 ℃ condition.
