Abstract
The invention discloses an oil drilling slurry viscosity reducer, which comprises the following components in part by weight: 6.9 parts of acrylic leftover, 4.2 parts of sodium hydroxide, 8 parts of formic acid, 17 parts of 30 percent hydrogen peroxide and 64 parts of water. A preparation method for the oil drilling slurry viscosity reducer comprises the following steps: (1) adding 6.9 parts by weight of acrylic leftover into a reaction kettle, and then adding 64 parts by weight of water and 4.2 parts by weight of sodium hydroxide; (2) using steam to heat the reaction kettle until the reaction solution is boiled and hydrolyzing for 5 hours; (3) after hydrolyzing, reducing the temperature to below 50 DEG C, using 8 parts by weight of formic acid to adjust the pH value to neutral, stirring the mixture, slowly adding 17 parts by weight of hydrogen peroxide with stirring, and after no bubbles exist, emptying into a material storage tank; and (4) drying the materials in the material storage tank at a temperature of 100 DEG C and then grinding the dried materials into power or particles. The product of the invention has high temperature resistance and salt resistance, can be suitable for various water-base drilling fluids and can be used for well cementation in high temperature deep drilling, and has the obvious advantages of excellent quality and reasonable price.
Description
Technical field:
The present invention relates to the composition that soil layer in the oil production process or clay creep into usefulness, particularly a kind of not only viscosity reducing effect is good, and does not influence fluid loss, cheap oil drilling slurry viscosity reducer.
Background technology:
Viscosity-depression agent commonly used at present, as chromium-iron lignosulfonate, environmental pollution is serious, as amphoteric ion polymer XY-27, cost an arm and a leg, all stronger to the structure deteriorate of mud system, projecting point is exactly that fluid loss strengthens, cause hole diameter irregular, the contaminated oil gas-bearing formation can also cause accidents such as bag bores, caves in.
Summary of the invention:
It is good to the purpose of this invention is to provide a kind of not only viscosity reducing effect, and does not influence fluid loss, cheap oil drilling slurry viscosity reducer.
Technical scheme of the present invention is finished as follows, it includes following components by weight percent: 6.9 parts of acrylic tankage, 4.2 parts in sodium hydroxide, 8 parts in formic acid, 17 parts in 30% hydrogen peroxide, 64 parts in water, its preparation method is: (1) joins the acrylic tankage in the reactor for 6.9 parts earlier, add 64 parts of entry more successively, 4.2 parts in sodium hydroxide, (2) with steam the reactor internal heating is extremely seethed with excitement, hydrolysis 5 hours, (3) be cooled to after the hydrolysis below 50 ℃ and begin to stir after with 8 parts in formic acid pH value being transferred to neutrality, in stirring, slowly add 17 parts of hydrogen peroxide, be discharged in the stock chest after waiting not have bubble, (4) material in the stock chest is dried under 100 ℃ of temperature, be ground into powder again or particle gets final product.Product of the present invention has high temperature resistance, anti-salt property, applicable to various water-base drilling fluids and well cementation use in the high temperature deep well drilling well, has inexpensive remarkable advantage.
Embodiment:
The present invention has following examples: a kind of preparation method of oil drilling slurry viscosity reducer: (1) puts into reactor with acrylic tankage 6500 grams earlier, adds 64000 gram water purification and 4200 gram sodium hydroxide more successively; (2) with steam the reactor internal heating is extremely seethed with excitement then, be hydrolyzed 5 hours; (3) be cooled to after the hydrolysis below 50 ℃ with 8000 gram formic acid and adjust the pH value of solution to neutral, begin then to stir, in stirring, slowly add hydrogen peroxide 17000 grams, be discharged in the stock chest behind the no bubble in the question response still, (4) material in the stock chest is dried under 100 ℃ of temperature, being ground into powder or particle then, promptly is this viscosity-depression agent.After testing, this product outward appearance is canescence or yellow particle or powder, fineness be 10 mesh sieve throughputs greater than 95%, moisture≤10, water-insoluble≤2%; PH value (1% aqueous solution) is 7-9, apparent viscosity (10% aqueous solution)≤20mpa.S; Viscosity break ratio 〉=80% thinks that this agent is a kind of drilling fluid thinner of high-temperature resisting and salt-resisting cheaply, is applicable to various water-base drilling fluids, can be used in the high temperature deep well drilling fluid.General consumption is the 0.1-1% of mud.
