Embodiment 1

[0030] The preparation method of nano lauryl methacrylate homopolymer, the steps are as follows:

[0031] (1) Measure 30 ml of methyl methacrylate, add it to 100 ml of water, blow in nitrogen, add 0.3 g of benzoyl peroxide, and heat to 100°C for 5 hours.

[0032] (2) The obtained reaction solution was centrifuged or evaporated at 50°C to remove water, and then vacuum-dried at 60°C for 12 hours.

[0033] (3) Weigh 5 grams of nano-methyl methacrylate powder and 5 grams of dodecanol in 50 ml of dimethylformamide, add 1% sodium hydroxide and react at 180°C for 7 hours. Cool to room temperature.

[0034] (4) Add the cooled solution to a certain amount of water, filter, and then vacuum-dry at 80°C for 12h.

Embodiment 2

[0035] Embodiment 2: the preparation method of nano-tetradecyl methacrylate homopolymer, step is the same as example 1, difference is to replace lauryl alcohol with myristyl alcohol.

Embodiment 3

[0036] Embodiment 3: the preparation method of nano-hexadecyl methacrylate homopolymer, step is the same as example 1, difference is to replace lauryl alcohol with cetyl alcohol.

Abstract

The invention discloses a thickened oil nanometer viscosity reducer and a preparation method thereof and belongs to the technical field of preparation of macromolecule nanometer materials. The nanometer viscosity reducer comprises nanometer acrylic high-carbon ester and nanometer divinylbenzene-acrylic high-carbon ester. The preparation method comprises the steps: (1) preparing nanometer acrylic short-chain ester or the nanometer divinylbenzene-acrylic high-carbon ester, (2) processing a nanometer acrylic short-chain ester reaction solution to obtain nanometer acrylic short-chain ester powder, (3) preparing the nanometer acrylic high-carbon ester and (4) processing the nanometer acrylic high-carbon ester. The nanometer viscosity reducer is good viscosity reducing effect, wide in application range, simple in synthesis and low in cost. An experiment proves that the net viscosity reducing rate of the nanometer viscosity reducer to Daqing crude oil and Shengli crude oil can reach to more than 45%.

Description

[0001] technical field [0002] The invention relates to the design and preparation method of a nano-viscosity reducer for heavy oil, and belongs to the technical field of polymer nano-material preparation. Background technique [0003] Due to the dwindling oil resources and the declining production of conventional crude oil, the abundant heavy oil has aroused widespread concern. With the continuous development of heavy oil resources, heavy oil transportation has become a major technical problem. [0004] At present, it is considered the most economical method to transport heavy oil by adding fluidity improvers. Therefore, the research on viscosity reducer for heavy oil has become a hot spot in petrochemical industry. Because nanomaterials have the characteristics of small size, large specific surface area and good adsorption, nanomaterials are continuously used in petroleum viscosity reducers. But until now, nanometer high-carbon acrylate, divinylbenzene-acrylic high-car...
