Embodiment approach

[0065] The apparent viscosity of the system was measured with a DV2TLV viscometer produced by Brookfield, and the test temperature was 50°C. According to an embodiment of the present application, the experimental procedure is as follows:

[0066] Step (1): add the purchased industrial-grade coupled montmorillonite nanomaterials, organic hydrophilic monomers, and organic hydrophobic monomers into a round-bottomed flask, add an appropriate amount of water, stir and dissolve, and pass nitrogen to remove oxygen;

[0067] Step (2): adding the initiator into the beaker, adding an appropriate amount of water, stirring and dissolving, and deoxidizing with nitrogen;

[0068] Step (3): the round-bottomed flask in (1) is placed in an oil bath, mechanically stirred and heated;

[0069] Step (4): add the solution in step (2) into the dropping funnel on the round-bottomed flask in step (3), and drop the solution in step (2) into the round-bottomed flask in step (3), After heating and reac...

[0093] Example 1 Preparation of 1# hybrid nanomaterials

[0094] Put 5.00 g of coupled montmorillonite nanomaterials, 2.50 g of sodium α-alkenyl sulfonate and 2.50 g of acrylamide (the mass ratio of the two is 1:1) into a round-bottomed flask, add 80 g of water, and stir to mix. Evenly, introduce nitrogen to remove oxygen for 30min, then place in oil bath pot, stir mechanically at 300rpm, and heat to 50°C to obtain mixed solution I; add 0.025g potassium persulfate into the beaker, add 10g water, stir to dissolve, pass into Deoxygenate with nitrogen for 20 minutes to obtain mixed solution II; add mixed solution II to the dropping funnel on the round-bottomed flask, adjust the dropping rate, add dropwise time for 10 minutes, heat to 80°C, and react for 5 hours. The organic-inorganic hybrid nanomaterial was obtained, which was recorded as sample 1#.

Abstract

The invention discloses an organic-inorganic hybrid nano material. The organic-inorganic hybrid nano material is composed of structural units represented by a formula i, a formula ii and a formula iiishown in the specification. The invention also discloses a preparation method of the organic-inorganic hybrid nano material. The emthod comprises the following steps: stirring and heating an aqueoussolution containing the coupled montmorillonite nano material, organic hydrophobic monomer and organic hydrophilic monomer raw materials, adding an initiator, and carrying out free radical polymerization reaction to obtain the organic-inorganic hybrid nano material. The organic hydrophobic monomer is selected from at least one of sodium alpha-olefin sulfonate, sodium oleate, potassium oleate and sodium linoleate; and the organic hydrophilic monomer is selected from at least one of acrylamide and acrylic acid. The preparation method is simple in process, wide in raw material source and suitablefor industrial production, application and popularization. The organic-inorganic hybrid nano material is used as a water-soluble nano viscosity reducer and has an obvious viscosity reduction effect.

Description

technical field [0001] The present application relates to an organic-inorganic hybrid nanomaterial, a preparation method and application thereof, and belongs to the field of viscosity reduction of heavy oil. Background technique [0002] The world's heavy oil resources are extremely rich, and its geological reserves far exceed conventional crude oil. More than 70 heavy oil fields have been discovered in 12 basins in my country, and their resources account for about 25% to 30% of the total oil resources. As the recoverable amount of light crude oil is less and less and the extraction technology continues to improve, the exploitation of heavy oil resources has attracted more and more attention from all over the world. However, high density, high freezing point, high viscosity and difficulty in flowing are the outstanding characteristics of heavy oil resources in my country. Therefore, reducing the viscosity of heavy oil and improving its fluidity are the keys to solving the ...
