Embodiment 1

[0021] Accurately weigh the raw materials (Kg): Kubuqi Desert Sand 150 with a sand particle size of 0.106mm-3.35mm, water-based bisphenol A epoxy resin 4.5, water-based epoxy fatty amine curing agent 0.5, and water 15.

[0022] The preparation method of the novel coated proppant consists of the following steps:

[0023] (a) Pour the Kubuqi Desert sand into the sand mixer;

[0024] (b) Mix the metered resin and curing agent, add the solvent, stir evenly and fully dissolve;

[0025] (c) Add the mixture of resin binder and curing agent to the desert sand and stir for 50-100s to make the binder fully cover the desert sand aggregate; spread it flat on a horizontal surface and fully cure it for 24 hours;

[0026] (d) Smash;

[0027] (e) Screening and packaging.

Embodiment 2

[0029] Accurately weigh the raw materials (Kg): Kubuqi Desert Sand 180 with a sand particle size of 0.106mm-3.35mm, water-based bisphenol A epoxy resin 5, water-based epoxy fatty amine curing agent 0.7, and water 20.

[0030] The preparation method of the film-coated modified proppant consists of the following steps:

[0031] (a) Pour the Kubuqi Desert sand into the sand mixer;

[0032] (b) Mix the metered resin and curing agent, add the solvent, stir evenly and fully dissolve;

[0033] (c) Add the mixture of resin binder and curing agent to the desert sand and stir for 50-100s to make the binder fully cover the desert sand aggregate. Spread flat on a horizontal surface and fully solidify for 24h;

[0034] (d) Smash;

[0035] (e) Screening and packaging.

Embodiment 3

[0037] Accurately weigh the raw materials (Kg): Kubuqi Desert Sand 200 with a sand particle size of 0.106mm-3.35mm, water-based bisphenol A epoxy resin 14, water-based epoxy fatty amine curing agent 5, water 25.

[0038] The preparation method of the novel coated proppant consists of the following steps:

[0039] (a) Pour the Kubuqi Desert sand into the sand mixer;

[0040] (b) Mix the metered resin and curing agent, add the solvent, stir evenly and fully dissolve;

[0041] (c) Add the mixture of resin binder and curing agent to the desert sand and stir for 50-100s to make the binder fully cover the desert sand aggregate. Spread flat on a horizontal surface and fully solidify for 24h;

[0042] (d) Smash;

[0043] (e) Screening and packaging.

Abstract

The invention discloses a tectorial membrane proppant as well as a preparation method and the application thereof. The tectorial membrane proppant is characterized by consisting of the following components in part by weight: 150 to 250 parts of Kubuqi desert sand, 2 to 20 parts of resin binder and curing agent and 5 to 50 parts of water, wherein the using amount of the curing agent is 10 to 50 percent of the weight of the resin binder and the curing agent; the resin is waterborne epoxy bisphenol A resin; and the curing agent is waterborne epoxy fatty amine curing agent. The tectorial membrane proppant is prepared by stirring the components uniformly, completely curing, dispersing uniformly and sieving. The tectorial membrane proppant is applied to the field of fracturing exploitation of petroleum and natural gas oil. The invention has the characteristics that the production process is simple; the product has low relative density, high strength, low breakage rate and high roundness, sphericity and chemical inertness; and pollution in the preparation process is avoided. The invention is widely applied to fracturing of oil field and gas field, so that the using amount of fracturing liquid is reduced, the flow guide ability of crack is improved, the fracturing useful life is prolonged, the oil yield is facilitated, and important significance of solving problem about exploitation of low-permeability oil field is achieved.

Description

Technical field [0001] The invention relates to a film-coated proppant used in the field of oil and natural gas oil well fracturing and exploitation, and a preparation method and application thereof. Background technique [0002] Petroleum fracturing proppants are mainly used for deep well exploitation of oil and natural gas, especially materials that must be used in the exploitation of oil and gas with a well depth of more than 2,000 meters. High-strength proppants are filled into the cracks of low-permeability deposits for high Closed fracturing treatment to support fractures not being closed due to stress release, allowing oil and gas to flow out of the fracture channels, thereby maintaining high oil and gas conductivity, increasing oil and gas production, and extending oil and gas well services Years, improve the economic benefits of oil and gas production. [0003] At present, the proppants used in fracturing processes at home and abroad are mainly quartz sand and ceramsite. ...
