Abstract

The invention provides a hydrophobic resin composition and a preparation method and application thereof, the hydrophobic resin composition contains epoxy resin and a fluorinated compound, the fluorinated compound is connected with at least part of the epoxy resin by a coupling agent, the coupling agent has at least two isocyanate groups, at least part of the epoxy resin has hydroxyls, the fluorinated compound has groups capable of providing protons, one end of the coupling agent is in covalent linkage with at least part of the epoxy resin by a first coupling part, the other end of the coupling agent is in covalent linkage with the fluorinated compound by a second coupling part, the first coupling part is formed by the isocyanate groups in the coupling agent and the hydroxyls in the epoxy resin, and the second coupling part is formed by the isocyanate groups in the coupling agent and the groups capable of providing the protons in the fluorinated compound. A fracturing propping agent prepared by mixing of the hydrophobic resin composition and roughing sand and then solidification not only has high water plugging capability, but also has high crushing resistant strength.

Description

technical field [0001] The invention relates to a hydrophobic resin composition and a preparation method thereof, and further relates to the application of the hydrophobic resin composition in preparing a fracturing proppant. Background technique [0002] During the exploitation of oil and natural gas, the high closure pressure and low permeability ore deposits are subjected to fracturing treatment, so that the oil-gas-bearing rock formations are cracked, and oil and gas are collected from the channels formed by the fractures. The fracturing proppant enters the formation along with the high-pressure solution to fill in In the cracks of the rock formation, it plays a role in supporting the cracks from closing due to stress release, so as to maintain high conductivity, make oil and gas unblocked, and increase oil and gas production. [0003] The existing fracturing proppants are mainly ceramsite (generally made of bauxite as the main raw material and sintered at a high tempera...
