Embodiment 1

[0049] (1) Dissolve 100g of epoxy resin (commercially purchased from Langfang Nuoerxin Chemical Co., Ltd., brand E-44, epoxy value 0.44mol / 100g, hydroxyl value 0.088mol / 100g) in 50g toluene, with stirring The temperature was raised to 50°C, then 15.3g of toluene diisocyanate was added, and the reaction was stirred at this temperature for 2 hours; then 18.7g of polysiloxane (commercially purchased from Dongguan Aolite Silicone Material Co., Ltd., hydroxyl value 8% by weight), after continuing the reaction for 2 hours, the temperature was raised to 70° C. for another 1 hour. The obtained mixture was evaporated under reduced pressure in a rotary evaporator at a temperature of 60° C. to remove toluene, thereby obtaining the hydrophobic resin composition of the present invention.

[0050] (2) Mix 100g of the hydrophobic resin composition obtained in step (1) with 2000g of raw sand (commercially purchased from Jinshengyuan Proppant Co., Ltd., Qingtongxia City, with a particle size o...

[0054] (1) Dissolve 100g of epoxy resin (commercially purchased from Langfang Nuoerxin Chemical Co., Ltd., brand E-31, epoxy value 0.31mol / 100g, hydroxyl value 0.166mol / 100g) in 50g toluene, with stirring The temperature was raised to 50°C, then 27.6g of cyclohexyl diisocyanate was added, and the reaction was stirred at this temperature for 2 hours; then 35.3g of polysiloxane (commercially purchased from Dongguan Aolite Silicone Material Co., Ltd., hydroxyl value 8% by weight), after continuing the reaction for 2 hours, the obtained mixture was evaporated under reduced pressure in a rotary evaporator at a temperature of 60° C. to remove toluene, thereby obtaining the hydrophobic resin composition of the present invention.

[0055] (2) Mix 160g of the hydrophobic resin composition obtained in step (1) with 2000g of raw sand (commercially purchased from Qingtongxia Jinshengyuan Proppant Co., Ltd., with a particle size of 30-50 mesh) and stir for 2 minutes, then add 20g Diaminodi...

Embodiment 3

[0057](1) Dissolve 100g of epoxy resin (commercially purchased from Langfang Nuoerxin Chemical Co., Ltd., brand E-51, epoxy value 0.51mol / 100g, hydroxyl value 0.046mol / 100g) in 50g toluene, with stirring The temperature was raised to 50° C., then 10.2 g of isophorone diisocyanate was added, and the reaction was stirred at this temperature for 2 hours; then 9.8 g of polysiloxane (commercially purchased from Dongguan Aolite Silicone Material Co., Ltd., The hydroxyl value was 8% by weight), and after continuing the reaction for 2 hours, the temperature was raised to 70° C. and the reaction was continued for 1 hour. The obtained mixture was evaporated under reduced pressure in a rotary evaporator at a temperature of 60° C. to remove toluene, thereby obtaining the hydrophobic resin composition of the present invention.

[0058] (2) Mix 100g of the hydrophobic resin composition obtained in step (1) with 2000g of raw sand (commercially purchased from Jinshengyuan Proppant Co., Ltd., ...

Abstract

The invention provides a fracturing propping agent and a preparation method thereof, the fracturing propping agent is prepared by curing a mixture containing aggregate particles and a laminating adhesive, the laminating adhesive is a hydrophobic resin composition containing epoxy resin and polysiloxane, the polysiloxane is connected with at least part of the epoxy resin by a coupling agent, 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 polysiloxane by a second coupling part, and the fracturing propping agent has high water plugging capability and high crushing resistant strength.

Description

technical field [0001] The invention relates to a fracturing proppant and a preparation method of the 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 temperature above 800°C) and quartz sand, and their water blocking ability needs to be further improved.
