Embodiment 1
[0033] A clear water fracturing proppant, comprising aggregates and a coating layer wrapped outside the aggregates, the coating layer is prepared from a resin, a curing agent and a catalyst; the specific mass parts of the above raw materials used are as follows: 100 parts of aggregate, 2 parts of resin, 1.1 parts of curing agent, 0.01 part of catalyst. The aggregate is 20 / 40 quartz sand, the resin is glycerol polymer, the curing agent is toluene diisocyanate, and the catalyst is dibutyltin dilaurate. In this embodiment, the energy spectrum test characteristic of the coating layer is that the atomic ratio of carbon to oxygen is 5:1.
[0034] The clear water fracturing proppant is prepared by the following method: after heating the aggregate to 90°C, add resin and catalyst, and mix and stir; when the temperature drops to 80°C, add curing agent, mix and stir; when the temperature drops to 50°C, leave Pot, get clean water fracturing proppant.
Embodiment 2
[0036] A clear water fracturing proppant, comprising aggregates and a coating layer wrapped outside the aggregates, the coating layer is prepared from a resin, a curing agent and a catalyst; the specific mass parts of the above raw materials used are as follows: 100 parts of aggregate, 2.5 parts of resin, 1.63 parts of curing agent, and 0.015 parts of catalyst. The aggregate is 30 / 50 quartz sand, the resin is propylene glycol polymer, the curing agent isophorone diisocyanate, and the catalyst is tributyltin. In this embodiment, the energy spectrum test characteristic of the coating layer is that the atomic ratio of carbon to oxygen is 6:1.
[0037] The clear water fracturing proppant is prepared by the following method: after heating the aggregate to 100°C, add resin and catalyst, and mix and stir; when the temperature drops to 90°C, add curing agent, mix and stir; Pot, get clean water fracturing proppant.
Embodiment 3
[0039] A clear water fracturing proppant, comprising aggregates and a coating layer wrapped outside the aggregates, the coating layer is prepared from a resin, a curing agent and a catalyst; the specific mass parts of the above raw materials used are as follows: 100 parts of aggregate, 3 parts of resin, 2.3 parts of curing agent, 0.02 parts of catalyst. Among them, 40 / 70 quartz sand is used as the aggregate, propanol polymer is used as the resin, diphenylmethane diisocyanate is used as the curing agent, and lead isooctoate is used as the catalyst. In this embodiment, the energy spectrum test characteristic of the coating layer is that the atomic ratio of carbon to oxygen is 7:1.
[0040] The clear water fracturing proppant is prepared by the following method: after heating the aggregate to 110°C, add resin and catalyst, mix and stir; when the temperature drops to 100°C, add curing agent, mix and stir; when the temperature drops to 70°C, take out Pot, get clean water fracturin...
