Embodiment 1
[0045] This embodiment provides a slow-release tracer proppant, which is prepared through the following steps:
[0046] Measure 0.1g of sodium citrate and 25mL of N,N-dimethylacetamide into a 50mL polytetrafluoroethylene reactor liner, put it in an ultrasonic cleaner, and ultrasonically oscillate for 0.5 hours until the solid drug is completely dissolved , to form a uniform mixed solution, put the reactor liner into a stainless steel sleeve, and then put the reactor into a blast oven at 120°C for 3.5 hours.
[0047] The resulting reaction solution was naturally cooled to room temperature to obtain a blue fluorescent quantum dot solution, and the solution was rotary evaporated to obtain a fluorescent quantum dot solid powder (fluorescent quantum dot preform).
[0048] Weigh 10 g of phenolic resin at 30° C., dissolve it in 30 g of ethanol solution, and dissolve the fluorescent quantum dot powder in the phenolic resin solution, and stir for 1 hour to obtain a mixed solution of fl...
Embodiment 2
[0064] This embodiment provides a slow-release tracer proppant, which is prepared through the following steps:
[0065] Measure 0.1g of urea, 15mL of aniline and 15ml of ethylenediamine into a 50mL polytetrafluoroethylene reactor liner, put it in an ultrasonic cleaner, and ultrasonically oscillate for 0.5 hours until all the solid drugs are dissolved to form a uniform mixed solution. Put the inner tank of the reaction kettle into a stainless steel sleeve, and then put the reaction kettle into a blast oven at 160° C. for 10 hours.
[0066] The resulting reaction solution was naturally cooled to room temperature to obtain a green fluorescent quantum dot solution, and the solution was rotary evaporated to obtain a solid powder.
[0067] Weigh 10 g of phenolic resin at 30° C., dissolve it in 30 g of ethanol solution, and dissolve the fluorescent quantum dot powder in the phenolic resin solution, and stir for 1 hour to obtain a mixed solution of fluorescent quantum dots and resin. ...
Embodiment 3
[0071] This embodiment provides a slow-release tracer proppant, which is prepared through the following steps:
[0072] Measure 0.2g of o-phenylenediamine and 20mL of ethanol in a 50mL polytetrafluoroethylene reactor liner, put it in an ultrasonic cleaner, and oscillate ultrasonically for 0.5 hours. After all the solid drugs are dissolved and a uniform mixed solution is formed, the reaction The inner tank of the kettle was put into a stainless steel jacket, and then the reaction kettle was put into a blast oven at 180° C. for 8 hours.
[0073] The resulting reaction solution was naturally cooled to room temperature to obtain an orange fluorescent quantum dot solution, and the solution was rotary evaporated to obtain a solid powder.
[0074] Weigh 10 g of phenolic resin at 30° C., dissolve it in 30 g of ethanol solution, and dissolve the fluorescent quantum dot powder in the phenolic resin solution, and stir for 1 hour to obtain a mixed solution of fluorescent quantum dots and ...
