Embodiment 1
[0036] This embodiment provides a water-controlling low-temperature curing resin-coated sand sand control particle, and its raw material composition includes: proppant quartz sand, thermosetting phenolic resin liquid and one-component polyurethane waterproof coating; proppant quartz sand, thermosetting phenolic resin liquid, The mass ratio of one-component polyurethane waterproof coating is 100:5.0:0.5. Among them, the performance index of the quartz sand meets the relevant requirements of SY / T5108-2006 (fracturing proppant performance index and test recommended practice), and its particle size is 0.45mm-0.8mm.
[0037] The preparation method of the water-controlling low-temperature curing resin-coated sand sand-control particles of this embodiment comprises the following steps:
[0038] Heat the quartz sand to 120°C in a high-temperature drum heating furnace; then take out the quartz sand at 120°C and put it into the sand mixer; then add thermosetting phenolic resin liquid an...

[0040] This embodiment provides a water-controlling low-temperature curing resin-coated sand sand-control particle, and its raw material composition includes: 200kg of low-density ceramsite proppant, 0.4kg of KH550 silane coupling agent, 8kg of thermosetting phenolic resin solution and one-component polyurethane waterproof Paint 1kg. Among them, the performance index of the low-density ceramsite proppant meets the relevant requirements of SY / T5108-2006 (fracturing proppant performance index and test recommended practice), and its particle size is 0.5mm-0.8mm.
[0041] The preparation method of the water-controlling low-temperature curing resin-coated sand sand-control particles of this embodiment comprises the following steps:
[0042] Heat the low-density ceramsite proppant to 120°C in a high-temperature drum heating furnace; then take out the low-density ceramsite proppant at 120°C and put it into the sand mixer; add KH550 silane coupling agent, and then add thermosetting ph...
Embodiment 3
[0045] This embodiment provides a sand control method using the water-controlling low-temperature curing resin-coated sand sand control particles of Example 1. The depth of the construction well section is 778.2m-800m, the effective thickness of the oil layer is 13.7m, and there are 4 layers in total.
[0046] The sand control method comprises the following steps:
[0047] Inject 40m3 of pre-fluid into the formation to be treated through the ground pump unit to clean and press the formation;
[0048] After the pressure is stable, add 15t of the water-controlling low-temperature curing resin-coated sand sand-control particles and the sand-carrying liquid mixture of Example 1, the sand ratio is 10%-30%, and 10-12t of hydrochloric acid with a mass concentration of 3%;
[0049] Replace the tubing, then shut down the well and release the pressure for 48 hours, then use hot sewage to flush out or drill out the resin sand plug in the wellbore, and then it can be put into production....
