Embodiment 1
[0037] A method for preparing sintered bricks from water-based drilling cuttings, comprising the steps of:
[0038] (1) Water-based drilling cuttings are automatically added into the sinking continuous reactor, and 0.5% by mass modifier is added to the reactor for full reaction to obtain reformed solid waste; (2) the reformed The solid waste is transported to the brick factory, stacked and dried naturally for 3 days in the raw material area of the brick factory, and then the modified solid waste is mixed with internal combustion materials and shale soil at a weight ratio of 3:1:3, crushed, and sieved. Obtain the mixture; (3) transfer the mixture to the brick mixing mixing system, and then add 10% by mass of tap water, drilling waste water, fracturing flowback water and gas production and oil production waste water, or a mixture of at least two, Stir, shape, and make adobe; (4) Dry the adobe for 48 hours and send it to a brick kiln, sinter at 1100°C for 10 hours, then cool an...
Embodiment 2
[0040] A method for preparing sintered bricks from water-based drilling cuttings, comprising the steps of:
[0041] (1) Water-based drilling cuttings are automatically added to the sinking continuous reactor, and 2.0% by mass of a modifier is added to the reactor for full reaction to obtain reformed solid waste; (2) the reformed The solid waste is transported to the brick factory, stacked and dried naturally for 7 days in the raw material area of the brick factory, and then the modified solid waste is mixed with internal combustion materials and shale soil at a weight ratio of 60:8:52, crushed, and sieved. Obtain the mixture; (3) transfer the mixture to the brick mixing system, and then add 15% by mass of tap water, drilling waste water, fracturing flowback water and gas and oil recovery waste water, or a mixture of at least two, Stir, shape, and make adobe; (4) Dry the adobe for 60 hours and send it to a brick kiln, sinter at 900°C for 15 hours, then cool and leave the kiln t...
Embodiment 3
[0043] A method for preparing sintered bricks from water-based drilling cuttings, comprising the steps of:
[0044] (1) Water-based drilling cuttings are automatically added into the sinking continuous reactor, and 1.0% of the mass percent modifier is added to the reactor for full reaction to obtain the reformed solid waste; (2) the modified solid waste The solid waste is transported to the brick factory, stacked and dried naturally for 5 days in the raw material area of the brick factory, and then the modified solid waste is mixed with internal combustion materials and shale soil at a weight ratio of 45:9:40, crushed, and sieved. Obtain the mixture; (3) transfer the mixture to the mixing system for brick making, then add a mixture of 12% by mass of tap water and drilling waste water, stir, shape, and make adobe; (4) dry the adobe for 55 hours and send it into The brick kiln is sintered at 1000°C for 12 hours, then cooled and discharged from the kiln to obtain the finished s...
