Embodiment 1
[0024] The dehydration and dehydration treatment method of waste drilling mud:
[0025] (1) Preparation of oxidative cationic gel breaking system
[0026] At room temperature, add Al to the beaker 2 (SO 4 ) 3 (100g, 0.29mol), stirred in 300ml deionized water to dissolve it, then slowly added concentrated H 2 SO 4 (100g) and NaClO (20g), stirred and placed.
[0027] (2) Preparation of mud curing agent
[0028] At room temperature, sequentially weigh Al into the reactor 2 o 3 (15g, 0.147mol) and SiO 2 (10g, 0.167mol), add 100ml of water and stir evenly, place in a water bath at 60°C, stir for 10min, then add Ca(OH) 2 (50g, 0.676mol), stirred rapidly for 30min and left.
[0029] (3) Waste mud gel breaking and solidification treatment
[0030] Take 7500g of waste drilling mud in the container, first quickly add 296g of the oxidized cationic gel breaker prepared in step 1, stir evenly, then add 5g of 1‰ highly charged cationic organic flocculant, stir well, and finally a...
Embodiment 2
[0032] (1) Preparation of acidic cationic gel breaking system
[0033] At room temperature, add Al to the beaker 2 (SO 4 ) 3 (100g, 0.29mol), stirred in 300ml deionized water to dissolve it, then slowly added concentrated H 2 SO 4 (100g) and H 2 o 2 (15g), stirred and placed.
[0034] (2) Preparation of mud curing agent
[0035] At room temperature, sequentially weigh Al into the reactor 2 o 3 (15g, 0.147mol) and SiO 2 (10g, 0.167mol), add 100ml of water and stir evenly, place in a water bath at 60°C, stir for 10min, then add Ca(OH) 2 (50g, 0.676mol), stirred rapidly for 30min and left.
[0036] (3) Waste mud gel breaking and solidification treatment
[0037] Take 7500g of waste drilling mud in the container, first quickly add 296g of the oxidized cationic gel breaker prepared in step 1, stir evenly, then add 5g of 1‰ highly charged cationic organic flocculant, stir well, and finally add 242g of step 2 The prepared mud curing agent was stirred for 10 minutes, and ...
Embodiment 3
[0039] (1) Preparation of acidic cationic gel breaking system
[0040] At room temperature, add Al to the beaker 2 (SO 4 ) 3 (100g, 0.29mol), stirred in 300ml deionized water to dissolve it, then slowly added concentrated H 2 SO 4 (100g) and NaClO (20g), stirred and placed.
[0041] (2) Preparation of mud curing agent
[0042] At room temperature, sequentially weigh Al into the reactor 2 o 3 (15g, 0.147mol) and SiO 2 (10g, 0.167mol), add 100ml of water and stir evenly, place in a water bath at 60°C, stir for 10min, then add CaO (50g, 0.893mol), stir rapidly for 30min and let it stand.
[0043] (3) Waste mud gel breaking and solidification treatment
[0044] Take 7500g of waste drilling mud in the container, first quickly add 296g of the oxidized cationic gel breaker prepared in step 1, stir evenly, then add 5g of 1‰ highly charged cationic organic flocculant, stir well, and finally add 242g of step 2 The prepared mud curing agent was stirred for 10 minutes, and after...
