Embodiment 1
[0060] The ratio of raw materials in this embodiment is 30% of oilfield sludge, 40% of river sand, 26% of cement, and 4% of curing agent.
[0061] Wherein, the curing agent is mixed with the raw materials in the following weight ratio:
[0062] Sulfoaluminate: 22% Calcium Stearate: 5%
[0063] Calcium Chloride: 20% Calcium Acetate: 0
[0064] Fluorite: 0 Gelatin: 5%

[0069] The production method is:
[0070] After mixing oilfield sludge, river sand, cement, and curing agent evenly, put the slurry material into a mold, apply a pressure of 550KN on a press to form, demould, and dry to make a finished product.
[0071] According to the buildin...
Embodiment 2
[0080] The ratio of raw materials in this embodiment is 35% of oilfield sludge, 20% of river sand, 20% of cement, 24% of fly ash, and 1% of curing agent.
[0081] Wherein, the curing agent is mixed with the raw materials in the following weight ratio:
[0082] Sulfoaluminate: 15% Calcium Stearate: 2%
[0083] Calcium Chloride: 10% Calcium Acetate: 15%
[0084] Fluorite: 10% Gelatin: 9%
[0086] Acrylic 4%
[0087] After oilfield sludge, river sand, cement, fly ash, and curing agent are mixed evenly, the slurry material is loaded into a mold, pressed on a press with a pressure of 650KN, demolded, and dried to make a finished product.
[0088] The performance test results are: the average 28-day compressive strength is 16.66Mpa, and the 28-day flexural strength is 5.65Mpa. Its mechanical properties can still meet the relevant national standards. Other properties are substantially the same as in Example 1.
Embodiment 3
[0090] The ratio of raw materials in this embodiment is 55% of oilfield sludge, 20% of river sand, 18% of cement, and 7% of curing agent.
[0091] Wherein, the proportioning of curing agent is:
[0092] Sulfoaluminate: 20% Calcium Stearate: 5%
[0093] Calcium Chloride: 15% Calcium Acetate: 10%
[0094] Fluorite: 0 Gelatin: 5%
[0096] Acrylic resin 0 Monoethylene glycol 5%
[0097] Sucrose 5%
[0098] Core material: 10%
[0099] Wherein the core material is composed of the following raw materials in weight percentage: CaO MgO Fe 2 o 3 SiO 2 al 2 o 3 al 2 (SO 4 ) 4 Na 2 CO 3 FeSO 4 MgSO 4 5 5 6 15 12 20 20 7 10
[0100] The production method is as follows: After mixing oilfield sludge, river sand, cement, fly ash, and curing agent evenly, the slurry material is loaded into a mold, pressed on a press with a pressure of 650KN, demolded, and dried to make a finished product .
[0101] The performance test results are: ...
