Embodiment 1
[0021] Embodiment 1: The well wall reinforcement working fluid, the raw materials are calculated in parts by weight, including 30 to 60 parts of resin material, 30 to 60 parts of curing agent, 5 to 10 parts of flexible material and 5 to 10 parts of weighting material , according to the following steps: the first step, at room temperature, add the required amount of resin material, under the condition of 0°C to 45°C, control the stirring speed from 600rpm to 1200rpm, add the required amount of curing agent to the resin material, stir After 2h to 5h, the first mixture is obtained; in the second step, under the condition of 0°C to 45°C, the stirring speed is controlled from 600rpm to 1200rpm, and the required amount of flexible material is added to the first mixture, and after stirring for 30min to 60min, the second mixture is obtained. The second mixture; the third step, under the condition of 0°C to 45°C, control the stirring speed from 600rpm to 1200rpm, add the required amount...
Embodiment 2
[0022] Embodiment 2: The well wall reinforcement working fluid, the raw materials are calculated in parts by weight, including 30 or 60 parts of resin material, 30 or 60 parts of curing agent, 5 or 10 parts of flexible material and 5 or 10 parts of weighting material , according to the following steps: the first step, at room temperature, add the required amount of resin material, under the condition of 0°C or 45°C, control the stirring speed at 600rpm or 1200rpm, add the required amount of curing agent into the resin material, stir After 2h or 5h, the first mixture is obtained; in the second step, at 0°C or 45°C, the stirring speed is controlled at 600rpm or 1200rpm, and the required amount of flexible material is added to the first mixture, and after stirring for 30min or 60min, the second mixture is obtained. The second mixture; the third step, at 0°C or 45°C, control the stirring speed at 600rpm or 1200rpm, add the required amount of weighting material to the second mixture...
Embodiment 3
[0025] Embodiment 3: As the optimization of the foregoing embodiment, the resin material is bisphenol A with a mass percentage concentration of 40% to 70%, and two of dioxirane and butanediol with a mass percentage concentration of 5% to 15%. more than one species. The resin material has strong compressive strength and toughness after being solidified and formed. As the main body of the well wall reinforcement working fluid of the present invention, it ensures that the well wall reinforcement working fluid has better compressive strength and toughness.
