Embodiment 1
[0036] This embodiment is a formula suitable for the plugging material used in summer.
[0037] Curing component:
[0038] Quick-setting cement 19.7wt%
[0039] Lime 10.0wt%
[0040] Polyacrylamide powder 0.3wt%;
[0041] Plugging skeleton components:
[0042] Coal powder 65.0wt%
[0043] Talc 5.0wt%;
[0044] The amount of the adhesive is then determined according to the ratio of the total solid amount of the above curing component and the plugging skeleton component: the amount of the adhesive = 55%: 45%;
[0045] The composition of described adhesive component is:
[0046] Carboxymethylcellulose 6.0wt%
[0047] Polyvinyl alcohol 2.0wt%
[0048] Water-Alcohol 92.0wt%
Embodiment 2
[0050] This embodiment is a formula suitable for the plugging material used in spring.
[0051] Curing component:
[0052] Quick-setting cement 25.0wt%
[0053] Lime 10.0wt%
[0054] Plugging skeleton components:
[0055] Coal powder 60.0wt%
[0056] Talc 5.0wt%;
[0057] The amount of the adhesive is then determined according to the ratio of the total solid amount of the above curing component and the plugging skeleton component: the amount of the adhesive = 55%: 45%;
[0058] The composition of described adhesive component is:
[0059] Carboxymethylcellulose 6.0wt%
[0060] Polyacrylamide 0.3wt%
[0061] Polyvinyl alcohol 1.0wt%
[0062] Water-Alcohol 92.7wt%
Embodiment 3
[0064] This example is for reference figure 1 A specific embodiment of preparing adhesive:
[0065] (1) Preparation of polyacrylamide-organic bentonite emulsion: first dissolve polyacrylamide in water to make a 2% solution, then add bentonite and stir evenly to form a white emulsion.
[0066] (2) Preparation of adhesive: add pure water to the reactor, heat to boiling, add polyvinyl alcohol while stirring, wait for the polyvinyl alcohol to dissolve, add carboxymethyl cellulose and alcohol, keep below 85°C to continue the reaction To form a transparent solution, add polyacrylamide-organic bentonite emulsion, stir evenly, cool down and discharge to obtain an adhesive. The conversion ratio of each component is
[0067] Solid carboxymethyl cellulose 6.0wt%
[0068] Solid polyacrylamide 0.3wt%
[0069] Solid polyvinyl alcohol 1.0wt%
[0070] Water-Alcohol 92.7wt%
