Compound method: above-mentioned substance adds in reactor successively by its component and content, stirs mixed 5-6 hour, then adds in moisture eliminator, after its drying, be ground into the pressed powder goods of 0.01-0.3mm under normal pressure, 50-65 DEG C condition.
The present invention's tool compared with existing plugging agent has the following advantages or beneficial effect:
1, the leak stopping slurry of high density performance can be made, and there is fine ultimate compression strength, be applied to leak stopping in deep well high pressure stratum;
2, have fine shutoff coagulability, solid content is high, and can hold a large amount of plugging agents, sealing ratiod is high;
3, under high-density state, there is good rheological, easily pump into, leakage channel depths can be entered, improve shutoff bearing capacity;
4, the leakage stratum blocking construction be particularly suitable for high pressure, not only leaking but also gush;
5, construction technology safely and fast, harmless to valve member, can guarantee sequential production;
6, nontoxic, harmless, pollution-free, easy and safe to operate.
