The present invention compares with existing plugging agent, and tool has the following advantages or beneficial effect:
1, have good temperature resistance, fixed ability, temperature resistance can reach 180-200 ℃;
2, Heat stability is good, intensity is high, and validity period is long, and plugging effect is good.
3, have certain swollen performance that rises, volume does not dwindle, and does not go out free water,
4, under hot conditions, be difficult for degraded, indeformable, can keep original intensity, can guarantee leak stopping success ratio.
5, compatibleness is good, has good mobility under hot conditions, can be trapped in high temperature leakage channel, has avoided duplicating leakage under hot conditions.
6, be applicable to high temperature deep well and geothermal well blocking construction,
7, nontoxic, environmentally safe, operational safety, can guarantee continuous construction, can not cause down-hole complex accident.
