摘要
A gel plugging slurry for well drilling, comprising water, special gel, bridging material, linking material, and packing material, wherein based on 100 parts by weight of the water, the amount of the special gel is 1-15 parts by weight, the amount of the bridging material is 8-20 parts by weight, the amount of the linking material is 20-40 parts by weight, and the amount of the packing material is 25-45 parts by weight. The gel slug plugging method including simple operation and low requirement for ambient environment; besides, the bridging material, linking material and packing material in the gel plugging slurry form stable structures in the gel, and thereby the gel plugging effect can be improved effectively.
