Crack plugging consolidation agent, preparation method and crack plugging method
The invention discloses a crack plugging consolidation agent, a preparation method and a crack plugging method, and the consolidation agent comprises the following raw material components in percentage by mass: 76-82% of oil well cement, 8-12% of superfine cement, 5-8% of silica fume and 4-8% of micron-sized plugging agent. The consolidation agent is mixed with water to prepare plugging slurry, then the plugging slurry is injected into a well section needing to be plugged, and the plugging slurry can be squeezed into micro cracks from large cracks to be cemented and solidified to form a high-strength plugging belt. The crack plugging consolidation agent has the advantages of low production cost and good crack plugging effect.
本发明公开了一种裂缝封堵固结剂、制备方法及裂缝封堵的方法，按照质量百分比计，固结剂的原料组分包括：76～82％的油井水泥、8～12％的超细水泥、5～8％的微硅粉和4～8％的微米级堵漏剂。本发明中的固结剂与水混合，配制出封堵浆，然后注入需封堵井段，封堵浆可由较大裂缝挤入微细裂缝，进行胶结固化，形成高强度封堵带。并且本发明中的裂缝封堵固结剂具有生产成本低和裂缝封堵效果好的优点。
