Severe Loss Plugging Agent
Catalog NO.: AIMRSE-CHM-ADD-096 Manufacturer PN: CHM-PLG-SEV
• The leakage control slurry can be directly pumped through the drill pipe and drill bit without tripping, and does not alter the rheological properties of the drilling fluid system; it has a maximum pressure resistance of up to 20 MPa and a temperature resistance exceeding 200°C. “One-Bag Leakage Control Agent” can be used in reservoirs, with a permeability recovery rate greater than 95%.
Suitable for various loss scenarios, significantly enhances formation pressure-holding capacity. Compatible with drilling fluids, workover fluids, and completion fluids across all drilling fluid systems, including water-based, oil-based, and synthetic-based.
The high-efficiency leak sealing agent is a blend of ultrafine mica flakes, wood fibers, chemical fibers, inorganic particles, and specially formulated surfactants. It functions as a dual-membrane pressure-bearing wall stabilizer, comprising an inert material with a physical sealing membrane and an active chemical barrier membrane. This significantly enhances formation pressure resistance while restoring and maintaining wellbore integrity. This specialized sealing agent is particularly effective for addressing leaks, localized losses, severe losses, and even non-return losses occurring in induced fractures, natural fractures, faults, and small cavities. It exhibits a maximum pressure-bearing capacity of 20 MPa and temperature resistance exceeding 200°C. Compatible with all drilling mud systems, its unique feature is maintaining the inherent rheological properties of the mud.
