• Sdkx-0198 system can be widely used in tertiary oil recovery, profile control and water plugging, plugging micro-cracks
and sealing channeling in chemical flooding, three-high plugging and sealing channeling after multiple rounds of heavy oil
flooding, profile control and water plugging in three-high and three-high permeable heavy oil fields. Especially suitable for
horizontal well subsection water plugging, oil well, gas well water plugging channeling and conventional measures.
• Sdkx-0198 system injection process; Agent A dilution slug — “Displacement water –” Agent B — “injection well injection (three
days of pumping oil well).
•For sdKX-0198 system, if large fractures are blocked or fractured without closure, three-section plug can be used to block
large channeling layers in oil and gas Wells; Pre-slug (pre-crosslinked soft and hard large particles are injected first, and
the recommended pressure is increased by 0.8-1.5mpa. Then inject slug A and B) — “SDKX-0198 system A, liquid slug –”
replacement liquid — “B, liquid slug –” sealing material slug.
