This product is specifically developed to address reservoir leakage during well-cleaning, sand flushing, or workover operations (such as unblocking or sand control) in the oil extraction process. This series of temporary plugging agents is a strong gel system, primarily composed of thickening agents, bridging agents, dispersants, crosslinkers, and gel breakers. It features high blocking strength, adjustable gelation and freezing times, complete self-breaking properties, minimal formation contamination, a simple on-site preparation process, and reliable, safe construction. It is suitable for plugging operations in lowpressure inclined, vertical, or horizontal wells with unclear leakage layers and leakage rates between 5-25 cubic meters per hour.
