Abstract
A resin slurry for a fractured-vuggy formation and the preparation and use thereof, which belong to the field of drilling fluid lost circulation control. The resin slurry plugging system is composed of the following raw materials in mass percentage: 20%-40% of composite resin plugging agent, 0.5%-5.0% of consolidating agent, 0.5%-5.0% of flow pattern regulator, 0.3%-1.2% of cross-linking agent, 0.3%-1.2% of retarder, 3%-12% of filling agent, and the balance of water. The plugging system has a certain fluidity under low-temperature conditions, is easy to be injected into the formation, and can fill a lose channel of a fractured-vuggy reservoir. The consolidating time of the plugging system is controllable, and the construction conditions are safe. The plugging system forms a three-dimensional cross-linked network structure consolidation after cross-linking and consolidating under high-temperature conditions of the formation.
