Product Introduction
Inorganic plugging adjustment is a new type of plugging adjustment system with technical indicators that meet industry standards. The solidification of the system relies on multiple mechanisms such as inorganic component hydration consolidation and aggregation expansion. It has good universality and scalability, a wide temperature range, strong selectivity, strong impact resistance of the solidified body, and high plugging strength. It is suitable for plugging adjustment of fractured oil and water wells, heavy oil thermal recovery wells, thick strip water injection flow-through wells, and other low-permeability oil and water wells where plugging adjustment is not easy to inject.

Application
This series of products is made of readily available materials, environmentally friendly and pollution-free, widely applicable, with simple processes and convenient on-site construction. It has been widely used in the sealing of fractures in carbonate reservoirs, profile control of injection wells, sealing of high permeability water storage zones and steam channeling in thermal recovery wells, etc. More than 150 on-site construction results of various oil and water wells have been compared with similar products, and the success rate of plugging is much higher than other plugging products.
