Waterproof lock agent
This product is a new product developed for reduced productivity due to high shale content, loose oil layer structure, poor cementation performance, low permeability water sensitivity, water lock, large changes in crude oil properties, and operational pollution in the oilfield development . It can quickly and effectively solve the oil and water well pollution caused by factors such as water damage, develop the reservoir, increase the permeability, and increase the oil production capacity or restore the water injection efficiency.
