Latest Patents
Zhang's latest patents include an injection stimulation agent for water injection wells and a preparation method and application thereof. This innovative agent comprises a raw material composition that includes 5.0%-10.0% of sulfamic acid, 10.0%-20.0% of methanol, 10.0%-20.0% of tartaric acid, 10.0%-20.0% of ethylenediamine tetramethylene phosphoric acid, 5.0%-10.0% of sodium polyacrylate, 5.0%-8.0% of cocoyl hydroxyethyl sulfonic acid, and the balance of water. The agent is designed to be used in the acidizing treatment process of reservoirs, effectively shrinking swelled clay while dissolving scale to achieve depressurization and enhanced production.
Another significant patent is for on-line diverting acids for continuous injection into water injection wells. This patent details a raw material composition that includes 5.0%-25.0% of hydrochloric acid, 3.0%-6.0% of ammonium fluoride, 4.0%-8.0% of a diverting agent, 3.0%-7.0% of a chelating agent, 1.0%-3.0% of a corrosion inhibitor, 1.0%-3.0% of an anti-swelling/swelled-clay-shrinking agent, and a balance of water. These on-line diverting acids are capable of removing plugging from deep zones of high and low permeability layers, simplifying the construction process while reducing pressure and stimulating injection.
