1.Surfactant-polymer flooding

DESHI GROUP is one of the earliest enterprises who is engaged in surfactant- polymer flooding research, in nearly a decade of research and practice in the process, DESHI GROUP has established a perfect data model of rock flooding in the bottom rock, has accumulated hundreds of surfactant products. In 2009, DESHI GROUP’s surfactant products were used in the polymer-surfactant flooding pilot project in high-temperature high-salt formation, which indicated that DESHI GROUP was in the forefront of the industry in the technology of surfactant for oil flooding.

2.Thermal chemical synthesis technology.

At present, DESHI GROUP has 16 subcritical wet steam generators, 1 supercritical wet steam generator, and has the perfect oil injection qualification. DESHI GROUP can carry out steam stimulation and steam flooding, can design perfect thermal chemical oil production solution according to the formation situation with the group's chemical technology superiority. Solutions Includes: high temperature anti-swelling technology, high temperature viscosity reduction and asphalt dispersion technology, high temperature foam and thermal profile control technology, surfactant flooding technology, CO2 preposition and N2 preposition technology. So far, they have come into use and have significant increase in oil production.

3.Tertiary oil recovery

Tertiary oil recovery technology is widely used in recent years, high water content in fluids in tertiary oil recovery, and have chemical substances such as high polyacrylamide content, high surfactants content. It is harder to separate oil and water, remove oil from sewage, sterilize. DESHI GROUP has overcome technology problems, and has solved a series of problems of high water content and high processing cost.

4.Oil and water treatment equipment and process.

DESHI GROUP is committed to environmental protection new technology, especially the development and utilization of new processes treatment of the tertiary oil recovery produced fluid, advanced and practical design concept for water treatment equipment and the company of tertiary recovery produced fluid processing technology bring out the best in each other. Main products and technologies are produced fluid of tertiary oil recovery dedicated filters and high efficiency degreasing agent, chlorine dioxide generator and residual chlorine removal device, series of drugs dosing device, three phase separator for oil-gas-water, and the maintenance and transformation of complete sets of technical equipment.
