Product Introduction

Zijin can design, develop and supply chemical enhanced oil recovery (CEOR) technologies and products to significantly enhance waterflooding in oil fields. Zijin's chemical technology has been successfully applied to some oilfield projects around the world under challenging reservoir conditions. The application of each ton of polymer can produce an additional 50-120 tons of crude oil production.
At present, the formation temperature of Class II and III reservoir resources is 70-95 °C, the formation salinity is 10000-30000 mg/l, and the divalent ion is 800 mg/l. Under these conditions, the commonly used polyacrylamide will have serious thermal degradation, The increase in the degree of hydrolysis, the bonding and precipitation of high-valent ions and other problems, the viscosity-increasing effect becomes poor. The temperature-resistant and salt-resistant polyacrylamide produced by our company can meet the requirements of viscosity, temperature resistance, salt resistance, shear resistance and other requirements under the conditions of oil reservoirs, and has good oil displacement performance.
Services provided by Zijin can help evaluate target reservoirs and select good technologies.
Since 2000, Zijin Company has been committed to technology research and development as its most important resource. Zijin's technical team has more than 15 years of experience in polymer flooding and consistency control technology, and has a nationally certified laboratory for enhanced oil recovery experimental analysis.
Our R&D center, in cooperation with the Chinese Academy of Sciences, has successfully commercialized several major technologies including nanospheres and polymer flooding in offshore oilfields.
We have more than 16 employees working in the R&D department, and our annual R&D investment is no less than 4% of sales revenue, which is used for new product development, performance improvement and application technology innovation.
