The enhanced oil recovery (EOR) technology mainly addresses the issues that arise during oilfield development: First, waterflood development enters the high or ultra-high water cut production phase, leading to problems such as water flooding, water breakthrough, formation sensitivity, and blockage; second, thermal recovery, such as steam injection and hot water injection (for heavy oil), leading to steam breakthrough or uneven steam absorption, for which solutions are proposed. Our company primarily engages in the research and service of oilfield enhanced oil recovery technology. We have established eight major technical systems centered around the application of polymer gel deep-profile control technology: water blocking, profile modification, drive adjustment, polymer gel flooding, functional polymer flooding, SP composite flooding, ASP composite flooding, and associated tracer technology research and application.

The implemented technical measures include three major disciplines and ten aspects: reservoir engineering (remaining oil distribution research technology, identification of water flow preferential channels, scheme optimization and effect prediction, measures effect evaluation technology), chemical engineering (reservoir and formulation adaptability research technology, oil well produced fluid detection technology), and oil recovery engineering (water treatment for injection fluid, dynamic tracking and adjustment technology, injection equipment manufacturing technology).
