Abstract

A detailed literature review is conducted on the worldwide development and application of offshore chemical EOR technology in this paper. After about 20 years of research offshore chemical EOR techniques, a series of resolutions and techniques have been developed, including high-efficiency driving agents, platform polymer injection distribution technology, and produced fluid treatment technology. Since 2003, field tests and applications have been carried out in 3 oil fields in Bohai Bay, with expected oil increment and good economic benefit. On the other hand, Indonesia, Angola and Brazil have respectively succeeded in field pilot tests from single well to well group by means of polymer flooding in high water-cut stage in hightemperature and high-salt offshore oilfield, early-stage polymer injection in deep-water oilfield, and offshore polymer injection with horizontal injectors. All of these have enriched the field application experience in offshore chemical flooding, which is a new road for increasing recovery rate of offshore oil field and provides a solid technical guarantee for the economic and efficient development of offshore oil fields.
