Abstract: Micro-jel flooding is the main trend to lower polymerflooding cost and improve ploymerflooding effect at present, but there lacks mature field injection allocation technology. This paper studies crosslinker feeding position, crosslinker pump and its flow rate control, pipeline selec- tion according to the properties of the selected crosslinkers. Based on these study results, the present polymerflooding injection allocation technology is improved and an optimum micro-jel flooding field injection allocation technology is developed. The three pilots of micro-jel flooding carried out during 1998-1999 show that it is simple, easy to operate and highly applicable with a well head jollification rate above 80%.
