Injection technology improvement and development direction of Hu Jianshan oilfield

The stratified water is one of the main contents of the project to improve the recovery rate, to further improve the primary well pattern water flooding recovery, since 2010, Hu Jianshan oilfield continue to promote the fine layering water injection, separate water injection rate has increased substantially, with remarkable results. The process from 2009 to carry out the eccentric separate injection, 2011 promotion bridge eccentric separate injection, to2013 promotion bridge concentric filling, continuously expand the injection technology application in highly deviated wells, produced water reinjection wells, multilayer segmentation well, improve the injection well testing efficiency and accuracy, and gradually form the supporting technology of separate layer water injection technology of low permeability oilfield.
