Regarding the issue of high water injection pressure and inability to meet the designated injection volume in a certain block of the X oilfield,the reasons for under-injection were analyzed based on factors such as reservoir characteristics,formation oil-water properties,and water quality of injections.Based on this analysis,a management approach was adopted that encompassed measures such as relieving blockages,preventing clay expansion,stabilizing and consolidating sand,and reducing pressure to enhance capacity.To achieve this,techniques for sand consolidation and blockage removal were applied in loose sandstone,thus presenting a new avenue for balancing the injection-production relationship.
