摘　　要：针对X油田某区块注水压力高、注水量达不到配注的问题,文章从油藏特征、地层油水性质、注水水质等因素出发,分析欠注原因。在此基础上,采取“解除堵塞、黏土防膨、稳砂固砂、降压增能”治理思路,开展疏松砂岩稳砂解堵工艺技术应用,为平衡注采关系提供了新的途径。Regarding the issue of high water injection pressure and inability to meet the designated injection volume in a certain block of the X oilf ield,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.
