摘　　要：在调查大庆外围榆树林油田注水井井筒结垢情况的基础上,采用新的方法分析了地层的结垢类型和结垢量,并通过岩心模拟实验,分析了垢对地层的伤害程度,确定出垢在地层中的分布规律,进而研究了水井中各堵塞因素及堵塞半径,为确定酸化解堵规模提供了依据。Based on the preliminary scale analysis for the water injection well in Yushulin Oilfield,the advanced methods were applied to analyze the scale type and volume.Then the rule of scale distribution was determined by core simulation test.Moreover,plugging factors and plugging radius were studied,which provided proof for determining plug removal scale.

关 键 词：结垢 结垢规律 堵塞原因 解堵半径
