摘　　要：通过双河油田欠注井层原因剖析，射孔井段套管内壁堵塞是其主要原因之一。通常为了解除这种堵塞依靠酸化方法，但其投资大，有效期短。本文根据生产实践提出利用刮削冲洗方法解除这种堵塞。应用结果表明，该方法投资小，现场操作简单，解堵增注效果较好。Plugging on string inner wall in perforation interval is one of the main causes leading to insufficient water injection in Shuanghe oilfield. Acid treatment is used typically to remove these plugging, however, large amount of investment is needed and the validity period is short.A new scraping and washing method is proposed for use based on production practice in this paper. The amount of investment needed is small, field operation is simple and stimulation effect of injection well is good.
