摘　　要：随着东仁沟油田开发程度的推移,大量的油井在开发过程中由于各种原因导致了井筒和油层的堵塞、污染,致使油井不上液,产液、产油量下降,这篇论文针对东仁沟油田的储层条件和油井堵塞原因,对东仁沟油田长2油层化学解堵的42井次做了详细分析,对比了各种解堵技术在实际应用中的效果,为油田后期的化学解堵选井和技改挖潜提供了一定的依据。With the development of Dongrengou oilfield, a large number of oil wells formed the blockage and pollution of the wellbore and reservoir in the process of development because of various reasons, which resulte：l that the wells could not produce the liquid. In this paper, according to the reservoir conditions of Dongrengou oilfield and oil well plugging reasons, chemical deplugging conditions of Chang 2 reservoir were analyzed; practical application effect of various plug removal techniques was compared.
