摘　　要：修井液的漏失、浸泡造成的黏土矿物膨胀伤害导致储层污染,需要进行酸化解堵作业解除近井地带的污染以提高产能,结合针对此类问题的处理经验,经过详细的分析和试验,作业井采用有机解堵剂+多氢酸体系,作业后有效地提高作业井的采液指数,增产效果显著。The loss of workover fluid and swelling damage of clay minerals caused by immersion can lead to reservoir pollution.To improve the production capacity,it is necessary to carry out acidizing and plugging removal operation to remove pollution near the well.Combined with the treatment expe-rience of such problems,through detailed analysis and tests,the well adopts“organic plugging re-moval agent+polyhydric acid system”,which effectively improves the fluid production index of the well after operation,and has a significant increase in production.
