摘　　要：为进一步挖掘苏里格气田中部苏A区块低产低效井增产潜力,开展了低产低效原因分析和增产潜力评估研究,优选井筒及近井地带积液和结垢而导致的低产低效井为挖潜增产的主要对象。通过研究和现场实践,确定了优选措施井层的“5+5”标准,开发了解堵挖潜工作液体系,现场试验6口井,平均日增产(2.3~3.8)×10^(4)m^(3),增产效果显著。In order to further tap the stimulation potential of low production and low efficiency wells in Su A block in the middle of Sulige gasfield,the cause analysis of low production and low efficiency and the evaluation of stimulation potential are carried out,and the low production and low efficiency wells caused by fluid accumulation and scaling in the wellbore and near the well are selected as the main objects of potential stimulation.Through research and field practice,the"5+5"standard for the optimal measure well layer is determined,the plugging and tapping potential working fluid system is developed,and 6 wells are tested in the field.The average daily production increase is(2.3~3.8)×10^(4)m^(3),and the production increase effect is remarkable.
