低产低效探井复查与增产工艺

Review and stimulation for lowproductivity & lowefficiency exploratory wells

通过近几年来开展的低产低效探井复查工作 ,分析了部分井的低产原因 ,阐述了增产工艺。对筛选出的 2 2口低产低效探井实施了增产工艺 ,见效井 15口 ,成功率 6 8% ,平均单井日增油 9.5t。所采取的增产工艺技术能充分挖掘低产低效探井潜力。

The reasons of low productivity of some old wells are analyzed, and the stimulation is given by the review of the old wells in recent years. The stimulation treatments have been implemented in selected 22 wells with the result of 15 response producer, 68% of success ratio and 9.5t of average daily incremental oil production for single well. The applying stimulation technique can tap the potential of old wells sufficiently.
