安塞油田高含水油井化学堵水研究与现场应用

Study and field application of chemical water shutoff for high water cut well in ansai oilfield

针对安塞油田高含水油井,重点开展了压裂、增注等措施,取得了较好效果,但存在单井费用高、有效率低、效果差异大等缺点。对此,有针对性的采取了化学堵水技术,对恢复高含水油井的正常产能,提高油井采出程度,改善油藏整体开发水平起着至关重要的作用。

In view of the high water cut oil wells in Ansai Oilfield,measures such as fracturing and injection increase have been mainly carried out,and good results have been achieved.However,there are disadvantages such as high cost of single well,low efficiency and great difference in effect.Therefore,it is very important to adopt chemical water plugging technology to restore the normal production capacity of high water cut oil wells,improve the recovery degree of oil wells and improve the overall development level of oil reservoirs.
