摘要
对氮气泡沫复合体系进行了相应的性能评价。结合氮气泡沫复合体系的特点,针对底水油藏水平井堵水过程中存在的难点,提出了远调近堵、压锥和堵水相结合的工艺。利用三相泡沫中的微球,在底水油藏深部实现反向调剖作用,并在曹妃甸11-1油田A67H井中,实现了现场应用,取得了良好的堵水效果。
In this paper,the performance evaluation of the nitrogen foam composite system is carried out.Combined with the characteristics of the nitrogen foam composite system,aiming at the difficulties existing in the horizontal well water plugging process in the bottom water reservoir,a technology combining remote plugging,pressing cone and water plugging is put forward.It has been successfully applied in well A67H of Caofeidian 11-1 oilfield and achieved good water shutoff effect.
