摘要
Abstract
Chunguang Oilfield have entered into the development stage of high water content,high recovery and production decline.In view of the current problems such as the reduction of new reserves,the dispersion of remaining oil,and the difficulty of tapping potential,the oilfield urgently needs to a new development mode so as to further tap the potential of the remaining oil and achieve stable production of the oilfield.The experiment of"enhanced foam+gel"flooding was carried out,and the results of different media displacement showed that the enhanced oil recovery effect of the 0.4％P2-1+0.1％warm rubber reinforced foam system was much better than that of the single media system.The results of multi-round injection experiments with different media show that when the amount of slug is the same,the more injection rounds and the more slug plugs,the higher the enhanced oil recovery,and the increase of slug can increase the coverage and permeability area of the slug system to the reservoir,thereby improving the driving effect of crude oil and increasing the oil recovery.关键词
