A Study On Enhanced Oil Recovery After Polymer Flooding In Xing Bei Exploitation District

Although polymer flooding had being a effective means to enhanced oil recovery, this technology must be consummated. The reasons as follows:there is lots of remainder crude oil after polymer flooding in the reservoir, the water cut rises quickly after polymer flooding changed water flooding and plentiful remainder polymer in the reservoir will be wasted.The flocculated technology makes use of the polymer again and products flocculated things to jam big passageway in the reservoir. This article puts forward that using flocculated technology will realize enhanced oil recovery in Xing bei exploitation district. In this paper, we studied flocculated agent choice, flocculated agent prescription, flocculated agent mechanism and enhanced oil recovery capacity.
