阐述了朝阳沟油田注水井微观出油机理和宏观出油机理,以及逆向驱油(注水井转抽)可以克服毛管力的圈闭作用和贾敏效应,证明了在毛管力作用下注水井周围的油层中存在大量的剩余油,为挖掘低渗透油田剩余油潜力提供理论依据.结果表明:注水井转抽后,对固体堵塞具有一定的解堵作用,增加水驱油面积;还可以较大地克服毛管力的圈闭作用. The microscopic oil-out mechanism and macroscopic oil-out mechanism of water injection well in Chaoyanggou oilfield and the trap effect and Jia-Min effect of capillary force can be overcome by reverse oil displacement (injection well pumping). It is proved that the micro- So as to provide a theoretical basis for excavating the potential of remaining oil in low permeability oilfield.The results show that after the injection well is turned to pump, it has a certain effect of plugging on the solid blockage and increases the water flooding area; Overcome the trap of capillary force.
