Title: Effect of the Physical Simulation Flooding in the Laboratory in Different Injection Time
Abstract: Nowadays,the output of polymer flooding in Daqing oilfield has surpassed 100 million tons,and it has created tremendous economic benefits.To ascertain the rational time in polymer injection become a problem concerned by all of the science and technology personnel,thus,the enhancing recovery percent function of polymer flooding will be fully exerted.According to the requirement of oilfield development,we started to process physical simulation experiments in the laboratory on man-made 1-D rectangle core and 2-D plane core,on condition that the water cut is different.The result shows that if we inject the same polymer solution in weight,the flooding effect will be better when the water cut is 75% than when it is 95%,whatever the experiments were on the rectangle core or the place homogeneous core.
