| Abstract: | On the basis of laboratory experiment and field application on testing the oil displacement effect of wide molecule polymer,initially summarized are the characteristics of wide molecule polymer drive,mobilization feature of oil layer and the optimized method of wide molecule proportioning and evaluated is the flushing efficiency.Through tracing and adjusting the optimization and proportioning the wide molecule, the water cut is descended sharply and the oil production is arisen at the block.The recovery ratio in equal polymer amount,recovery degree and oil increase per ton of polymer are all high. |
