Research and application of water flooding injection and production technology after polymer flooding

For reservoir water flooding after polymer injection points existing in the mining process of high temperature resistant performance is poor and multistage unlock difficulty, examination, sealing problems such as in-depth study analysis, innovation to a new set return spit production technology, produce more suitable voltage can be found on variety well conditions column helpful for better improvement tube service life, At same time, it effectively solve problem clogging downhole concentric test adjustment unit. Oilfield exploration into follow-up stage, will show fast, fast decline, characteristics so often need take back but technology has pressure resistance difficulty problem, makes life shorter, according technical The effective outcome measures are put forward provide necessary support benefit flooding.
