The Research Of Polymer's Log Response

With oil displacement technique of polymer extensively using and spreading, extensively using and spreading,at the momen,a lot of blocks have entering follow-up displacement of oil by water period,many foreign big oil company have researched polymer's character,but they have researched polymer's log response mechanism a little,in the past few years,the oil displacement technique of polymer has extensively been used and spreadedin our country,and oil displacement technique of polymer is the best in the world.They else researched polymer's injection proration mechanism and character.Different injection proration method is defferent of log response mechanism.When reservoir polymer was submerged by water,physical property of reservoir has been changed,and electric property has been changed too.for example, GuanTao group of the first zone of GuDao oil field was maked up by fresh water and was sewaged,and the eighth zone of GuDong was maked up by fresh water and was sewaged,this time we begined with the datum of geology,well logging,history.theory was guided by developed geologyand developed well logging.Researched the well logging's macro rule of deferent developing period by experimenting and analyzing couplet well.Revealed microscope rule of the well logging feature.Accurately established the well logging's interpretation model by dynamics datas.This kind of method enhanced interpretation accuracy degree.
