Research On Hierarchical Production Allocation Of Pumping Wells High Water Governance Technology

The thesis is on the laboratory physical simulation experiment's research that is about enhanced oil recovery with high molecular weight polymer.We take the research on different viscoelastic jumping points caused by different concentrations' polymer solution.Meanwhile,affections of swept volume even viscosity ratio on enhanced oil recovery were deeply studied by us.The researching results of the thesis shows us three points:First,Increased values of viscoelasticity all show us peaks when unit concentrations of High Molecular Weight Polymer increased.Senond,all Parameters of characterized elastic increased when unit concentrations of High Molecular Weight Polymer increased.At last,recovery factor enhances after High Molecular Weight Polymer's injection,just for the reasons of increasing concentration of solution,higher System of viscoelasticity and reduction of crude oil and polymer solution's viscosity ratio.We could get full understanding of the mechanisation how polymer solution displaces crude oil after the research of the thesis.This thesis also makes great sense of how to have polymer flooding more effective and economic in practice,even in developing basic theory of polymer flooding.
