专利号:US-2012267111-A1 优先权日:2009-12-30 标题 :Synthesis of Degradable Polymers Downhole for Oilfield Applications 发明人:KHLESTKIN VADIM KAMIL EVICH 权利人:KHLESTKIN VADIM KAMIL EVICH 摘要:A method is given for polymerizing monomers downhole to create well treatment polymers. The monomers each contain two polymerizable groups and a degradable group or groups which allow the polymer to degrade under downhole conditions, for example by hydrolysis. Polymerization downhole allows easier, more precise, placement of polymer. Polymer obtained from monomers pumped downhole may be used, for example, for fluid diversion plugs, isolation plugs, formation consolidation, flowback control, and fluid loss control. Synthesized polymer may form gels, films, solids or other structure in treated wellbores, fractures, and/or formations. After the desired effect is achieved, the deposited polymer degrades and the polymer degradation products dissolve, leaving the wellbore, fracture and/or formation clean, with no damage that might have decreased fluid flow.
