Application of Non-oxidative Depolymerization Technology in Bohai X Oilfield
Due to the long-term impact of polymer injection,aged polymer blockages are common in oil and water wells in Bohai oilfields,which seriously affects the normal production of the oilfield.Using experimental screening and evaluation methods,a non-oxidative depolymerization system was selected and successfully applied on site.After the application,the apparent water absorption index of the well increased by 2.99 times,indicating that the chemical system can effectively remove the aged polymer composite scale and can be further promoted and applied.
