Feasibility of the Same Viscosity Dilute Polymer Systems Prepared with Polymer-Bearing Wastewater
摘要
Abstract
The feasibility of preparation of the same viscosity dilute polymer systems with polymer-bearing wastewaterwas studied in the process of polymer flooding in Daqing oilfield.The concentration of oil displacement system,the system viscosity,shear resistance,viscoelasticity,stability and molecular thread size were measured on the basis of the inj ection capacity and oil displacement effect assessment.The results showed that under the same viscosity polymer performance, inj ection capacity and oil displacement effect were increased with the increase of concentration of system.Using wastewater containing polymer in Daqing oilfield to prepare diluted polymer solution had wide applicability.In view of the Senior Reservoir of Daqing oilfield,through calculating the experimental time reduction ratio,recovery factor improvement ratio,polymer dosage incremental,dilute polymer system (qw3 system)containing poly 430 mg/L was obtained with Longhu Lake water, which can realize comprehensive benefits.关键词
