Study On Matoning Polymer With Reservoir And Injection Way

Polymer flooding technology in Daqing oil field has developed quickly. In1972,polymerflooding began to carry on field test, and then carried on small well spacing test, Saertu thickreservoir test and pilot test in Zhongquxibu. After the success of the pilot test in Zhongquxibu,industrial test was carried on in Daqing oil field,and has made good test results. Especially ithas through the research of the key scientific and technological. Then a series of supportingtechnology in polymer flooding field has been developed. Since that time polymer floodingtechnology has entry into industrial phase.Calculated oil recovery, resistance coefficient and residual resistance factor based on theexperimental. And then we did the study on the adaptability of molecular weight with the coreand the adaptability of polymer solution concentration with core.The practice has neither consideration of the changes of sedimentary characteristics norsubdividing interpretation unit, so the interpretation accuracy is hard to meet the demand ofproduction, which can have a major impact on making perforation scheme for new drillingwell of productivity construction blocks and fine adjustment and digging the potential ofGaotaizi zones of the oilfield. In recent years, with the coring data being constantly enriched,our geological understanding is being gradually deepened, we already have the researchconditions for parameters interpretation method of Gaotaizi zones in Sazhongdevelopment district.This work got good purposes in the practical experiments, and has played an importantpart in polymer flooding of oil production. The injection way could improve the polymerflooding effects and enhance the economic effection. The study on matching polymer withreservoir and injection way is very perspective in the polymer flooding oil field.
