复配聚合物驱油效果及影响因素研究
摘要
Abstract
A reservoir in Daqing Oilfield has characteristics of low permeability, strong intralayer and interlayer heterogeneity, well - developed fractures and high capacity channels, leading to channeling of injected water and poor water flooding result. For the need of reservoir development, laboratory instrument and physical simulation are employed to evaluate the molecular coil dimension and viscosity property of compound polymer solution and compare with "super - high" polymer solution. On this basis, the injecting parameters of polymer solution water have been optimized through experimental study. The results indicate that compared with "super high" polymer, the compound polymer has a wider range of molecular coil dimensions (expressed as Dh) , lower loss factor, better viscosity - enhancing property, and can remarkably improve recovery factor. With the decreasing of salinity, the viscosity of compound polymer solution increases, so does recovery factor.关键词
