On Petrophysical Experiments for Polymer Flooded Reservoir in Extra High Water Cut Stage of Daqing Placanticline
摘要
Abstract
After many years' developments, La,Sa &- Xin oilfields in Daqing placanticline have entered into extra high water cut stage. Polymer flooding has been widely applied in the fields. Along with polymer agent injection, physical properties and fluids distribution of reservoirs have changed. To recognize the changes of logging curves in polymer flooding reservoirs, the indoor reservoir petrophysical experiments have been made to systemically analyze the polymer solution characteristics of conductivity and the sound propagation. Electricity, acoustics, nuclear magnetic resonance parameters of the core samples are measured with the water and polymer flooding core samples tests. Results suggest that the polymer flooded cores are similar to the water flooded cores with the same salinity in the changes of electrical properties, and the diffusion-adsorption e-lectric potential trends to decrease, so it is difficult to use nuclear magnetic resonance T2 spectrum to identify the polymer flooding effectiveness. This study lays a foundation for establishing identifying standard of flooding degree and calculating parameters in polymer flooding reservoirs.关键词
