High concentration polymer flooding, resistance coefficient, residual resistance coefficient, molecular coil dimension, compound polymerAbstract
According to the practical demand of oilfield, instrumental analysis, physical simulation and reservoir engineering theory are applied for the experimental study on the influence of polymer concentration on the seepage characteristic of polymer solution, molecular coil dimension Dh and its distribution, oil displacement effect, besides, an analysis is made on the enhanced oil recovery mechanism by compound polymer flooding with broad relative molecular mass distribution. It turns out that for polymer with the same concentration, the resistance coefficient FR and residual resistance coefficient FRR decrease as core permeability increases; for the same core permeability, FR and FRR increase as polymer concentration increases. For polymer with broad relative molecular mass distribution compounded by 3 polymers (middle molecule, high molecule and ultrahigh molecule), with larger proportion of ultrahigh- molecule polymer, the molecular coil dimension Dh in compound polymer increases. The physical simulation indicates that while the polymer solution viscosity is identical, the flooding effect of compound polymer is better than that of high molecular polymer, and with increase of proportion of ultra-high-molecule polymer in compound polymer, the growth of recovery efficiency also increases.
