Determining Residual Resistance Factor of Weak Gel Through Physical and Numerical Simulation

摘要

The residual resistance factor of weak gel plays an important role in predicting gel flooding performance. Physical and numerical simulation was employed to determine this parameter for Faulted Block 6 in Region 1 of Gangdong Oilfield. Sandpack models with various permeability properties were built to simulate different formations. Different values of the factor were determined through physical simulation of weak gel flooding with the models. Numerical simulation was conducted subsequently to match the history performance of the physical simulations through modifying the primary values of the residual resistance factor. Finally a relationship between this factor and the formation permeability was established.
