Abstract

Abstract:

In order to study available injection speeds in velocity sensitive experiment for low permeability cores,a capillary model is built based on pore throat radius and distribution,and the finite difference method is used to resolve the equations.The effects of particle release, surface deposition, and particle plugging of three different kinds of low permeability cores on permeability damage are simulated.The influences of different injection solutions for ultralow permeability cores on critical speed are also simulated. Simulation results show that particle release and particle deposition are the primary damage mechanisms for low permeability cores.The lower the permeability of cores, the more remarkable the permeability damage and the stronger the effects of the bridge plug and singlehole blockage on the permeability damage. For the core with permeability smaller than 1×10^-3 μm², the injection solution according to SYT5358-2010 is not reasonable and two points should be added under 0.1mL/min. The model results provide a theoretical foundation for injection solution in velocity sensitive experiment for low permeability cores.

Key words: capillary bundle model, velocity sensitive, critic flow rate, low permeability, injection flow rate
