Phenolic Resin Based Supramolecular Aggregates-Novel In-Depth Profile Modifier for Oil Reservoir

Abstract:

The aggregates size, plugging and propagation properties for supramolecular aggregates based on phenol-formaldehyde resin have been investigated by measurement of hydrodynamic diameter, filtration with nuclear pore film and plugging test with sand-pack core. The results show at the condition tested, supramolecular aggreates have an average hydrodynamic diameter of about 450 nm, and can sufficiently plug 1.2 μm-nuclear pore film. The aggregates can plug, propagate, replug and repropagate in porous media, which is an obligatory property of an in-depth profile modifier for oil reservoir.
