The Visual and Quantitative Study of the Microoccurrence of Irreducible Water at the Pore and Throat System in a Low-Permeability Sandstone Reservoir by Using Microcomputerized Tomography

<div>Different modes of irreducible water microoccurrence in the pore system: (a) conglobation pattern (ineffective oil reservoir space); (b) cluster pattern (partially effective oil reservoir space); (c) water-film pattern (effective oil reservoir space). Note: the yellow area represents a given pore or throat surface and the blue area represents irreducible water.</div>
