Abstract: This research aims to investigate the mobilisation and flow of multi-oil slugs in a capillary model saturated with water, for simulating the motion of oil droplets trapped inside the porous medium of an oil reservoir. The mobilisation and stabilisation points of multi-oil slugs in the model are quantified under various experimental conditions with different numbers of oil slugs. The maximum pressure required to mobilise the oil slugs is identified. For generating a stabilised flow, the oil slugs are all found experiencing consecutively the following pressure and movement change patterns: motionless - slowly increased pressure drop - dramatically increased pressure drop - flow impending - flow stabilised. An analysis comparing the pressure drop and oil slugs travelling displacements for one, two, and three oil slugs are carried out. The research contributes to a better comprehension of the mechanism of mobilisation and the flow of multi-oil slugs subjected to capillary force and externally applied pressure.
