Аннотация

Steam assisted gravity drainage (SAGD) is an oil recovery technology where the mixture of bitumen and sand flow into a production well through slots (Dh ~ 1 mm) drilled on a pipe located in the well. Study of the flow passing through these slots is critical to identify and develop understanding of failing mechanisms in SAGD processes such as plugging, scaling, and fouling of the slots. In SAGD process, where the electrolytic fluids are present in the flow of bitumen into the production well, it is expected that the electro-kinetic phenomena play an important role in the failure mechanisms of slots. The aim of this study is to experimentally identify the effect of electro-kinetic properties of particles on the fouling in a laminar flow through mini channels. A flow cell is made from PMMA acrylic sheets for the experiments. Two electrodes are attached to channel walls to apply the electric field that is generated using an external power supply. Particle image velocimetry (PIV) is used to study the velocity field and the deposition of particles on the channel walls. To remove the electro-osmotic effects in the flow, distilled water is used as a carrier liquid. The results from this study is expected to describe the migration of particles in laminar flow through mini-channels and its contribution in fouling mechanism in SAGD wells
