摘要：Wax deposition of the gas-emulsion in intermittent flow with different water cuts and gas/emulsion superficial velocity in a flow-loop was investigated by crude oil, simulated oil, gas, and water as the experimental medium. In both the crude oil and simulated oil systems, the deposit was distributed around the pipe wall, and the deposit thickness decreased initially and then increased. These changes were induced by the increasing water cut resulting from the increasing viscosity and gelation point of the emulsions. The experimental results revealed that increasing gas and emulsion superficial velocity both have a negative effect on deposit formation.
