Abstract:

In this paper,the tube-type inflow control device(ICD)is improved to overcome the constant Flow Resistance
Rating(FRR)which is both too large at low flow rate and too small at high flow rate,and this improvement is verified
by numerical simulation. To highlight the excellent performance of the self-regulation tube-type design,three other designs
(nozzle-based,helical channel,and tube-type)with a same FRR of 0.8 were compared to study fluid property sensitivities and
structural parameter optimization. The results show that the main fluid property sensitivity differences among the four designs
are flow rate,density,and viscosity respectively. And viscosity sensitivity is of the most. The structural parameters that affect
FRR are minimum flow area and flow path length. In addition,minimum flow area has a great influence on both erosion and
plugging resistance. To sum up,the self-regulation tube-type design has low viscosity sensitivity,large minimum flow area,
high erosion resistance,high plugging resistance,and its FRR will be adjusted automatically according to the reservoir flow
rate,thereby a more uniform inflow profile was maintained and total production was maximized.
