摘要:

针对喷管型流入控制装置(ICD)在低流量下流动阻力等级(FRR)过大,而高流量下过小的不足,提出了改进
思路,并进行了数值验证。为了更好地评价装置改进后的性能,选取流动阻力等级为0.8 的其他3 种ICD(喷嘴型、喷
管型和螺旋通道型)与之比较,并通过数值模拟手段对各装置的流体参数敏感性及结构参数优化进行研究。研究结果
表明:不同装置受不同流体敏感性的差异主要体现在黏度上。FRR 大小取决于最小过流面积大小和流道长度,而最小
过流面积影响ICD 的抗冲蚀和防堵塞性能。自调流式喷管型ICD 对黏度变化较不敏感,最小过流面积较大,抗冲蚀
和防堵塞性能较强,并能够根据储层流量的大小自动调整FRR,使得流入剖面更加均匀,总产量最大。

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.
