薄油缘油田的石油生产可能具有挑战性，因为这些油田容易出现气体锥进。这些气田的天然气产量过多导致产量和采收率不佳。因此，这些资源需要先进的采收方法来提高石油采收率。

当今广泛使用的回收方法之一是先进的流入控制技术，例如自主流入控制阀（AICV）。 AICV 限制了发生突破的区域的天然气流入，从而可能提高薄油环油田的采收率。

本文根据实验和模拟的结果，对 AICV、被动流入控制装置 (ICD) 和砂筛进行了性能分析。在典型的 Troll 油田油藏条件 (RC) 下，使用轻油、天然气和水进行单相流和多相流实验。

从实验中获得的数据是设备两端的压差与不同相的体积流量。实验结果证实 AICV 限制气体产生的能力显着增强，尤其是在气体体积分数 (GVF) 较高的情况下。对考虑防砂管、AICV 和 ICD 完井的薄油环油田的近井石油生产进行了建模。在本研究中，仿真模型是使用 CMG 模拟器/STARS 模块开发的。

采用 AICV 完井，与 ICD 和砂筛相比，累计产气量分别减少 22.5% 和 26.7%。结果还表明，与使用 ICD 和砂筛管相比，AICV 累计产油量提高了 48.7%。

模拟结果证实，与使用 ICD 和砂筛管的情况相比，使用 AICV 完井的井在更长的时间内以有利的气/油比 (GOR) 生产。这项工作的新颖之处在于新型 AICV 的多阶段实验以及模拟器中数据的实现。

提出了 AICV/ICD 仿真的工作流程。基于所提出的工作流程的模拟结果与 AICV 实验性能结果一致。正如这项工作所证明的那样，在最具挑战性的高气油比轻质油藏中部署 AICV 对于提高产量和采收率是有益的。

Oil production from thin-oil-rim fields can be challenging as such fields are prone to gas coning. Excessive gas production from these fields results in poor production and recovery. Hence, these resources require advanced recovery methods to improve the oil recovery.

One of the recovery methods that is widely used today is advanced inflow control technology such as autonomous inflow control valve (AICV). AICV restricts the inflow of gas in the zones where breakthrough occurs and may consequently improve the recovery from thin-oil-rim fields.

This paper presents a performance analysis of AICVs, passive inflow control devices (ICDs), and sand screens based on the results from experiments and simulations. Single- and multiphase-flow experiments are performed with light oil, gas, and water at typical Troll field reservoir conditions (RCs).

The obtained data from the experiments are the differential pressure across the device vs. the volume flow rate for the different phases. The results from the experiments confirm the significantly better ability of the AICV to restrict the production of gas, especially at higher gas volume fractions (GVFs). Near-well oil production from a thin-oil-rim field considering sand screens, AICV, and ICD completion is modeled. In this study, the simulation model is developed using the CMG simulator/STARS module.

Completion of the well with AICVs, reduces the cumulative gas production by 22.5% and 26.7% compared with ICDs and sand screens, respectively. The results also show that AICVs increase the cumulative oil production by 48.7% compared with using ICDs and sand screens.

The simulation results confirm that the well completed with AICVs produces at a beneficial gas/oil ratio (GOR) for a longer time compared with the cases with ICDs and sand screens. The novelty of this work is the multiphase experiments of a new AICV and the implementation of the data in the simulator.

A workflow for the simulation of AICV/ICD is proposed. The simulated results, which are based on the proposed workflow, agree with the experimental AICV performance results. As it is demonstrated in this work, deploying AICV in the most challenging light oil reservoirs with high GOR can be beneficial with respect to increased production and recovery.
