摘要: 基于垦东油藏真实地质结构,建立了含水层和盖层几何模型,并利用COMSOL仿真平台的多孔介质两相流、达西定律及固体传热接口,构建了大尺度油藏含水层压缩空气储能系统(CAESA)地下部分的物理模型,从而实现了从建库到循环注采全阶段动态仿真。在基准工况下,模拟了全阶段储层内气相饱和度、温度场和压力场的演化过程;并对注采稳定阶段进行敏感性分析,探讨了渗透率、注采速率、水平井长度及位置对井筒平均温度与压力的影响规律。结果表明:高渗透率、低注采速率和较长的水平井长度,会降低循环注采时井筒与储层间的温度差和压力差,水平井位置的影响取决于其与盖层的平均距离,距离增大会导致温度差增大而压力差减小。对比发现,渗透率和注采速率对压力的影响更为显著,渗透率从600 mD增至1 400 mD,注气速率从12 kg/s增至20 kg/s时,峰谷压力差分别减少约28.9%和24.1%,显著超过同等变化幅度下水平井长度和位置的影响。本研究可为油藏CAESA系统设计及能效评估提供理论指导。

Abstract: According to the actual geological structure of the Kendong oil reservoir, a geometric model of the reservoir aquifer and caprock was established. Using the COMSOL simulation platform, a large-scale subsurface physical model of the compressed air energy storage in aquifers (CAESA) system in oil reservoirs was constructed by integrating interfaces such as porous media two-phase flow, Darcy’s law, and solid heat transfer to enable dynamic simulation of the full cycle from gas injection for reservoir construction to cyclic injection production. Under baseline conditions, the temporal variations of gas saturation, temperature field, and pressure field within the reservoir during the full cycle were simulated. A sensitivity analysis was conducted for the steady injection-production stage to investigate the impacts of permeability, injection-production rate, horizontal well length, and well location on the average wellbore temperature and pressure. The results reveal that increased permeability, reduced injection-production rates, and extended horizontal wells decrease the thermal and pressure differences between the wellbore and reservoir during cyclic injection production. The impact of horizontal well location depends on its average distance from the caprock: a greater distance results in a larger temperature difference but a smaller pressure difference during injection production. Comparative analysis reveals that permeability and the injection-production rate have more substantial impacts on wellbore pressure. In particular, when permeability increased from 600 to 1 400 mD and the injection rate from 12 to 20 kg/s, the pressure amplitude decreased by approximately 28.9% and 24.1%, respectively, substantially exceeding those of equivalent variations in horizontal well length and location. This study provides theoretical guidance for the design and energy efficiency evaluation of the CAESA systems in oil reservoirs, specifically regarding well configuration and operational parameter optimization.
