摘要

为探究CO₂封存地层压力演化规律,避免封存场所内完钻井筒发生CO₂泄露,基于多孔介质多相渗流理论,建立了CO₂储层-盖层数值模型,厘清了封存过程地层压差的演化特点,分析了关键工程地质因素的影响规律。研究表明:注入CO₂引起储层及盖层压力上升,停注后,地层压力逐渐耗散,压力变化范围远超CO₂扩散半径;盖层压力响应具有滞后性,导致层间压差动态演化,且在注入初期存在压差峰值,易造成井筒泄露;压差峰值与距注入井距离、储层温度压力、储层孔渗性、储层厚度成负相关指数关系,与注入速度成正相关线性关系;对于规模CO₂地质封存,应控制CO₂注入井与完钻井的距离,选择埋藏深、厚度大、高孔高渗层位作为CO₂注入点有助于减小井筒泄露风险。研究成果可为CO₂地质封存提供参考。

Abstract

To investigate the evolution of reservoir pressure during CO₂ storage and to prevent wellbore leakage during the well drilling and completion within the storage site, this study established a numerical model of the CO₂ reservoir-caprock system based on the theory of multiphase flow through porous media to clarify the characteristics of the pressure difference evolution during the storage process and to analyze the influence patterns of key engineering geological factors.The study shows that: the injection of CO₂ leads to an increase in pressure within both the reservoir and caprock.After injection ceases,the reservoir pressure gradually dissipates,with the pressure change range significantly exceeding the radius of CO₂ diffusion.The caprock pressure response is delayed,causing dynamic evolution of interbed pressure differences,and there is a peak in pressure difference during the early stages of injection,which can easily lead to wellbore leakage.The peak pressure difference is negatively correlated with the distance from the injection well,reservoir temperature and pressure, reservoir pore permeability,and reservoir thickness,and positively correlated with the injection rate in a linear relationship.For large-scale CO₂ geological storage,controlling the distance between CO₂ injection wells and completion wells,and selecting injection points in deep-buried,thick,high-permeability,and high-porosity beds can help reduce the risk of wellbore leakage.The results of this study can provide a reference for CO₂ geological storage.

Key words： CO₂ storage; formation pressure; wellbore integrity; numerical simulation; multiphase flow
