地下石洞油库防渗注浆圈特征参数对水封性能影响研究
Research on influence of characteristic parameters of impermeable grouting ring on water-sealing performance of underground rock cavern oil storage
摘要
Abstract
Underground water-sealed rock caverns serve as a primary method for petroleum storage,where grouting is essential for ensuring water-sealing performance.This study investigates how the permeability coefficient and thickness of the impermeable grouting ring influence containment efficiency.Based on a Chinese underground oil storage project,a two-dimensional oil-gas two-phase flow model is developed using finite element simulation.Results demonstrate that the grouting ring effectively controls both hydrocarbon diffusion and water inflow.Hydrocarbon diffusion increases with permeability and decreases with ring thickness,expanding over time following a power function.Water inflow reduces significantly after grouting,it distributes as crown>sidewall>invert,and decreases further with greater ring thickness.The optimal parameters are identified as a permeability coefficient of 8.64×10⁻⁵ m/d and a thickness of 14 m,achieving both effective sealing and economic benefits.These findings provide practical guidance for designing similar water-sealed storage facilities.关键词
