地下水封油库在建设及运营过程中洞室涌水量大小是影响洞库水封安全和运营成本的重要因素.目前地下水封油库工程建设中采用传统的注浆方式难以将围岩渗透性降低到设计要求,因此洞室涌水量得不到很好的控制.微生物诱导碳酸钙沉淀(MICP)技术具有注浆黏度低、环境适应性强、生成矿化物质稳定等显著优点,引起了学术界与工程界广泛的兴趣和研究.本文首先分析了地下水封油库涌水量控制中存在的相关问题,然后阐述了 MICP技术对裂隙渗流控制的机理、影响因素以及对裂隙渗透性的影响效果,最后探讨了 MICP技术在地下水封油库中应用的关键问题.通过分析表明,MICP作为地下水封油库渗流控制的一种辅助注浆方式,可以较为准确地控制围岩渗透性变化,达到对洞室涌水量有效控制的目的.
APPLICATION POTENTIAL OF MICP IN SEEPAGE CONTROL GROUT-ING OF UNDERGROUND WATER-SEALED OIL STORAGE CAVERN
In the process of construction and operation of underground water-sealed oil storage cavern,the water inflow of the caverns is an important factor affecting the safety and operation cost of the cavern.At present,it is dif-ficult to reduce the permeability of surrounding rock to the design requirements by using the traditional grouting method of underground water-sealed oil storage cavern,so the water inflow of the caverns cannot be well controlled.Microbial-induced calcium carbonate precipitation(MICP)technology has the advantages of low grouting viscosity,strong environmental adaptability,and stable formation of mineralized substances,which has attracted extensive in-terest and research in academia and engineering.This paper first analyses the problems existing in water inflow con-trol of underground water-sealed oil storage cavern.Then,the mechanism,influencing factors and the effect of MICP technology on fracture seepage control are expounded.Finally,the key issues of the application of MICP in underground water-sealed oil storage are discussed.The analysis shows that MICP,as an assisted grouting method for seepage control of underground water-sealed oil storage,can accurately control the change of surrounding rock permeability and achieve the purpose of effective control the water inflow.
