| 英文摘要 | The open hole of wellbore may pass through one or several mudstone interlayers during the construction of the salt cavern gas storage in thin interbedded salt mines. Once an interlayer is formed, leakage occurs that will cause the sealing failure of the wellbore. Based on the treatment project executed to ameliorate the wellbore sealing failure in Jintan's (China) salt cavern gas storage, a feasible grouting scheme and plugging evaluation criteria are proposed for similar, leaking interlayers. Combined with geological conditions and leaking types used to establish a radial grouting model, theoretical and numerical solutions for the plugging range are implemented. According to the grouting and plugging parameters used for analyses, the engineering practice indicates that the squeeze ultra-fine grouting can successfully plug this leaking interlayer and the depleted wellbore meets the requirements of storing natural gas that can be used for secondary utilization. The sealing effect mainly depends on the plugging range, which is affected by the grouting parameters, physicochemical properties of grout, and by the fluid-solid coupling. The results show that the viscosity rheology can inhibit grout diffusion, while the grout-rock coupling can promote grout diffusion. Their effects are completely opposite. Finally, the established plugging evaluation criteria can be used to analyze the plugging effect in the short and long-terms, and will have a good theoretical and practical guiding significance for the formation of sealing and gas leakage analysis of underground gas storage (UGS) in the future. |
