| 英文摘要 | Underground oil storage is the development trend for large-scale energy storage. The anhydrite rock cavern oil storage (ARCOS) has the potential to become an oil storage medium, and the tightness and stability are the key parameters to ensure the safety of oil storage. Thus, the novelty of this paper aims to analyze the tightness and stability of ARCOS from experimental and numerical research. In detail, a series of anhydrite rock experiments (permeability experiments, rock surface experiments, breakthrough experiments, water solubility experiments, component experiments and microstructure experiments) are conducted to evaluate the tightness of ARCOS based on Taian's anhydrite mine. A 3D numerical model is built to analyze the stability of ARCOS in two conditions (long-term and injection-production) by the three-dimensional explicit finite difference method. The results show that the permeability of anhydrite rock is low (10-20-10-19m2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{10}<^>{-20}-10}<^>{-19}{m}<^>{2}$$\end{document}), the anhydrite rock has high breakthrough pressure (9.61 MPa) which is less than maximum operating pressure (5.52 MPa), the solubility of anhydrite is only 0.011 g/100 g H2O. The maximum displacements of ARCOS under long-term and injection-production are 0.13 m and 0.18 m, respectively. The simulation results show great stability under the two working conditions. The research has a reference for the development of large-scale underground ARCOS. A novel underground oil storage method that uses anhydrite rock caverns is proposed.A series of anhydrite rock experiments are conducted to analyze the tightness of oil storage.A 3D numerical model is built to analyze the stability of anhydrite rock cavern.The application and prospects of anhydrite rock cavern oil storage are analyzed. |
