地下水封石油洞库渗流场-应力场耦合作用研究综述

Review of research on seepage-stress field interactive effects on groundwater-seal petroleum storage caverns

石油和天然气储备已经被许多国家提到了战略的高度上,地下水封石油洞库作为原油储备的方式之一在中国已经进入实施阶段。本文通过综述国内外地下水封石油洞库渗流场-应力场耦合作用机理研究的现状、研究实际工程中遇到的问题、主要的研究手段、分析研究可能出现的新的技术趋势、并结合国内外地下水封石油洞库研究的成果,简要提出地下水封石油洞库渗流场-应力场耦合作用机理研究的主要方向是渗流场和应力场耦合情况下的洞库稳定性、围岩岩石力学行为特征和岩石的流变损伤。

Petroleum and natural gas reserve has been promoted to strategy level in many countries.Groundwater-sealed oil storage cavern,as one of the main methods of crude oil reserves,has stepped into the implementation phase.This paper gives a review of domestic and international seepage-stress field interactive effects on groundwater-sealed petroleum storage caverns,the problems encountered in practical engineering,the major research methods,analyzing the possible emergence of a new technology trends,combined with the study results of domestic and international seepage-stress field interactive effects on groundwater-seal petroleum storage caverns.This paper briefly puts forward the main directions of the seepage-stress effect study,which includes the stability of the groundwater-seal petroleum storage caverns under the seepage-stress field interactive effects,the characteristics of the rock mechanics behavior,and rheological damage of rock.
