Research Status and Prospects of Key Technologies for Underground Water-sealed Oil Storage Cave

Abstract

Abstract Petroleum is the lifeblood of the national economy. The underground water-sealed oil storage cave has become the main development direction and research object of petroleum reserve at home and abroad due to its advantages. This paper summarizes the research progress of key technologies for large-scale underground water-sealed oil storage cave, emphasizes the current role of underground water-sealed oil storage cave in petroleum reserve, and discusses water curtain system and water sealing, surrounding rock permeability and evaluation, surrounding rock stability and evaluation, field construction technology and related issues, and also emphasizes the importance of strategic petroleum reserve(SPR), and has prospects to the future development of underground water-sealed oil storage cave.
