Abstract

Abstract: Oil and gas development at home and abroad face the problem of low natural productivity of low permeability reservoirs. As it can effectively improve the recovery rate and reserve utilization rate of low permeability reservoirs, the multi-stage segmented fracturing technology today is one of the important means for the development of unconventional reservoirs. The fracturing sleeve is the core tool of multi-stage segmented technology. Major foreign companies have launched target-specific research and achieved many advanced results. In spite of a latecomer in this field, some domestic experts and scholars have proposed some characteristic techniques and tools. The author of this paper is poised to analyze the key technical principle of domestic and foreign fracturing sleeve and discuss the advantages and applicability of various relevant tools and processes with the purpose of laying a foundation for the development of fracturing sleeves in China.
