| Abstract: | At present,horizontal well staged fracturing technology is the main technology to improve the recovery efficiency of low permeability,low pressure and low abundance unconventional oil and gas reservoirs through formation stimulation.To promote the development and application technology of horizontal well fracturing tools in China,the structure,working principle,application status and advantages and disadvantages of domestic and foreign horizontal well casing(annular)fracturing tools and tubing fracturing tools are introduced.The development direction of staged fracturing technology for horizontal wells in China is the development of downhole dissoluble fracturing tools,downhole intelligent identification and control sliding sleeve technology,and the multistage multi-well simultaneous fracturing technology.The development of high-quality and new fracturing tools and the reliability evaluation of downhole operation are of great significance to the development of synchronous fracturing technology. |
