Abstract: A high-frequency composite impactor including a high-frequency axial and a torsional impact assembly is disclosed. The high-frequency axial impact assembly includes an upper self-excited oscillation cavity, a lower self-excited oscillation cavity, an adjustment block and a lock nut. The torsional impact assembly includes an upper end cover, a reversing switch, a pendulum, a lower shell, a lower end cover, a nozzle, a connecting block and a retaining ring. The high-frequency axial impact assembly converts the flowing drilling fluid into a pulsed jet to achieve a high-frequency axial impact. The torsional impact assembly enables a torsional impact through a shunt, and finally enables a high-frequency composite impact, which can effectively reduce the stick-slip of the drill string, jump drilling and other downhole accidents. By reducing the friction between the drill string and the borehole wall, the impactor can reduce WOB loss, increase the ROP, and improve the drilling efficiency.

Abstract: An oil and gas fracturing tool is disclosed, mainly involving a fracking tool with an electromagnetic intelligent control sliding sleeve including an outer sleeve section, a dart body section and a control section. The outer sleeve section is at the target location to be fractured. The effect of fracturing is mainly achieved by the dart body, which has an activated state and an inactive state. The initial state is inactive, and the front locking tip can be deformed under pressure during displacement. The diameter can change to pass through any sliding sleeve. When the dart body is counted and is about to reach the fracturing position, the front locking tip is blocked from deformation and cannot be reduced in diameter, thus pressurizing to control the fracturing effect. The control part includes a sensor module, a drive module, a main control module and a power supply module.
