The present invention is a hydraulic control apparatus that activates and deactivates a downhole tool, such as a reamer, at a desired downhole location in a borehole. The apparatus includes a piston, a housing, a coil spring, and a guide pin. The piston has a cam portion with a continuous slotted groove. There is a slide member and a force member within the slotted groove so that the piston moves longitudinally and rotationally within the housing according to the guide pin within the slotted groove. At the desired downhole location, drilling fluid pressure passes a pressure threshold to move a front outlet of the piston to an opened position past an end of the housing, while rotating the piston according to the slide member and force member in the slotted groove. The apparatus alternately extends and retracts the reamer by opening and closing the front outlet by hydraulic control.

The present application provides a hydrophilic and hydrophobic composite packing-based rotating packed bed and a system. A hydrophobic packing and a hydrophilic packing are formed into a composite packing. When said packing cuts liquid, the hydrophobic packing can sufficiently disperse the liquid so as to make the dispersion of the liquid in the packing zone more uniform, and the wettability of the hydrophilic packing allows the liquid to spread sufficiently so as to increase the wetting efficiency of said packing. The phenomenon of droplet aggregation caused to liquid in a single hydrophobic packing zone and the phenomenon of reduction of liquid turbulence caused to liquid in a single hydrophilic packing zone can be avoided. Therefore, applying a hydrophilic and hydrophobic composite packing to a rotating packed bed can further improve the mass transfer and mixing performance thereof.

The present application provides a high-gravity device for generating nano/micron bubble and a reaction system. In the device, the liquid phase is continuous phase and the gas phase is dispersed phase. A gas enters the interior of the device from a hollow shaft, and the gas is subjected to primary shearing under a shearing effect of aerating micropores to form bubbles; then, the bubbles rapidly disengage from the surface of a rotating shaft under the effect of the rotating shaft rotating at a high speed, and are subjected to secondary shearing under the high-gravity environment with the strong shearing force formed by the rotating shaft to form nano/micron bubbles. The device has the advantages of fastness, stability, and small average particle size. The average particle size of the formed nano/micron bubbles is between 800 nanometers and 50 microns, and the average particle size of the bubbles can be regulated in a range by adjusting the rotating speed of the rotating shaft.
