Abstract: Disclosed is a method for reducing pressure and increasing injection by continuous operation system of biological acid acidification and nano coating, specifically including composition and preparation method of biological acidizing agent and nano coating agent. The method for reducing pressure and increasing injection by continuous operation system of biological acid acidification and nano coating of the present disclosure is able to effectively dredge the stratum water flow channel, reduce the water flow resistance, and achieve the effect of high-efficiency pressure reduction and injection increase of the water injection well.

Abstract: A magnetron drive mechanism is provided. The magnetron drive mechanism includes: a driving assembly, a rotating assembly, a transmission assembly, and a limiting assembly. The driving assembly is configured to drive the rotating assembly and the transmission assembly to rotate clockwise or counterclockwise around a first rotation axis. The rotating assembly is connected to a magnetron, and through the transmission assembly, the driving assembly drives the rotating assembly and the magnetron to rotate clockwise or counterclockwise around a second rotation axis. The second rotation axis and the first rotation axis are parallel with each other. The limiting assembly is configured to block the rotating assembly from rotating clockwise or counterclockwise, respectively, to confine the magnetron to positions at different radii of the first rotation axis. The present disclosure also provides a magnetron assembly and a reaction chamber.

Abstract: The present disclosure provides a pre-cleaning chamber. The pre-cleaning chamber includes a cavity, a top cover of the cavity, and an ion filtering unit with venting holes. The ion filtering unit is configured to divide the cavity into an upper sub-cavity and a lower sub-cavity and to filter out ions from plasma when the plasma is moving through the filtering unit from the upper sub-cavity to the lower sub-cavity. The pre-cleaning chamber further includes a carry unit located in the lower sub-cavity for supporting a wafer.
