The invention relates to a deep-well oil-extraction external flow-channel direct and reverse circulation freely-throwing jet injector oil production method and a device. The oil production method comprises the following steps of: installing a pump cylinder with an external flow-channel under a well; and installing a direct circulation pump core during the direct circulation and installing a reverse circulation pump core during the reverse circulation, wherein no internal flow channel is formed in the direct circulation pump core and the reverse circulation pump core; during the direct circulation, power liquid absorbs formation liquid into the pump core through the external flow channel on the pump cylinder by a nozzle from the mouth of the well to the direct circulation pump core and after the power liquid is mixed with the formation liquid, the mixed liquid reaches the ground; and during the reverse circulation, the power liquid absorbs the formation liquid into the pump core through the external flow channel on the pump cylinder by the nozzle from the mouth of the well to the reverse circulation pump core and after the power liquid is mixed with the formation liquid, the mixed liquid reaches the ground. The method and the device have the advantages of realizing that the direct and reverse circulation production and liquid power freely throw the pump core, increasing the area of the flow channel because the formation liquid flows to the pump core from the external flow channel of the pump cylinder and increasing the theoretical yield of an oil well.

The invention relates to a fixed bed radial catalytic converter used for a gas-solid flow decrease/enthalpy increase chemical reaction, and concretely relates to a radial catalytic converter comprising a plurality of catalyst beds and having a plurality of flow forms. The radial reactor comprises a reactor housing, a support frame arranged in the reactor housing, a central cylinder positioned above the support frame, outer ring members coaxially arranged between the central cylinder and the reactor housing, and a plurality of inner ring members coaxially arranged between the central cylinder and the outer ring members.
