The connecting plate on the nut and the traveling and fixing kit move up and down in the slide groove of the auxiliary rod. The traveling and fixing kit drives the blowout preventer 1 to move up and down, realizing the riser operation. Then, the test instrument can be installed or removed by flipping the blowout preventer 1. Before use, first install the fixing sleeve of the blowout preventer 1, then connect the test electric environmental protection plug and the connecting union 29 instrument lock assembly to the upper and lower parts of the blowout preventer 1, and install the sealing packing of the environmental protection plug.

[0030] First, install the test valve assembly onto the wellhead. Quickly connect and fix the insert plate on the electric lifting auxiliary rod assembly to the slot on the test valve assembly. Connect the blowout preventer 1 travel fixing kit to the quick plug on the electric lifting auxiliary rod assembly. Install the test instrument and control power cable. Turn on the power through the rise button in the electric control box assembly to make the high-power motor of the electric lifting auxiliary rod assembly rotate, which drives the screw rod to rotate. This causes the travel threaded pipe, function plug 20, and blowout preventer 1 to be lifted to the working position simultaneously. Then, connect the union 29 and the pulley to complete the riser operation.

[0031] After opening the balance gate on the test valve assembly and closing the air-raid shelter gate, manually pull the logging wire to strike the instrument lock to reverse and unlock it. Slowly release the winch brake and lower the instrument to the flap of the test valve assembly. At this time, under the action of the instrument's gravity, the flap is pressed open and the instrument is lowered into the well. The overflow flow rate of the electric environmental protection plug is controlled by the remote control, and the overflow water is introduced into the collection tank.

[0032] After the instrument enters the blowout preventer 1, manually pull the logging wire to move the instrument and strike the instrument lock to reverse and lock the instrument. Close the balance gate and flap valve on the test valve assembly, open the control gate to release the sewage in the pipe, and then open the union 29. By manually pulling the logging wire to strike the instrument lock to reverse and unlock it, the instrument can be slowly released.
