Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Specifically, when drilling, the staff will debug the drilling equipment, select the rod body 8 according to the design requirements of the drilling, and then connect the connector 1 to ensure that the connection is firm and the thread seal is good. The external thread 2 on the connector 1 can be used to connect with the bottom of the next rod body 8, and the connector 1 is conical in shape. The cones are connected to each other and will produce a certain self-tightening force after assembly, making the connection between the two sections of the drill pipe tighter and firmer. The top and bottom ends of the connector 1 are provided with a first sealing gasket 3 and a second sealing gasket 5. The first sealing gasket 3 and the second sealing gasket 5 can effectively prevent liquid leakage when connected to other drill pipes, and can play a sealing role in high-pressure or low-pressure environments, and infusion The tube 4 is connected to the inside of the rod body 8, and the bottom end of the rod body 8 is provided with a connection port 10 and an internal thread 11, which is connected to another connector 1 through the internal thread 11, and another infusion tube 4 can be inserted into the inside of the connection port 10 to provide a flow path for the liquid circulating inside.

Then, the connector 1 will be connected to ensure a firm connection and good thread sealing. The external thread 2 on the connector 1 can be used to connect to the bottom of the next rod body 8. The connector 1 is conical in shape. The cones are connected to each other and will generate a certain self-tightening force after assembly, making the connection between the two drill pipes tighter and firmer. The top and bottom ends of the connector 1 are provided with a first sealing gasket 3 and a second sealing gasket 5. The first sealing gasket 3 and the second sealing gasket 5 can effectively prevent liquid leakage when connected to other drill pipes. They can play a sealing role in high-pressure or low-pressure environments, and infusion The tube 4 is connected to the interior of the rod body 8, and the bottom end of the rod body 8 is provided with a connecting port 10 and an internal thread 11, which is connected to another connector 1 through the internal thread 11, and another infusion tube 4 can be inserted into the interior of the connecting port 10 to provide a flow path for the liquid circulating inside. Multiple sections are connected together to form a pipeline for liquid circulation. When the drilling operation continues, in order to avoid damage to the rock and soil layer to the rod body 8, the friction of the rod body 8 can be reduced by the wear-resistant ring 7, which bears most of the friction. When drilling into the well wall, the wear-resistant ring 7 can be used for buffering to reduce damage to the well wall. During the drilling process, the rotating thread 6 can also be used to assist in entering the well. The rotating thread 6 can reduce the resistance of drilling during rotation.
