The inner pipe is made of a corrosion-resistant material and is located inside the outer pipe. The bimetallic composite pipe further includes a connecting part, which is connected to the outer pipe by a thread, and the inner pipe is welded to the connecting part. The bimetallic composite pipe with a threaded connection form between the connecting part and the outer pipe avoids the decrease in welding strength caused by dissimilar metal welding, ensuring the connection performance of the oil well pipe string; at the same time, the inner pipe made of a corrosion-resistant material ensures that the corrosion medium inside the pipe does not contact the outer pipe, ensuring the safety of the use of the bimetallic composite pipe.
