A multifunctional rotating control device (RCD) is provided. The multifunctional RCD includes an RCD assembly and a flow detection module. Further, the RCD assembly includes a body and a rotating sealing assembly. A bore through hole and a bypass outlet are formed in the body, and the rotating sealing assembly is provided in the bore through hole. Additionally, the bypass outlet is connected to a straight-through cut-off valve, and the flow detection module includes a flowmeter, a first flow cut-off valve, and a second flow cut-off valve. Further, the flowmeter extends upward in a direction of the bore through hole, and the first flow cut-off valve and the second flow cut-off valve are respectively provided at two ends of the flowmeter, and communicate with the flowmeter. Additionally, an inlet of the flowmeter is a flow detection input outlet, and the flow detection input outlet communicates with the straight-through cut-off valve.

Multifunctional rotating control device

A multifunctional rotating control device (RCD) includes an RCD assembly, a multi-way cross, and choke control modules. The RCD assembly includes a body and a rotating sealing assembly, where a bore through hole, two side outlets, and a straight-through outlet are formed in the body. The rotating sealing assembly is provided in the bore through hole, a straight-through cut-off valve is provided at the straight-through outlet, and there are two choke control modules. The two choke control modules are respectively connected to the two side outlets and the multi-way cross, and a side choke extends upward in a direction of the bore through hole. The two choke control modules are integrated onto the RCD assembly, and extend upward in the direction of the bore through hole.
