Downhole Inductive Coupler for Wireless Power and Data Transmission

The patent replaces the mechanical connection system (physical cable connection requiring pressure testing) with an electromagnetic induction system. The transmitter coil on the tubing string generates an electromagnetic field that inductively couples to the receiver coil in the sensor, eliminating the need for physical cable connections and pressure testing at the surface. This substitution resolves the contradiction by maintaining connection reliability through electromagnetic coupling while eliminating the time-consuming mechanical connection and testing processes.

The patent introduces electromagnetic fields as an intermediary between the cable and sensor. Instead of direct physical contact, the transmitter coil generates an electromagnetic field that serves as a mediator to transfer power and signals to the receiver coil. This intermediary approach maintains reliable energy and data transfer while eliminating the need for mechanical connection and pressure testing, thus reducing rig time.

The patent replaces the mechanical connection system with electromagnetic induction, allowing sensors to be installed on the tubing string without requiring pauses for connection testing. The inductive coupling provides safe and reliable connection without physical contact, enabling continuous run-in-hole operations and improving productivity while maintaining connection safety.

The patent enables continuous run-in-hole operations by eliminating the need to pause for sensor installation and pressure testing. The electromagnetic induction system provides continuous power and data transmission without requiring intermittent stops, thereby maintaining continuous productive action and improving overall productivity.

The patent replaces the complex mechanical cable connection system with a simple electromagnetic induction system. The transmitter coil on the tubing string and receiver coil in the sensor create an inductive coupling that provides reliable electrical connection without requiring physical cable attachment, installation pauses, or pressure testing. This substitution significantly reduces installation and testing complexity while maintaining electrical connection reliability.

The patent extracts the physical cable connection requirement from the sensor installation process. By using electromagnetic induction, the system separates the electrical connection function from the mechanical connection function, allowing sensors to be installed on the tubing string without requiring physical cable attachment or subsequent testing procedures, thereby reducing overall system complexity.
