    摘要： A petroleum well for producing petroleum products that incorporates a system adapted to provide power to a downhole device in the well. The system includes a current impedance device and a downhole power storage device. The current impedance device is positioned such that when a time-varying electrical current is transmitted through the portion of a piping structure and/or a voltage potential forms between one side of the current impedance device and another side of the current impedance device. The device is adapted to be electrically connected to the piping structure and/or across the voltage potential formed by the current impedance device, is adapted to be recharged by the electrical current, and is adapted to be electrically connected to the downhole device to provide power to the downhole device as needed.

    摘要： A petroleum well having a well casing, a production tubing, a source of time-varying current, a downhole chemical injection device, and a downhole induction choke. The casing extends within a wellbore of the well. The tubing extends within the casing. The current source is located at the surface. The current source is electrically connected to, and adapted to output a time-varying current into, the tubing and/or the casing, which act as electrical conductors for providing downhole power and/or communications. The injection device having a communications and control module, a chemical container, and an electrically controllable chemical injector. The communications and control module is electrically connected to the tubing and/or the casing. The chemical injector is electrically connected to the communications and control module, and is in fluid communication with the chemical container. The downhole induction choke is located about a portion of the tubing and/or the casing. The chemical injector is electrically connected to the communications and control module, and is in fluid communication with the chemical container. The downhole induction choke is located about a portion of the tubing and/or the casing. The induction choke is adapted to route part of the electrical current through the communications and control module by creating a voltage potential between one side of the induction choke and another side of the induction choke. The communications and control module is electrically connected across the voltage potential. Also, a method is provided for controllably injecting a chemical into the well downhole, which may be used to: improve lift efficiency with a foaming agent, prevent deposition of solids with a paraffin solvent, improve a flow characteristic of the flow stream with a surfactant, prevent corrosion with a corrosion inhibitor, and/or prevent scaling with scale preventers.
