摘要： A technique facilitates removal of gas from a gas-sensitive region in an electric submersible pumping system. A gas purging system is integrated into the electric submersible pumping system. During operation of the electric submersible pumping system, the gas purging system also is operated to move gas away from the gas-sensitive region, e.g. a thrust bearing region, and to a collection region or other suitable region. In some embodiments, the gas which accumulates in a collection region may be discharged to a region external of the electric submersible pumping system.

摘要： A system and methodology facilitate connection between components of an electric submersible pumping system. The technique utilizes at least one connector designed to connect a first component to a second component of an electric submersible pumping system. The connector is designed as a flangeless connector which secures engagement of the two components without relative rotation between the first component and the second component. Additional flangeless connectors may be positioned between other pairs of components to provide the enhanced connection throughout the electric submersible pumping system.

摘要： Wear rings for electric submersible pump (ESP) stages are provided. An example ESP has one or more running clearance seals reinforced with high-hardness wear rings. Ceramics and carbides may provide the high hardness for the wear rings, but such substances are more brittle than metals and have different coefficients of thermal expansion than metals. For protection, each high-hardness wear ring may be mounted with an elastic cushioning scheme. The elastic mounting preserves each wear ring from shock, stress, and breakage from thermal expansion and contraction of an adjacent pump part. Each high-hardness wear ring may also have a low-stress driving mechanism that cushions the rotational force imparted to the wear ring when the ESP pump is being powered. In some implementations, the elastic mounting scheme may also serve as the low-stress driving mechanism for the high-hardness wear ring.

摘要： An electric submersible pump (ESP) with reduced vibration is provided. In an implementation, an ESP section has radial bearings placed at shaft locations of reduced vibration to reduce wear. The locations of reduced vibration are selected to avoid areas of high vibration and vibrational waves that reinforce each other due to structure resonance and natural excitation frequencies. In an implementation, a radial bearing is positioned at a node of reduced vibration of a standing vibrational wave. In an implementation, a succession of multiple radial bearings are spaced at different intervals from each other to avoid conventional even spacing of the bearings that causes standing waves, resonance waves, and vibrational waves at natural excitation frequencies. In an implementation, a span between adjacent radial bearings is selected to spare other adjacent bearings at different spans the effects of vibrations that may extend over a range of excitation frequencies in the ESP section.
