Title: BELLOWS MOTOR EXPANSION CHAMBER FOR AN ELECTRIC SUBMERSIBLE PUMP
Abstract:
A bellows motor expansion chamber for electric submersible pumps (ESP). An ESP assembly includes an electric submersible motor between a thrust chamber and a motor expansion chamber, the motor expansion chamber including a bellows coupled to a releasable bellows anti-movement system including a heat-activated release and alterable between an immobilizing position, wherein the releasable anti-movement system prevents concertinaed movement of the bellows in the immobilizing position, and a released position, wherein the bellows is concertinaedly moveable in the released position, and wherein the releasable bellows anti-movement system is in the immobilizing position below a release temperature and in the released position above the release temperature. A filter section within a well fluid inlet of the bellows motor expansion chamber includes a least two concentric filters of varying porosity, and a housing surrounding the filters including angled ribs and flow holes.
