External oil expansion chamber for seabed boosting ESP equipment |
摘要 |
An expansion chamber to serve ESP equipment installed on the seabed located in either a caisson or a conduit on a skid. The expansion chamber provides an external reservoir for expansion and contraction of motor oil in the ESP equipment. During operation of an ESP, the heat generated in the motor raises the temperature of the motor oil, causing it to expand. The expansion chamber is connected to the ESP equipment via oil lines that allow oil to expand into the expansion chamber when the temperature of the motor oil increases. The expansion chamber has a movable barrier therein that defines primary and secondary chamber. Oil communicates with the primary chamber. Formation fluid within the conduit surrounding the motor communicates with the secondary chamber.
