MODULAR HYDRAULIC PROTECTION OF SUBMERSIBLE MOTOR WITH EXTERNAL PORTS Russian patent published in 2020 - IPC E21B43/12 

FIELD: submersible pump systems.

SUBSTANCE: group of inventions relates, in particular, but without limitation, to a modular sealing section for use with a submersible pumping system. Guide element for use in sealing section inside well pump system is configured to be connected between upper fluid compensation section and lower fluid compensation section, available in sealing section, and containing configuration selection mechanism. At that, the configuration selection mechanism is configured to control it from the outside for selective arrangement of the said upper compensation section in the serial or parallel configuration with said lower compensation section. Said configuration selection mechanism has a set of passes and one or more plugs. Set of passes pass from upper compensation section to lower compensation section with provision of possibility to communicate inner space of lower section with its outer space and inner space of upper section and connection of outer space of lower section with inner and outer spaces of upper section. One or more plugs are installed inside corresponding one pass from specified set of passes.

EFFECT: technical result is higher efficiency of sealing section in parallel or serial configuration.
