ABSTRACT:
A downhole fluid separation system is used with submergible pumping systems to separate downhole fluids into different density fluids, recover the lighter fluids to the earth's surface, and dispose the heavier fluids downhole. The fluid separation system includes a plurality of housings connectable one to another, each housing having one or more fluid separators, such as hydrocyclones, therein with an inlet of each fluid separator in communication with an inlet conduit, an overflow of each fluid separator in communication with an overflow conduit, and an underflow of each fluid separator in communication with an underflow conduit. The fluid separation system can be configured for parallel flow where the conduits conveying fluids downstream of a first housing have a greater cross-sectional flow area than corresponding conduits in an adjacent second housing. Also, the fluid separation system can be configured for series flow, for either the separated lighter or the separated heavier fluids. The use of differing sized conduits in the housings as required for the actual flow rates in each housing enable higher flow capacity fluid separators to be used than previously possible for greater fluid handling efficiency.
