Abstract
Various downhole tools are discussed, including intake and gas separators for a downhole rotary pump. Multiple intakes configured in parallel and series are discussed, along with compact axial length gas separators, and gas separators that remove gas in novel ways. Related apparatuses and methods are discussed.
Claims112
A compact axial length gas separator stage of a downhole rotary pump comprising:
- a housing within which a fluid flowpath is defined;
- and
- a diffuser defining a gas crossover flowpath between a gas entry point and a gas outlet.
An intake stage for a downhole rotary pump comprising:
- an intake housing defining a fluid flowpath and an inlet hole to the fluid flowpath;
- and
- an impeller;
- in which the inlet hole is configured to expose at least a portion of an impeller vane of the impeller to an exterior of the downhole rotary pump.
An intake for a downhole rotary pump comprising:
- an intake housing defining a fluid flowpath and inlet holes to the fluid flowpath;
- an impeller;
- and
- a shaft extending through the intake;
- in which the inlet holes have a ratio, of the cumulative open flow area through the inlet holes to the flow area inside the intake housing, greater than 2.
A multi-stage intake of a downhole rotary pump defining a fluid flowpath and comprising two or more intake stages arranged in parallel, with two or more of the intake stages having one or more impellers.
