Orbital downhole separator

A downhole fluid separator comprising:

• a housing adapted to connect to a tool string;
• a rotating member disposed in the housing and defining a flow passage, wherein fluid flowing through the rotating member is subjected to centrifugal force such that the fluid is separated into heavier and lighter components, and the rotating member comprises an inner cylindrical member and an outer cylindrical member and the flow passage is formed in an annular space between the inner and outer cylindrical members;
• a flow conditioner comprising a longitudinal baffle disposed in a flow passage along substantially an entire length of the rotating member, where the baffle is one of a plurality of angularly shaped baffles extending radially in the flow passage between the inner and outer cylindrical members;
• a first passage to direct a first component of the fluid toward a first direction;
• and
• a second passage to direct a second component of the fluid toward a second, opposite direction
• wherein the first passage is formed through an interior of the inner cylindrical member and is in communication with the flow passage.

A downhole fluid separator comprising:

• a housing adapted to connect to a tool string;
• a cylinder rotatably disposed in the housing and defining a flow passage therein;
• a flow conditioner comprising a longitudinal baffle disposed in the flow passage extending along a length of the cylinder, wherein fluid flowing through the housing enters the flow passage and is subjected to centrifugal force such that the fluid is separated into different components having different specific gravities;
• an outer cylinder rotatable with the cylinder, wherein the cylinder, the outer cylinder, and the baffle are rotatable together;
• a first passage to direct a first component of the fluid toward a first direction;
• and
• a second passage to direct a second component of the fluid toward a second, opposite direction.
