A submersible pumping system has an electric motor, a rotary hydraulic pump driven by the electric motor, and a linear hydraulic pump that is configured to move a production fluid. The rotary hydraulic pump produces a pressurized working fluid that drives the linear hydraulic pump. In another aspect, a method is disclosed for controlling the temperature of an electric motor within a submersible pumping system disposed in a wellbore. The method includes the steps of circulating motor lubricant through a hydraulically driven production pump to reduce the temperature of the motor lubricant.

Linear hydraulic pump for submersible applications

A pumping system includes a motor, a shaft driven by the motor, a pump driven by shaft, a thrust bearing housing and a thrust bearing assembly contained within the thrust bearing housing. The thrust bearing assembly includes a rotating component connected to the shaft, a first bearing adjacent to the rotating component and an adjustment mechanism for the adjusting the distance between the rotating component and the first bearing. The adjustment mechanism can be externally manipulated from outside the thrust bearing housing.

An adapter is used to connect a first component within a downhole pumping system to a second component within the downhole pumping system. The adapter includes an upstream section adjacent the first component and a downstream section adjacent the second component. The adapter further includes an articulating joint that permits the angular movement of the first component with respect to the second component. The articulating joint includes a flexible metal casing extending between the upstream section and the downstream section.

Flexible joint connection

A downhole manifold assembly includes a manifold body defining a longitudinal axis and having a first end face, a second end face, and an outer surface extending therebetween. A fluid circuit is defined in the manifold body and includes a plurality of axially extending fluid passages and a plurality of radially extending fluid passages. The radially extending fluid passages extend to the outer surface of the manifold body. Each radially extending fluid passage defines a respective aperture in the outer surface. The manifold assembly also includes a control valve coupled to the manifold body. The control valve is positionable between a first position in which a flow of pressurized fluid is channeled through the fluid circuit in a first direction, and a second position in which the flow is reversed and the pressurized fluid is channeled through the fluid circuit in a second direction.

A modular seal section for use within a downhole pumping system includes an upper fluid compensation section, a lower fluid compensation section and a guide body connected between the upper fluid compensation section and lower fluid compensation section. The guide body includes a configuration selection mechanism that can be externally manipulated to selectively place the upper fluid compensation section in either a series or parallel configuration with the lower fluid compensation section.

A downhole submersible pumping system includes an adapter for use in connecting a first component to a second component within the downhole pumping system. The adapter preferably includes an upstream section configured for connection to the first component and a downstream section configured for connection to the second component. The adapter further includes an articulating joint that permits the angular movement of the first component with respect to the second component.

A thrust section for use above a motor preferably includes a housing, a thrust shaft, a thrust runner connected to the thrust shaft, a thrust bearing connected to the housing, and a motor lead guard. The motor is preferably positioned above a pump assembly. The thrust runner and thrust bearing prevent upward movement of the shaft.
