- the term "petroleum” refers broadly to all mineral hydrocarbons, such as crude oil, gas and combinations of oil and gas.
- the production tubing 102 connects the pumping system 100 to a wellhead 106 located on the surface.
- the pumping system 100 includes a pump 108, a motor 110, and a seal section 112.
- the pumping system 100 is primarily designed to pump petroleum products, it will be understood that the present invention can also be used to move other fluids. It will also be understood that, although each of the components of the pumping system are primarily disclosed in a submersible application, some or all of these components can also be used in surface pumping operations.
- upstream and downstream will be understood to refer to the relative positions within the pumping system 100 as defined by the movement of fluid through the pumping system 100 from the wellbore 104 to the wellhead 106.
- the term “longitudinal” will be understood to mean along the central axis running through the pumping system 100; the term “radial” will be understood to mean in directions perpendicular to the longitudinal axis; and the term “rotational” will refer to the position or movement of components rotating about the longitudinal axis.
- the motor 110 is an electric submersible motor that receives power from a surface-based facility through power cable 114. When electric power is supplied to the motor 110, the motor converts the electric power into rotational motion that is transferred along a shaft (not shown in FIG. 1) to the pump 108.
- the motor 110 is a three-phase motor that is controlled by a variable speed drive 116 located on the surface. The variable speed drive 116 can selectively control the speed, torque and other operating characteristics of the motor 110.
- the seal section 112 is positioned above the motor 110 and below the pump 108.
- the seal section 112 shields the motor 110 from mechanical thrust produced by the pump 108 and isolates the motor 110 from the wellbore fluids in the pump 108.
- the seal section 112 may also be used to accommodate the expansion and contraction of lubricants within the motor 110 during installation and operation of the pumping system 100.
- the seal section 112 is incorporated within the motor 110 or within the pump 108.
- the pump 108 is a rotary hydraulic pump that is driven by the motor 110.
- the pump 108 translates rotational motion produced by the motor 110 into linearly motion that drives reciprocating pistons within the pump 108.
- the pump 108 can be used in combination with additional pumps and motors.
- the pump 108 can be used with other hydraulic rotary pumps, to feed a surface-based sucker rod pump or to feed a centrifugal pump.
- the pump 108 utilizes a tilt-plate to translate the rotational movement of motor 110 into reciprocating linear motion.
- the pump 108 includes an upstream chamber 118, a downstream chamber 120 and a pump shaft 122. It will be appreciated, however, that the scope of exemplary embodiments is not limited to two- chamber designs.
- the pump 108 could alternatively include a single chamber or more than two chambers.
- the pump 108 further includes an intake 124, a discharge 126 and a housing 128. Each of the internal components within the pump 108 is contained within the housing 128. Fluid from the wellbore 104 enters the pump 108 through the intake 124 and is carried by the upstream and downstream chambers 118, 120 to the production tubing 102 through the discharge 126.
- the pump shaft 122 is connected to the output shaft from the motor 110 (not shown) either directly or through a series of interconnected shafts.
- the pump 108 may include one or more shaft seals that seal the shaft 122 as it passes through the upstream and downstream chambers 118, 120.
- Each of the upstream and downstream chambers 118, 120 includes a cylinder block 130, one or more piston assemblies 132 and a tilt disc assembly 134.
- the tilt disc assembly 134 includes a drive plate 136 and a rocker plate 138.
- FIGS. 5 and 6 illustrate the upstream face of the rocker plate 138 and the upstream face of the drive plate 136.
- the rocker plate 138 and the drive plate 136 may both be formed as substantially cylindrical members.
- the drive plate 136 is connected to the pump shaft 122 in a non-perpendicular orientation. In this way, rotation of the pump shaft 122 causes an upstream and a downstream edge of the drive plate 136 to rotate around the shaft 122 within the upstream and downstream chambers 118, 120 at opposite times.
- the drive plate 136 is connected to the pump shaft 122 at a fixed angle. In other embodiments, the angular disposition of the connection between the drive plate 136 and the pump shaft 122 can be adjusted during use.
- the rocker plate 138 is not configured for rotation with the pump shaft 122 and remains rotationally fixed with respect to the cylinder block 130 and housing 128.
- the upstream face of the rocker plate 138 is in sliding contact with the downstream face of the drive plate 136.
- the pump 108 includes a bearing between the rocker plate 138 and the drive plate 136 to reduce friction between the two components.
- the rocker plate 138 includes a central bearing 140 and piston rod recesses 142.
- the central bearing 140 permits the rocker plate 138 to tilt in response to the rotation of the adjacent drive plate 136.
- the central bearing 140 may include ball bearings, lip seals or other bearings that allow the rocker plate 138 to tilt in a longitudinal manner while remaining rotationally fixed.
- the cylinder block 130 includes a plurality of cylinders 144, intake ports 146 and one-way valves 148.
- the cylinder block 130 includes six cylinders 144, six intake ports 146, six intake way valves 148 and six discharge valves 150. It will be understood, however, that the cylinder block 130 may include different numbers of cylinders 144, intake ports 146 and one-way valves 148.
- the piston assemblies 132 include a piston rod 152 and a plunger 154.
- the pump 108 includes six piston assemblies 132. It will be understood, however, that fewer or greater numbers of piston assemblies 132 may also be used.
- a proximal end of each the piston rods 152 is secured within a corresponding one of the piston rod recesses 142 in the rocker plate 138.
- a distal end of each of the piston rods 152 is attached to the plunger 154.
- Each plunger 154 resides within a corresponding one of the cylinders 144.
- the intake ports 146 extend to the upstream side of the cylinder blocks 130.
- An intake valve 148 within the intake ports 146 allows fluid to enter the intake port 146 from the upstream side of the cylinder block 130, but prohibits fluid from passing back out of the upstream side of the cylinder block 130.
- a corresponding discharge valve 150 allows fluid to exit the cylinder 144, but prohibits fluid from entering the cylinder 144.
- the intake ports 146 extend through the downstream side of a single cylinder block 130.
- An intake valve 148 within the intake ports 146 allows fluid to enter the intake port 146 from the downstream side of the cylinder block 130, but prohibits fluid from passing back out of the intake port 146.
- a corresponding discharge valve 150 allows fluid to exit the cylinder 144, but prohibits fluid from entering the cylinder 144.
- the motor 110 turns the pump shaft 122, which in turn rotates the drive plate 136.
- the drive plate 136 rotates, it imparts reciprocating longitudinal motion to the rocker plate 136.
- the rocker plate 138 undergoes a full cycle of reciprocating, linear motion.
- the linear, reciprocating motion of the rocker plate 138 is transferred to the plungers 154 through the piston rods 152.
- the piston rods 152 force the plungers 154 to move back and forth within the cylinders 144.
- FIG. 8 shown therein is a cross-sectional depiction of the pump 108 constructed in accordance with another embodiment.
- the pump 108 uses a central camshaft 158 to drive one or more series of pistons 160 within banks of cylinders 162.
- the cylinders 162 are connected to manifolds 164 that extend the length of the pump 108.
- the pump 108 includes 2, 4, 6 or 8 banks of cylinders 162, manifolds 164 and series of pistons 160 that are equally distributed around the pump 108, as depicted in the top cross-sectional view of FIG. 9.
- the camshaft 158 includes a number of radially offset lobes 166 to which connecting rods 168 are secured for rotation.
- the camshaft 158 is connected directly or indirectly to the output shaft from the motor 110 such that operation of the motor 110 causes the camshaft 158 to rotate at the desired speed.
- the pistons 160, camshaft 158 and connecting rods 168 may include additional features not shown or described that are known in the art, including for example, wrist pins, piston seal rings and piston skirts.
- Each set of pistons 160 and connecting rods 168 can be collectively referred to as a "piston assembly" within the description of this embodiment.
- Each of the manifolds 164 includes an inlet 170 and outlet 172 and one or more check valves 174.
- the inlets 170 are connected to the pump intake 124 and the outlets 172 are connected to the discharge 126.
- each manifold 164 includes a separate check valve between adjacent pistons 160.
- the check valves 174 prevent fluid from moving upstream in a direction from the outlet 172 to the inlet 170. In this way, the check valves 174 separate the manifolds 164 into separate stages 176 that correlate to each of the pistons 160 and cylinders 162.
- the camshaft 158 rotates and causes the pistons 160 to move in reciprocating linear motion in accordance with well-known mechanics.
- a piston 160 retracts from the manifold 164, a temporary reduction in pressure occurs within the portion of the manifold 164 adjacent to the cylinder 162 of the retracting piston 160.
- the reduction in pressure creates a suction that draws fluid into the stage 176 from the adjacent upstream stage 176 through the intervening check valve 174.
- the piston 160 moves through the cylinder 162 toward the manifold 164, thereby reducing the volume of the open portion of the cylinder 162 and stage 176.
- camshaft 158 can be optimized to produce suction-compression cycles within each stage 176 that are partially or totally offset between adjacent stages 176 that provide for the sequential stepped movement of fluid through the manifolds 164.
- the pistons 160 are configured to extend into the manifold 164.
- the check valves 174 are omitted and the progression of fluid through the manifold 164 is made possible by holding the pistons 160 in a closed position within the manifold 164 to act as a stop against the reverse movement of fluid toward the inlet 170.
- the timing of the pistons 160 can be controlled using lobed cams and rocker arms as an alternative to the camshaft 158 and connecting rods 168. In this way, the pistons 160 produce rolling progressive cavities within the manifolds 164 that push fluid downstream through the pump 108.
- the pump 108 provides a positive displacement, linearly reciprocating pump that is powered by the rotating shaft of a conventional electric submersible motor 110.
- the pump 108 will find particular utility in lower volume pumping operations and in wellbores 104 that present fluids with a large gas fraction. Because the pump 108 can be configured to be shorter than conventional multistage centrifugal pumps, the pump 108 is also well- suited for deployment in deviated (non-vertical) wellbores 104.
