POWER EFFICIENCY IMPROVEMENT OF ESP SYSTEM:PUMP STAGES OF IMPROVED HEAD-FLOW AND POWER CHARACTERISTICS
11
ESP power efficiency improvement, application of new corrosion-wear resistant material: PUMP STAGES— ORIGINAL DESIGN
Pump stages are manufactured by classic casting of Ni-resist to provide their high corrosion resistance. For especially «hard» production conditions we provide special chemical composition of Ni-resist alloy structure ЧН16Д7ГХ2Ш, hardness hereof is increased to 190-240 НВ. Dimensions of working parts are the same, interchangeability is safe.
Stages of double-base design
Vortex of original design is added in the impeller of centrifugal stage to provide improvements as follows:
— stage head is increased up to 25% in comparison with standard stage;— stage efficiency is increased by 5–7% in comparison with standard stage;— axial load to impeller is reduced — as a consequence improved wear-resistance in
impeller bases;— rated free gas volume is increased by 7% in comparison with standard stage.
12
We offer four principal pump assembly schemes for various operating conditions —
Shaft bearing is in pump section;
impeller bases are based upon diffuser;
hydroprotector thrust bearing takes
loads of its own shaft (2215 design)
Compression assembly — shaft thrust bearing and bases of impeller are in hydroprotector (0615 design)

Impellers freely move on the shaft along the axis at allowable clearance, providing easy assembly and not requiring making extra accuracy stages
No need to adjust outlet distance of shafts
Axial bearing and support washers of impellers are subject to abrasive wear. It is recommended to use in operating conditions with max. solids concentration 0,5 g/l
PUMPS — FLOATING STAGES WITH SHAFT AXIAL BEARING
14
PUMPS — FLOATING STAGES WITH NO SHAFT AXIAL BEARING
Shaft axial bearing is installed in hydroprotector and not subject to wear
Impellers freely move on the shaft along the axis at allowable clearance, providing easy assembly and not requiring high precision of stages during repair
Minimum cost of manufacture
During assembly of sections the shaft depth into head is determined as equal to shaft outlet distance from the base side by means of the adjusting screw and washers
Support washers of impellers are subject to wear. It is recommended to use in operating conditions with max. solids concentration 0,5 g/l
15
PUMPS — PACKET ASSEMBLY
Impellers are assembled in packets. Axial load from impellers are taken not by support washers, but by packet axial bearing — unloaded support washers are less subject to wear
It is recommended to use in operating conditions with high solids concentration 1 g/l
No need in adjustment during pump repair
16
Hydrodynamic axial bearing of shaft is installed in hydroprotector,it has low friction coefficient and not subject to wear
It is recommended to use in operating conditions with high solids concentration 1 g/l
Impellers are tightened by a nut in one packet and fixed on the shaft to avoid axial movement. The shaft is in strained tension condition
In the process of pump operation axial force is born by the axial bearing. At the same time shaft compression is compensated by their pretensioned condition, preventing longitudinal bending and, consequently, one-sided wear of shafts, impellers and diffusers
PUMPS — COMPRESSION ASSEMBLY DESIGN WITH NO AXIAL BEARING
17
NEW SOLUTIONS — ASSEMBLY TIME REDUCTION
No need to perform labour-intensive operation of the shaft outlet distance adjustment during pump assembly. Contact of pump section shafts is provided by adjusting screw which is fixed by coupling to prevent turning-off and does not require additional locking devices. Screw is adjusted by the special device using no measuring tools.ESP assembly time is half reduced.

MAIN FEATURES OF NEW PUMPS
Availability of radial bearings in the heads and bases provide reduction of the shaft cantilevers, increasing the shaft end radial stiffness
Optimum positioning of the radial intermediate bearings along the pump
sections provides improvement of the shaft radial stiffness, resulting in the decreased level of vibration and increased life time of ESPs that can be applied in highly abrasive mediums
Evolvent shaft spline joint allows increasing maximum acceptable power for 20%. A shaft is made of a high-strength steel. The shaft overhang adjustment system is provided in the section design.
Coupling is removed from the base to the section head to increase area of passage and и decrease the pump hydraulic resistance. No stress raisers in the coupling in a form of holes for a pin.
The impellers design is notable for an extra blade row in the top disc, reducing axial force, efficiently dispersing gas-fluid mixture, that allows increasing
permissible content of free gas for 7% at pump intake, increasing efficiency and head
Self-swelling annular rubber rings are applied in a section to ease assembly-dissasembly of sections. The intake module of unified design in a pump allows assembly with any type of hydroprotector made by ALNAS.

ALSU control systems main features
ALSU control system features:
• user-friendly interface;• wide range of performances; • high reliability;• control software flexibility;• smart control of well bore and reservoir flow.
Customer benefits:
• reduction of operating costs due to early detection of deviations in the equipment operation and procedures to avoid emergencies;
• reduction of electricity charges due to a function of the SEM required power optimization;
• reduction of costs for the control systems and oil-field equipment service;
• reduction of the equipment down-time;• effective oil pools operation due to the on-line inspection of the well fluid characteristics
and correction of the oil-field equipment operating mode;• reduction of costs for additional telemetry equipment.

ALSU CONTROL SYSTEMS FEATURES
Due to modular design the control systems can be completed with any electric motor control systems:
• direct start with soft start option;• VSD control systems to regulate the induction and permanent
magnet motors speed;• downhole and wellhead telemetry systems.
Smart control: The control system provides calculation of the main parameters of the "layer-well-
pump" system, e.g., flow rate and dynamic head, diagnostics and ESP mode optimization if VSD-
completed.
Information read-out: Remote accessing and information read-out by interface RS-485 or automatic read-
out of the operation history record by USB Flash, 8Gbit.
43
Unified units and upgradability
Easy interface:A large monitor, comprehensible interface allow getting any
information required, or setting up the control system.
Easy to monitor the control system status: LED indicators, e.g. "Power", "SEM", "Mode", "Failure", allow
determining the control system current status.
Easy to maintain: Modular design provides fast serviceability in operation area.
Compatibility: The control systems are compatible with the downhole telemetry
systems of ALNAS, Electon, Borets, IP3, WG.
Teleautomatics protocol support:The control systems are compatible with the teleautomatics
systems “Region 2000” and “Telescope+”.
Easy to update: Modular assembly allows updating and adding hardware and
software tools.
