10 ABOUT ALNAS Pumps
SUBMERSIBLE CENTRIFUGAL PUMPS (ESP)
The Alnas pumps are designed using sectional principle and consist of upper section (with fishing head for fastening pump to tubing string), midsections, intake module, gas separator, and check valve and bleeder valve.
Check valves have high tightness permitting to conduct coil tubing pressure/leak test. Check valves design may be poppet valve type or ball type (option by request).
Intake module may be provided with pump section as a whole to lower a number of connections. In that case, the pump unit (complete) has a lower stage provided with perforations for liquid intake.
Intake submersible wire filter can also be used for submersible pumps to take formation fluid and separate solid particles with cross-section of 0.1 or 0.2 mm. For detailed filter data, see Page 21.
At high gas content in formation fluid, complete pump may include a gas separator. When PPFA is included, gas separator is made w/o intake openings.
Pump section length is varied to provide optimal pump selection for any wellbore length. Intermediate radial bearings are installed along the section (see fig). Reliable and long pump operation under various operating conditions is provided by optimum distance between radial bearings.
Impeller and guide vane materials developed by leading specialized institutes are as follows:
Modified gray cast-iron (standard design Alnas ESP pumps)
Modified cast-iron of enhanced wear resistance (ESPW type pump wear resistant types) intermediate ball check valve Ni-resist type iron (ESPC pump corrosion resistant type and bearing ESPCW pump corrosion and wear resistant type)
Hard Ni-resist type iron with max hardness of HB 240 (enhanced corrosion and wear resistance pumps)

11 ABOUT ALNAS Pumps
DOUBLE-SEAT DESIGN PUMPS
Application of ESP with "double-seat design" pump stages allows pump operation at arduous conditions with high solids content. This stage design provides significantly enhanced mean-time-between-failures for the ESP pumps.
High service life of "double-seat design" pump is conditioned by considerably lower friction loading per unit area of impellers The stages are extended in both sides, which allows to:
• Reduce vibration (impeller stability enhanced due to multiple increased impeller fit length on a shaft) • Hidden shaft providing its protection from formation fluid hydroabrasive effect • Practically eliminate wedge key cutting and stage to shaft turning (impeller key slot length is multiply increased to minimize key load). Special materials used for operating in conditions of hydroabrasive wear – pump stages are made of Ni-resist or modified (non- corrosion resistant) cast-iron of enhanced wear resistance.
Complete set of tools and accessories for in-field mounting & installation are available for order. All necessary spare parts can be supplied in any amount required.
PUMPS WITHOUT AXIAL BEARING SHAFT
These pumps features are as follows:
• Axle loading transmitted by pump shaft is sustained by reinforced seal section thrust bearing assembly • Mounting & installation is simplified as compared to competitors • Section hydraulic efficiency is enhanced due to pump stage quantity increased • Pump shaft cantilevers are reduced • Section hydraulic efficiency is enhanced due to shaft axial bearing transferred from pump section to seal section cave and in- creased number of pump stages in pump sections
Pumps without shaft axial bearing have the following advantages:
• Pump operating elements are of Ni-resist iron or Ni-resist type austenitic cold pig iron with hardness of HB 190 to 240 (option by request) • Radial bearings are manufactured using hard alloys • Lower pump vibration level and radial bearings loading due to reduced shaft cantilevers
PUMPS WITH PACKET STAGE ASSEMBLY
Alnas offers pumps with packet stage assembly, enhanced corrosion and wear resistance, designed for reservoir fluid production in diffi- cult operating conditions.
This pump type features are as follows:
• Pump sections without shaft axial bearing (transmitted shaft axle loading is sustained by thrust bearing). • Packet stage assembling provides axial and radial support for every packet of stages • Operating elements of single pad design w/ extended hub • Impeller hubs contact each other and transfer axle loading to radial-axial support installed in stage packet lower part • Shaft overhang is reduced relative to radial bearing • Due to reduced base overall dimensions, the protective ribs for cable extension are removed from the base to the head
The benefits of pumps with packet stage assembly are as follows:
• Pump operating elements are of Ni-resist type austenitic cold pig iron, with hardness of HB 190 to 240, and high corrosion resistant • Radial bearings are manufactured using hard alloys • Low impeller washers wear • Due to reduced shaft cantilever, pump unit total vibration level is reduced • Protective ribs located in the head allow for cable protection from the very top of the section.

15 ABOUT ALNAS Gas separators
PPFA SUBMERSIBLE WIRE FILTER
Purpose and Principle of Operation
PPF submersible wire filter is designed to protect ESP from ingress of solids, formation fluid propping agent particles with cross-section over 0.1 mm (particles content up to 3 g/l). Formation fluid is filtered when flowing through the filtering element slotted screens. Gravity and vibration effect results in filter self-cleaning during operation. Filtration degree is defined by the slot size. Bearing assembly uses bushings of hard alloy. At both sides of movable bush on the shaft, the forced cooling device for a bearing pair is provided to eliminate overheating of the bearing. PPF submersible wire filter can be equipped with one or several sections selected depending on pump throughput. PPF is to be installed between seal section and pump lower section or between seal section and gas separator (w/o intake module).
Basic benefits:
• Using as ESP unit component • Repairability • Filtration degree is 0.1 mm or 0.2 mm • High strength and durability of the filter • Clog-proof, self-cleaning filtering elements • Radial bearing of hard alloy use • Bearing forced cooling
16 ABOUT ALNAS Gas separators
GAS SEPARATORS, DISPENSERS
Gas separators, dispensers, and gas separator-dispensers are designed to ensure electrical centrifugal pump steady operation when pumping out formation fluid having high gas void fraction.
Gas separator is essential when oil production well has high dissolved gas content. For installation at pump inlet instead of intake module or after intake module in a gas separator model w/o intake screen. Alnas produces and delivers effective gas separators for all types of pumps and for various operating conditions.
Gas separator operating principle is based on using centrifugal force for free gas disposal. The gas is withdrawn into annular space to eliminate gas slug generation, ensuring Alnas ESP unit steady operation and enhancing mean-time-between-failures.
Dispenser is designed for refining entrapped gas in formation fluid, preparation of homogeneous gas-liquid mixture and feeding it to submersible centrifugal pump inlet. When gas-liquid mixture flow passes through dispenser, its homogeneity and entrapped gas breakage degree rise, enhancing centrifugal pump operation: lower vibration and stream pulsation in tubing, providing operation with efficiency required.
Gas separator-dispensers are installed at pump inlet in lieu of gas separator/ dispenser in ultrahigh GOR wells, where separator or dispenser application cannot ensure electrical centrifugal pump steady operation.
APPLICATION CONDITIONS GSAIS54M1 gas Gas separators, dispensers, and gas separator-dispensers (the "products") are designed for separator applications with formation fluid parameters as follows.

DOUBLE-STAGE (DIFFERENTIAL) PUMP 30-225/150 RHBM 12-4-2-2
Consists of: Operation scheme of a double-stage pump • Barrel with standing valve. There is a hollow rod guide on the top of barrel for sealing upper chamber (high-pressure stage)
• Plunger with traveling valve and hollow polished rod with additional valve on the top of a rod. Rod is connected with plunger with the help of adapter with side holes connecting internal hollow of a plunger and a rod with upper cham- Additional valve ber which is the space between rod and barrel Hollow rod sealing • Inner hollows of a plunger with traveling valve, rod with valve and upper cham- ber create high pressure stage. Under-plunger space (lower chamber) is a low pressure stage. Hollow polished rod
Pump operation: Barrel When plunger moves upwards, both plunger valves are closed; standing valve is opened, and well fluid flows in a lower chamber (low pressure stage)
When plunger moves downwards, upper plunger valve remains closed and standing valve is closing. Fluid flows in upper chamber through open lower plunger valve Plunger With following upstroke, lower plunger valve is closed by fluid pressure, which is achieved by diminishing upper chamber space Traveling When pressure in upper chamber equals the fluid column pressure in tubing string, valve upper plunger valve opens and fluid flows in tubing string. At the same time, fluid flows through opened standing valve into lower chamber
Thus, lower chamber is filled and released without fluid column pressure in tubing. It creates favorable conditions for pumping gassed well fluid. Standing valve

TUBING PUMPS OF SPECIAL DESIGN
Pumps ТНМ-Т with diameters 32, 44, 57 and 70 mm with non-removable standing Pump with non-removable valve. standing valve of THM-T type
Standing valve is set in the bottom of pump instead of seating nipple; fishing tool is not available. Diameter of standing valve (seat and ball) for pumps with diameters 32,44,57 mm is oversized, providing more stable pump operation (free of valve sticking, oc- curred because of paraffin deposits). Pumps are used together with drain valve (SKOK type or other) placed above pump to drain fluid from tubing when pump is pulled out.
The following makes are developed on the base of THM-T pumps:
• pumps with non-removable standing valve, barrel with side drain hole and long plunger (10 feet) (ТHМ – Т 11-10-2-2). Plunger is fitted so that side hole of barrel is constantly covered by plunger; plunger stroke is 3 m. When plunger is in its lower position (at its stop) and when it is pulled out from barrel, drain hole is opened to ensure drain of fluid from tubing both when plunger is pulled out on rods and when rods and plunger components are parted or unscrewed; direct flushing at well completion is provided as well.
• pumps with side standing valve (BVK). Plunger The plant produces BVK valves for THM-T tubing pumps with diameters of 32 and 44 mm. BVK valve is delivered optionally and set under barrel instead of bottom part of a pump. In pumps equipped with BVK valves dead space is almost zero in a barrel, when a plunger is in its lower position. This allows to operate wells with insignificant pump working submergence without risk of failure of fluid feed due to pump blocking by gas.
• pumps with non-removable single (THM-C) or doubled (THM-CC) standing valve Traveling and built-in drain beating device. valve Diameter of standing valve (seat and ball) in pumps of diameters 32, 44, 57 mm is Non -removable standing valve oversized. Fishing tool is not available. Fluid is drained from tubing through a hole in beating screw which is broken with beating tool thrown into well.

69 ABOUT IZHNEFTEMASH Equipment for well cementing
SEALING INSERT
The sealing insert has the central channel for the cable of the geophysical instrument. The cable is sealed with rubber rings.
BLIND INSERT
The blind insert overlaps the central channel of the pump and lets the fluid flow from the tubing to the injectors through the side channels. When the working fluid comes out of the nozzle, the underpressure zone is formed in the mixing tank, where the bed fluid enters and comes off in the hole clearance through the diffuser. The reduction of the bottomhole pressure is checked by the gage, installed on the insert.
ACID PREVENTION INSERT
The central channel of the insert is closed by the valve with the spring-loaded ball. Under the impact of the fluid pressure in the tubing the valve opens and allows the acid solution to penetrate into the bot- tomhole formation zone with shutting off the fluid flow in the side channels.
FISHING TOOLS
Fishing spears and sucker rod sockets for external gripping, of collet type, non-releasing are intend- ed for gripping and pulling out the tubing, bottom-hole pumps, downhole motors and sucker rods during elimination of downhole failures.
