Electric submersible pump system
Electric Submersible Pump System
Since the invention of the electric submersible pump in the 1930 s, it has been widely used in the artificial lift oil production system of offshore oil fields and onshore oil fields because of its compact structure, convenient use and simple operation.
TVM series standard submersible motor products. This series of products is interchangeable with REDA products in terms of connection dimensions. This series of products adopts materials such as thrust bearings and high strength alloy shafts. The products are featured by high performance indicators, reliable operation, and a complete range of product varieties. TVM series products are applicable for well temperatures of 120 ℃ and 150 ℃, with an insulation temperature rating of 180 ℃.
The TVEM standard modular protector can have 2 - 6 chambers to implement different combinations in structure and meet different well conditions and customer needs.
The TVEM rotary separator is a device that effectively separates the gas-liquid mixture it inhales based on the principle of different centrifugal forces generated by substances of different densities under high-speed rotation. When the gas content at the pump intake is lower than 30%, a single tandem separator can be used to reduce the gas content to the allowable range of the pump; When the gas content at the pump intake is slightly higher than 30%, a series of connected oil and gas separators can be used to ensure the stable and reliable operation of the submersible pump.
The TVEM submersible pump is a multi-stage centrifugal pump, which is an efficient and energy-saving submersible product.
The new high-efficiency gas processor of TVEM adopts a new design concept, with an axial flow structure internally. High pressure is generated through the internal worm gear, which compresses the gas entering the processor, reduces the gas volume, forms uniformly distributed small bubbles or disappears, thereby transforming the well fluid entering the suction port of the centrifugal pump from the original gas-liquid two-phase mixture into a single-phase liquid or a uniform mixture containing a small amount of gas, preventing the unit from being affected by gas lock, cavitation, and other factors.
● Tungsten carbide radial bearing
● Ni-resist inducer and impeller, investment casting

One end of the MLE connects with the submersible motor. The other end connects with the power cable. It will provide electricity to the submersible motor. It has excellent sealing property and electrical property. In terms of the insulating material of connecting cable, the product is divided into different temperature and voltage ratings. According to the armor material, is can be divided into general type and anti-corrosive type. It can also be divided into plug-in type and tape-in type according to the installations mode.
TVEM power cable has round and flat type in terms of its profile. They are used for supplying electric power to ESP units rated at 3kV or 6kV. The size of the cable conductor ranges from AWG# 7 to AWG# 1. TVEM power cable maintains a brilliant performance under high temperature, oily and corrosive environment. Different options are available upon user’s request.
