Добыча нефти и газа - NETZSCH Насосы и Системы

Добыча нефти и газа

«Нефть и газ во всем мире считаются важнейшими источниками энергии. Несмотря на то, что открываются новые месторождения, транспортирование этого сырья постоянно усложняется и требует непрерывного совершенствования технологий. С помощью эксцентро-шнековых систем NETZSCH можно эффективно транспортировать и использовать большую часть этих запасов. Это требует очень тесного сотрудничества со специалистами нефте- и газодобывающих фирм уже на этапе разработки месторождений и постоянного улучшения насосов, приводов и систем нашими инженерами и техниками. Сложные геологические условия, добыча в море и глубины установки более 2 500 м постоянно ставят перед нами новые вызовы. Благодаря сооружению центров NETZSCH-Pump в важнейших регионах добычи нефти и газа мы по всему миру создаем замечательные условия обслуживания для наших партнеров. Одновременно продукты NETZSCH завоевывают новые области применения, как, например, отвод воды газовых буровых скважин и приповерхностная геотермия.»

Success Stories

NETZSCH Upstream conveys extremely difficult media to oil and gas fields

Despite all efforts to promote renewable energies, global demand for crude oil and natural gas has continued unabated. Methane from coal seams and highly viscous oil at more than 10,000 mPas are already of commercial interest, but are just as complicated to extract. In the Qinshui Basin in China the extraction is as difficult as the extraction of oil sand mixtures from the Sudanese desert where temperatures up to 50°C can be reached. More

Special Pumps & Systems

NETZSCH Insertable Progressing Cavity Pumps

The main feature of Progressing Cavity Pumps (rotor & stator) is their assembly inside the tubing. Thus, the pump is not connected to the production line but assembled inside it.

Applications

  • Wells with low flow – the cost of the intervention makes the use of a normal pump economically not suitable
  • Wells with a high frequency of interventions (independent of the flow)
  • Flow range 1,3 to 491 bpd at 100 rpm
  • Pressure range 100 to 240 bar
  • Pump with downhole sensors


Advantages

  • Minimization of the time of intervention
  • Minimization of costs of rig
  • Minimize rig’s costs in workover services, this minimizes production losses
  • Pump substitution without removing it from the tubing
  • Pump substitution with flushby equipment
  • Up to 60 % savings in pump replacement
  • Does not require removal of downhole sensors and cable

NTU Progressing Cavity Pumps

Produced with steel tube conform with the same internal geometry as the stator (helical). Thus the elastomer has a uniform wall and produces even distribution of the elastomer. The main NTU pump feature is its lower operation and starting torque due to its lower swelling when exposed to temperature variations and chemically aggressive fluids.

Advantages

  • Short pump length
  • Lower starting and operational torque
  • Longer run life under severe fluid conditions
  • Less influence due to temperature and chemicals
  • Easier to assemble in wells with deviations
  • Lower hysteresis
  • Better heat dissipation

 

 

NTM Progressing Cavity Pump

  • Maximum flexibility in the  perspective of viscosity andtemperature
  • No chemical attack on the elastomer
  • Perfectly suited in combination with thermal treatment of the wells

Advantages

  • Short pump length
  • Lower starting and operational torque
  • Longer run life under severe fluid conditions
  • Less influence due to temperature and chemicals
  • Easier to assemble in wells with deviations
  • Lower hysteresis
  • Better heat dissipation

Submersible PCP

NETZSCH Submersible Progressing Cavity Pump

Advantages of the NSPCP©

  • Designed for directional and horizontal wells
  • High efficiency – also with small production rates
  • No rod and no tubing wear
  • No gas lock associated with ESP
  • No environmental impact on the surface
