RockySea Oilfield Steam Boiler


  • Supercritical Oilfield Steam Injection Boiler
  • Desulfurization and Denitrification Oilfield Steam Boiler
  • Produced-water Oilfield Steam Generator
  • Superheated Oilfield Steam Boiler
  • High-dryness Steam Injection Boiler
The Oilfield Steam Boiler is a Once Through Steam Generators with a forced circulation rate of 1. The pressure of medium flow is generated from the plunger pump. This steam injection boiler is mainly used for heavy oil recovery and extra-heavy oil recovery. Oilfield steam generator can be used for heavy oil CSS and steam drive. Steam injection for oil recovery is to inject saturated steam into the oil layer to heat the oil layer, so as to reduce the viscosity of heavy oil, make it easy to flow, and promote the heavy oil flow to oil wells. RockySea Petro has rich experience in oil field steam injection boiler manufacturing and can produce various types of high quality boilers.


Description 

RockySea Petro 1986, the RockySea Petro Petro’s former has obtained the qualification for manufacturing Class I and II pressure vessels. Now the SANJACK ‘s special equipment has the national A2 level (Ⅰ, Ⅱ, Ⅲ) pressure vessel manufacturing qualification; D-level pressure vessel design qualification; A-level boiler manufacturing, installation, alteration, repair & maintenance qualification.

The main products under pressure include various pressure vessels for the oilfield and chemical industry:

1）Steam injection boiler supporting compensator, manifolds, etc.
2）Water treatment for steam injection boilers;
3）Oilfield steam injection boiler (OTSG);

Basic information of OTSG

Oilfield steam injection boiler, also known as wet steam generator, is a special steam injection equipment for heavy oil exploitation in oilfields. It uses the heat generated by the combustion of gas or oil to heat water and vaporizes it, so that high temperature and high-pressure wet steam is injected into the oil well, and the crude oil in the oil layer is heated to reduce the viscosity of the heavy oil, thereby increasing the fluidity of the heavy oil, which can greatly improve the recovery of heavy oil.







1.Basic Structure

Oilfield Steam Boiler mainly consists of the combustion system, water procedure and power systems and control systems. RockySea Petro oilfield steam boiler adopts direct current and forced circulation mode, without pot and has the characteristics of compact structure, light weight, high automation and quick start and stop.

3.Accessory Equipment

In order to ensure the efficient operation of the team injection boiler in oil field, the boiler has a large number of accessory equipment. RockySea Petro’s oilfield steam generator accessory equipment adopts integrated and modular design, which can perfectly match the boiler and give full play to the boiler’s maximum energy efficiency.




4.Basic Technical Parameters:

  • Loading method: mobile vehicle; fixed skid
  • Control mode: PLC + touch screen + industrial computer, and can realize manual operation, need to set the compound automation remote transmission interface standard.
  • Rated dryness or superheat: 80%, 85%, 90%, superheat 5-23℃
  • Load change rate: When the load changes from 50% to 100%, the boiler operates normally and safely, and can realize the simultaneous tracking of water and fire.
  • The total pressure drop of the boiler: ≤4.0 MPa (under rated conditions)
  • Fuel used: crude oil/natural gas
  • Design thermal efficiency: fuel oil: ≥91%; fuel gas: ≥92%
  • Rated working pressure: 17.2, 21, 26MPa
  • Rated evaporation: 9.2, 11.5, 15, 18, 23, 30t/h

5.Advantage

  • Unattended Operation
    A mathematical model is set up on the basis of heat balance, automatically adjusting fire and quantity and guaranteeing constant dryness, so as to realize unattended operation.
  • Environment Protection
    High dryness section can reduce exhausting gas temperature to meet the national environment protection requirement
  • High Heat Efficiency
    Applied dryness and flue gas oxygen control technology can guarantee the heat efficiency stable operation, the heat efficiency can reach more than 90%.
  • Anti-Scaling
    High dryness steam heat absorption is conducted in convection section and there will be no scaling It has good heat transfer effect and is safe to operate.
  • High Dryness
    The dryness of steam can reach 100% after adding the steam-water separator during process.
In just a few years, ANJACK’s oilfield steam injection boiler quickly occupied shengli oilfield, China, market and quickly spread in China’s major oilfields. Oilfield steam injection boiler has the following advantages.
