Emulsifiers Technology
  • Oil enhancement process and product specifically developed for heavy-oil steam huff-and-puff, for improving efficiency
  • Greatly reduce the viscosity of the viscous crude oil lifting and may achieve rate 95-99% at 350°C temperature resistance
  • Flow catalyst during the viscous oil conveying, to reduce the conveying pressure, improving efficiency and cost-savings
Item Description Index
Appearance Brown liquid
Solubility Soluble in water
pH Value (at 1% aqueous solution) 7 ∼ 9
Condensation point -10°C
Viscosity reduction rate (at 50°C) ≥ 95-99% (varies from initial viscosity of viscous oil)
Temperature resistance, °C ≥ 350
Free-setting dehydration rate ≥ 80%
  • Interfacial tension between the oil-and-water in most of oilfields below 10-3mN/m, to sufficiently improve the displacement efficiency
  • The application of binary oil-displacing system composed of polymer (polyacrylamide) shows it will enhance the oil recovery by 12-22%, as compared with water flooding
  • Applicable to the condition when chemical displacement of reservoir oil is carried out for improving, and to other conditions when the tension of interface between oil and water needs to reach the extremely low level

  • The combination method of blocking, adjusting and driving is applied to improve the overall efficiency of the steam huff-and-puff block
  • Using heat provided by steam stimulation to improve the fluidity of viscous oil, and injecting hot liquid to improve oil-scavenging efficiency work
  • Chemical agent with remarkable high-temperature resistance characteristics, to increase temperature of stratum with steam stimulation, to ease the residual oil flow during production
  • This can be applied to the management of severe non-homogenous reservoir caused by long-term steam stimulation and declined in throughput efficiency crude oil well
  • This technology overcomes the shortcomings of conventional oil-based wax removers and water-based anti-wax agents
  • Uses composite surfactant systems as emulsifiers, and develops anti-wax double-effect agents series – including compound antifreeze wax remover, micro-emulsion heavy wax crystal emulsifying dispersant; to effectively remove and disperse the wax crystal, reduce its disposition, lower operating load of pump, extend hot-wash cycle and increase production in different water-containing and wax-disposition stages of oil wells
  • Wax removal and anti-wax operations for oil wells with high wax content, assisting during the collection and transportation of crude oil

  • Optimally cultivated bacteria (microorganism) for heavy oil reservoir and high-waxy oil reservoir
  • In the course of biological metabolism, paraffin, colloid and bitumen and other heavy components are used as nutrients and thus these substances in crude oil are deemed as food of microorganism and decomposed to generate light-component hydrocarbon, thus reducing viscosity and freezing point of crude oil and enhancing its mobility
  • In metabolic process, the microorganism will generate biosurfactant, organic acid and alcohol, ester and other organic solvent substances, which can be used to reduce oil-water interfacial tension; alcohol and organic ester and other organic solvents may alter surface property of rock and physical property of crude oil, release crude oil which is attached to rock surface in the gap, thus smoothening oil leakage channel and increasing production of crude oil
  • Its operating application via:
    • To inject microorganism in process of oil recovery for single-well gas injection
    • Directly inject microorganism into water injection well to remove oil layer by injected water

Appearance Light pink or brown
Total number of bacteria is no less than 108∕mL
Interfacial tension (mN/m) is no more than 9.99×10-2
  • The skin-effect principle is applied, whereby oil tube is heated by forming circuit with casing pipe
  • Alternating current generates skin-effect-current on ferromagnetic steel tube, the oil tube will generate heat and heat the crude oil in shaft and thus heats viscous oil, reduces viscosity, removes the blocking and controls paraffin with high-solidification point oil
  • The technology is characterized by simple equipment structure, flexible control, rapid heating, high heating efficiency, long service life, wide application range of oils and wide range of working conditions (with and without poles) and low equipment and production cost, etc
  • Moreover, it has characteristics of rapid temperature control, uniform heating along the stroke, easy processing of fuse tubes during power failure, high heating efficiency and automatic control
  • Heating depth: depends on down-hole conditions, above 4,000m in general
  • Heating temperature: can be adjusted according to freezing point under the shaft and actual demands in wax-bearing conditions
  • Operating convenience: it is convenient to lift and lay down in process of operation without increasing workload of operating crew
  • Management convenience: workers on site can adjust heating efficiency at any time, easy to operate
