Description
Surfactant SY*1 oil-displacing agent
Nature： Â
Appearance: light yellow or yellow brown liquid
PH value: **8Â Â
Effective content: *0%Â Â
Surface tension:（0.**0.3%aqueous solution
mN/m）≦*0 Â
Oil and water surface tension:（0.**0.3%aqueous solution
mN/m）***2 ~***3
Function features：
1. High temperature resisting, salinity resisiting low pollution,
low damage, easy to operate, flooding, strong function and other
characteristics.
2. Reduce the oil / water interfacial tension, effectively reduce
the oil / water interfacial tension between ***2 to ***3 mN / m,
the ultra-low state, thereby greatly reducing or eliminating the
formation capillary action, reducing the stripping of crude oil
needed to stick attached to the power, to improve the efficiency of
the wash oil.
3. Closely related to the oil displacement efficiency and rock wet
ability change the wet ability of rock surface. Oil-wet surface to
lead to poor efficiency of the flooding, wet surface allows the oil
displacement efficiency. This product can greatly increase the
wetting angle between crude oil and rock wet ability of the rock
surface can become strongly hydrophilic and wetting reversal does
not occur, is extremely beneficial to water flooding.
4. Emulsification. This product has strong emulsifying ability in
the water-oil two-phase flow dynamic shear conditions. The rock
surface adhesion of crude oil dispersion, stripping, and the
formation of oil in water (O/W) emulsion, and effectively improve
the oil-water two-phase mobility ratio and improve the drive for
the sweep efficiency of the solution, so as to achieve the purpose
of enhancing oil recovery.
Main feature:
1. Injected with water
2. Can greatly improve the efficiency of wash oil, is a low-input,
high output additives
3. Suitable for all oilfield polymers flooding, suitable polymer
should not be injected into a small fault block oil field.
4. Oil field recovery can be increased by *0% to *5%. 5. Not ground
manifold and equipment corrosion
6. Produced fluid non-toxic, no pollution to environment. (Finished
more than *8%)
Product introduction：
  SY*1 the high-performance displacing agent is
developed for the improvement of secondary recovery and EOR
recovery special surfactants, efficient and convenient way. Has
excellent the applicability of Permeability, low pressure,
low-yielding, high-wax oil field. Extend the oilfield period; the
effect of flooding is significant. Our company\'s current annual
output is tens of thousands of tons.
Mechanism of oil belt formation：
In the role of the goods, more and more oil droplets wash out from
the rock table, move the process forward, colliding with each
other, gathered merged into the oil belt; oil belt and more oil
beads convergence, gather into a piece of oil column or oil walls.
With the continued displacement process, the oil column or oil wall
will flow to the well so as to achieve the purpose of enhanced oil
recovery.
Usage and dosage:
Single well: 0.3~0.5% of the product solution with water,
intermittent injection, the effectiveness of cycle: 3~4 month.
Injection wells Group: continuous injection of 0.1 to 0.3% of the
product solution with water, the effectiveness of cycle: 7~*0 month
(**0 to **0 days)
