Technology Description：
Heavy oil is a kind of crude oil which contains features such as high density, high viscosity and poor fluidity. The content of asphaltene and colloid is high, so the conventional oil extraction technology is difficult to extract.
The nano compound type super heavy oil assist producing medicament, which is researched and manufactured by our company, belongs to water fluid emulsion viscosity reduction assist producing medicament. It is composed of the ion and anionic type surfactant and nano inorganic additives. When the product is in contact with the heavy oil, it can make the oil-water interface tension decrease, and form the O / W type emulsion liquid. The surfactant molecules are absorbed around the oil droplets to form a protective film, preventing the re-aggregation of the oil droplets. Nano inorganic additives, by means of entering the oil-water interface, surrounded by asphaltenes, the asphaltenes can make nano inorganic additive particles wet, and form the rigid membrane around the water to prevent water droplets from aggregating, reduce the frequency of collisions and the coalescence rate between the droplets, and improve the emulsion liquid’s stability. Reduce the friction force between the emulsion liquid and the tube wall, as well as the internal molecular of the emulsion liquid, in order to achieve the purpose of the heavy oil viscosity reduction, increasing production.

5. The company’s product technology can be used under the circumstance of the homoiothermy.
6. The demulsification separation time can be adjusted according to the customer’s requirements.
7. After the use of the product, it does not affect the crude oil’s quality.
The main characteristics of the product and the difference & advantages with the present market similar products
a. The compatibility between the product and oilfields’ oil-water is very good.
According to the requirements of the different viscosity of heavy oil, crude oil components，the water salinity, and the water divide time, the product can carry on composing appropriately towards the host agent and the addition agent in order to meet different needs, and achieve the best viscosity reduction and increasing production effects.
b. The temperature adaptation range is wide.
The product’s temperature adaptation range is 40-350 ℃, and meet the heavy oil recovery of the high temperature environment.
c. The adding amount is small, whereas the viscosity reduction effect is good.
The product’s adding amount is small. The viscosity reduction and the production increasing effect are good. What’s more, it provides high quality and reasonable price. Under the adding amount of 0.4%～1.2% (Measure by the producing fluid volume), the viscosity reduction rate can reach 99%.
d. The use of the product is very simple.
According to the producing fluid as the calculation basis, use a certain amount of water to dilute the product, and through the tubing-casing annular space, carry on the quantitative injection. In the process of lifting, can form the O / W emulsion system with the heavy oil, and make viscosity reduce significantly.
e. The product belongs to environmental protection product, non-polluting, and can’t cause pollution and damage to the environment, oil recovery equipment. The use process is safe and environmental protecting. This product is water-based, with no explosion prevention requirement. It has no effect on the post-processing of the crude oil, and no need to add the demulsifier. The oil-water can separate, and it’s very easy to use.
