SiO2 nano-powder decompression and augmented injection for low permeability oil field

SiO2 nano-powder decompression and augmented injection
1.Particle size: 10-30nm
2. Purity: 99.8%+
3. Surface modified
SiO2 nano-powder decompression and augmented injection for low permeability oil field
1. Product profile
This nano resistance injection increase agent is nano silicon polymer produced by corporate reaction of sodium silicate or silicon esters and nucleating agent, surface modified by coupling agent contains hydroxyl, carboxyl, amino groups and saturated carbon chain and perfluoro carbon chain hydrophobic groups.


2. Product

features

1) It can be soluble in water with accessory material, forming clear transparent liquid.
2) Emulsion breaking under a certain environment, and release hydrophobic nanoparticles, and firmly attached to the porous road surface, forming a super-hydrophobic films, making the rock surface with the hydrophilic properties by water erosion transfer into a hydrophobic surface, resulting in when the injected water flow resistance through the pores greatly reduced, the injected water can pass through smoothly.
3) Nano particles could cladding on the surface of clay, stopping the water, prevent expanding; meanwhile the surface active component has hydrophilic group and lipophilic group, which also can absorb on the rock surface, change the wetting, improve aqueous phase relative permeability.
4) Nano material surface has pinning group, so it is more stable, stronger, more washing resistance on the rock surface, don't cause sand drop off, thus avoid secondary pollution.
5) It is non-toxic, non-pollution, not harmful to tubular column and operator, environmental friendly.

3.Usage
A. Configuration solvent: Dispersing this product in the water solution containing accessory agent by the density of 0.175%-0.25%(W/V)under special temperature.
B. Water injection well is preprocessed with a series of process such as acid cleaning; make dirty and organic sediment on the surface of rock clean.
C. Inject the prepared solution to water well, closing the well for 48-72 hours, make sure the product can absorb the underground rock surface adequately
D. Then using the clear water as the displacement and high duty water injection, then normal injection water, in such way completing once decreasing pressure and increase injection treatment. The validity is 4-12 months.

4. Product physicochemical index

5. Notes
1) This product should be stored in dry, ventilated place, away from fire and other dangerous goods.
2) Use fresh water when allocating liquid.
3) Stir well

6. Application case
The resistance reduction and injection increase technology for Water based nano silicone polymer is a new nano silicone polymer injection increase technology, improved by based that diesel and other organic solvent & mixed benzene ect.mixed system as Super hydrophobic nano-materials carrying agent, it completely realizes using water as carrying fluid, make the operation safe and environmental friendly, has incomparable superiority.
Our company first implemented the on-site operation in China, since the product enters the market, we have made the operation for 7 wells, basically achieved the purpose of decreasing pressure and injection increase.
