DY-011
Dayong
Product description
The product is composed of anionic surfactants, nonionic surfactants and co-solvents, which has good black resistance and is compatible with medium such as formation water and acid. This product is composed of several surfactants, stabilizers, etc. It has a certain ability to wash oil stains, which can greatly reduce the interfacial tension such as surface tension, high foam viscosity and have strong stability.
Performance index：
Description | Index |
Appearance | Light Yellow liquid |
ph | ≥9 |
Content of effective substance | ≥30% |
Foaming ability | ≥180ml |
Half-life period of foam | ≥30min |
Thermal degradation rate | ≤15% |
Main function
It is Mainly used in thermal oil recovery to improve crude oil production and recovery efficency. Temperature resistance can be up to 300 °C . it can be used for pressure, leakage, water sensitive formation sand washing, lure spraying, well washing and assisting, deep hollowing, bottom hole purification and other operations. It can be used for foam flooding to improve oil recovery and other types of active oil flooding, such as active water flooding and microemulsion flooding. It can be used as a drainage aid in acid fracturing operations.
Instructions for use
The foaming agent is formulated into a 2% aqueous solution on the ground, which is alternately injected into the formation with the gas, or simultaneously injected into the formation. the foaming agent solution is injected from the casing, the gas is injected from the oil pipe, and the foaming can also be carried out by immersion in the foaming to foam and then injected . The nitrogen generator is combined with the gas injection equipment to inject the foaming agent into the formation, and the injection amount per well is about 3-5 tons.
