Hi-Temperature Foaming Agent

The agent consists of anionic surfactant, non-anionic surfactant and co-solvent. It has good temperature withstand performance and is suitable for use with the medium like stratum water and acid liquid. It consists of surfactants and stabilizer and is capable of removing oil stain. It significantly reduces interface tension like surface tension with high foaming viscosity and strong stability.

Technical Index:

Prodcut Function:

The agent is mainly used for thermal oil extraction to improve crude oil output and recovery rate. Withstanding 300°C, the agent may be used for sand flushing, induced spray, well flushing and drainage aid, deep tunneling and well bottom cleaning in low pressure, leaking or water sensitive stratum. When used for foam displacement of reservoir oil, the agent helps to improve oil recovery rate. It can also be used in active agent oil displacement of other types, e.g., active water displacement and micro-emulsion flooding. It is used as drainage aid in acidifying fracture operation.

On-Site Application :

The foaming agent is diluted on ground into 2% water solution which is injected into stratum alternately with air. The solution and air may also be injected together. Foaming agent solution is injected through the casing tube and air through oil pipe. The foamer dip in the solution is used for foaming which is then injected to the ground. Nitrogen making vehicle is used together with the injection equipment to put the foaming agent into stratum. The amount of the agent injected into each well is around three to five tons.
