Assisting agent

For some areas where the formation contains heavy oil, wax oil, asphaltene, and colloidal oil , when deep oil layer is exploited ,the method of heavy oil cold mining should be considered . Chemical and puffing are applied to the formation, and chemical agent is used in the wellbore to reduce viscosity . According to the molecular structure of asphaltene and colloidal , the main components of heavy oil, , a new type of heavy oil viscosity reducer is synthesized through reasonable molecule design . Its special molecular structure makes it have strong affinity with large polycyclic aromatic hydrocarbons ,and it has better hydrophilicity. Therefore, the overall performance is better dispersibility, emulsifying property and wettability to heavy oil. After a large number of indoor performance evaluations, the product can be used in low temperature formations, and its viscosity reduction rate can reach 80-90%. The assisted recovery rate can reach over 95% under normal temperature conditions.

Instructions for use：

The product is put into contaminated water at 0.5-1.5% in use, mixed up with water. Viscosity reducer hydrosolvent fluid at oil-water volume ratio of 70:30 is injected into stratum. After circulation, it becomes emulsion with oil in water and at flow dispersed state.
