Performance and application:
1. EHSB-40 is a biodegradable betaine-type viscoelastic surfactant, which can be used in daily chemicals and oilfield additives. The critical micelle concentration (cmc) at room temperature is 1.6×10-4mol/L. When the concentration increases to a certain concentration, the micellar structure will change, from spherical to rod-shaped gradually, and the solution can form a viscoelastic structure with a three-dimensional network structure.
2. EHSB-40 has a remarkable ability to reduce the interfacial tension of oil and water. The interfacial tension can reach 10-2mN/m or even 10-3mN/m under the conditions of surfactant concentration range of 0.06wt%~0.15wt%, salinity less than 10000mg/L, and temperature lower than 80°C.
3. EHSB-40 has a good emulsifying effect on crude oil. When the concentration of this product is 0.06wt%, the emulsion formed can remain stable for more than 24 hours, and the formation adsorption loss is less than 1mg/g, which can meet the use requirements.
4. The results of EHSB-40 laboratory oil displacement test show that surfactant flooding after water slugging can increase oil recovery by more than 10%.
5. At a shear rate of 170s-1, the viscosity of EHSB-40 is still higher than 40mPa·s at 70°C; at a temperature of 80°C and sheared for 2 hours, its viscosity is still higher than 25mPa·s. This system has good shear resistance. Cutness.
6. The sand-carrying performance test of EHSB-40 shows that the system can achieve good sand-carrying effect when the sand ratio is 30% or even 40%.
7. The gel breaking performance test of EHSB-40 shows that the system can break gel in the presence of formation water or crude oil, and there is no residue after the system breaks gel.
Packing: 200KG plastic drum.
Storage: Airtight storage at room temperature with a shelf life of two years.
