COMPOUND FOR DISPLACEMENT OF OIL Russian patent published in 1998 - IPC

FIELD: oil production industry. SUBSTANCE: this relates to oil production stimulating compounds based on biological surface-active matters. This is aimed at improving efficiency of oil displacing compound due to higher intensification of oil emulsification combined with simplified preparation of compound. In function of biological surface-active matter, compound has cultural liquid of strain Pseudomonal acruginosa S-7 at degree of micellar solution with water of up to 100 times. Positive effect at watering is determined by inter-phase activity of displacing agent at boundary with oil and rock ground and also by emulsifying activity of agent with respect to oil. Biological surfacer-active matters in comparison with synthetic substances possess principle advantage - they are biologically decomposable, and this means that biological surface-active matters are ecologically clean. EFFECT: higher efficiency. 2 tbl, 7 dwg
