| titleOfInvention | A kind of double slug compounding profile control agents of hypotonic duct type oil reservoir and its application method |
| abstract | A kind of double slug compounding profile control agents of hypotonic duct type oil reservoir and its application method, are related to field use chemical field.The present invention is injected in hypotonic duct type oil reservoir by double slug forms, preposed attributives mixing sodium metasilicate, partially hydrolyzed polyacrylamide (PHPA), calgon, sodium sulfite, salicylic acid, aluminium citrate, with low viscosity, the characteristic that mobility is strong, anti-shear ability is strong, the hypertonic duct in oil reservoir inside can be implemented to blockļ¼Rearmounted slug is compound surfactant, implements surfactant flooding to the duct without closure, to reduce residual oil content in oil reservoir, increase oil reservoir injectivity index, improves the phenomenon that wax, colloid, asphalitine deposit near wellbore zoneļ¼Improve Reservoir Heterogeneity by way of double slug combinations, increase sequent water flooding sweep efficiency, suppress hypotonic duct type oil reservoir region of bypassed oil and formed, to improve traditional oil production method to drawbacks such as the hypotonic low, deficiencies in economic performance of duct type oil recovery. |
