| titleOfInvention | A kind of double slug Compositional type profile control agents of positive rhythm reservoir and its application method |
| abstract | A kind of double slug Compositional type profile control agents of positive rhythm reservoir and its application method, are related to field use chemical field.The present invention is injected in positive rhythm reservoir by double slug forms, and preposed attributives form the polymer with matrix type cross-linked structure by mixing different molecular mass fraction hydrolyzed polyacrylamide and additive, compounding, can implement firm closure to oil reservoir bottom high permeability area；Rearmounted slug is compound surfactant, injects oil reservoir after preposed attributives effectively block, and surfactant flooding is carried out to the hypotonic band in oil reservoir high-order bit, to reduce residual oil content in oil reservoir, increase oil reservoir injectivity index；Improve Reservoir Heterogeneity by way of double slug combinations, increase sequent water flooding sweep efficiency, suppress positive rhythm reservoir region of bypassed oil and formed, to improve the drawbacks such as traditional oil production method, deficiency in economic performance low to positive rhythm oil recovery. |
