| titleOfInvention | A kind of fracture acidizing low frictional resistance emulsification acid solution and application thereof |
| abstract | The present invention relates to the low frictional resistance emulsification acid solution of a kind of fracture acidizing; In this emulsification acid solution oil phase and acid mutually by volume summation 100 parts count, than being 30:70; Oil phase forms by volume summation 100 parts and counts: 0.25 ~ 0.5 part of ODEA, 0.1 ~ 0.3 part of octadecyl primary amine, 0.2 ~ 0.6 part of n-caprylic acid, 1 ~ 3 portion of friction reducer, and remaining is diesel oil; Acid phase composite by volume summation 100 parts count: 1 ~ 3 portion of acid solution multipurpose additive, 1 ~ 2 portion of cleanup additive, more than be 28% concentrated hydrochloric acid; This emulsified acid wraps sour milk sap for stable oil at normal temperatures, has higher viscosity, lower frictional resistance, higher slow ability and the good row's of helping ability, expands acid fracturing treatment radius for realizing, improves acid corrosion fracture. |
