| titleOfInvention | A kind of compound acidizing and fracturing fluid and preparation method thereof |
| abstract | The present invention relates to a kind of compound acidizing and fracturing fluid and preparation method thereof.Fracturing liquid in the present invention adds multiviscosisty acid solution and additive on aqueous fracturing fluid base fluid and foamed fracturing fluid base fluid basis, and form through cross-linking agents.Wherein, aqueous fracturing fluid base fluid comprises carboxymethyl cellulose, chromium sulphate and polyacrylamide; Foamed fracturing fluid base fluid comprises urea and tensio-active agent; Additive comprises clay stabilizer, sterilant and cleanup additive; Multiviscosisty acid solution adopts concentration to be the hydrochloric acid of 12%, and the mixing solutions adding polyacrylamide and Rhizoma amorphophalli glucomannan is wherein to increase the viscosity of acidizing fluid, reduces the diffusing capacity of acidizing fluid to fracture plane, form colloid reticulated structure simultaneously, stop hydrogen ion movable, thus play retarded acting.In addition, the linking agent that this acidizing and fracturing fluid also comprises, surplus is water.This compound acidizing and fracturing fluid has the low feature of better high thermal resistance, endurance of cutting, injury. |
