The invention belongs to the technical field of oil and gas field fracturing, and in particular relates to an integrated recyclable and mixable fracturing fluid and a construction method. The present invention is formed by mixing 0.08%-2.0% of thickening agent and the balance of water; the thickening agent is 2%-5% by mass of viscoelastic surfactant and part by mass of 95%-98% A mixture of hydrolyzed polyacrylamide. The present invention does not need pre-mixing liquid or continuous mixing vehicle, realizes direct mixing and continuous construction, and no residual liquid is left on site after the construction is completed; the present invention can be repeatedly prepared by using the on-site fracturing flowback fluid, which solves the problem of on-site flowback. The problem is that the liquid is difficult to handle; the present invention directly mixes for continuous construction, does not need a continuous mixing car, and does not need liquid dispensing, thereby reducing labor intensity and improving construction efficiency. |
