Product Overview

Clean proppant-carrying fracturing fluid is a new type of surfactant-based polymer-free fracturing fluid. It features low frictional resistance, low fluid loss, good shear resistance, high proppant transport capacity, high proppant concentration capability, excellent break performance, fast flowback rate, low formation damage, and simple on-site operation. It consists of specialty surfactants, a specific concentration of salt solution, and activators. The fluid is thickened by forming wormlike micelles that entangle into a network structure, achieving crosslinking. When the fluid comes into contact with organic matter or other lipophilic substances, the wormlike micelles break down into small spherical micelles, the network structure is destroyed, and the solution viscosity decreases, achieving the goal of breaking the fracturing fluid.

Physical and Chemical Properties:

Component A(B)

• Appearance:Light yellow liquid(Brownish liquid)
• pH value:8–9(5-7)
• Density (25°C), g/cm³:≥ 0.9(1.0)
• Gelation performance of clean fracturing fluid – Viscosity (30°C, 170 s⁻¹), mPa·s:≥ 100

Usage Method and Precautions:

The clean proppant-carrying fracturing fluid consists of two components, A and B, with a recommended mixing ratio of 2:1 by volume. The fracturing fluid can be prepared on site prior to the job, or Components A and B can be metered directly into the brine solution in the blender during pumping; the fracturing fluid then forms directly within the pipe string.
During preparation, the brine can be2–3% KCl or NH₄Cl solution, or 1.5–2.0% polyquaternary ammonium clay stabilizer solution. The concentration of Component A is generally 1.5–7%, and Component B is generally 0.75–3.5%. The concentration selection depends on the expected formation temperature: the higher the temperature, the higher the concentration required.
