Embodiment 1
[0025] A fracturing fluid viscosifier, comprising 30wt% white oil, 50wt% acrylamide monomer, 3wt% ethanol, 1.5wt% sorbitan fatty acid ester, 0.5wt% cetyltrimethyl Ammonium bromide, 0.5 wt% suspension stabilizer and 14.5 wt% water.
[0026] Wherein, the suspension stabilizer is composed of gum arabic and acrylic acid-sodium styrene sulfonate-hydroxyethyl methacrylate in a mass ratio of 2:1.
[0027] The preparation method of the viscosifying agent for fracturing fluid comprises the following steps:
[0028] Step 1: Pour white oil into the container, add acrylamide monomer, ethanol, sorbitan fatty acid ester under stirring;
[0029] Step 2: Pour distilled water into the container, add cetyltrimethylammonium bromide under stirring state, add suspension stabilizer after fully dissolved;
[0030] Step 3: Slowly add the solution obtained in step 2 to the solution obtained in step 1 to obtain the thickened viscosifier for fracturing fluid.
[0031] 170s-viscosity measured at room ...
