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 ...

Abstract

The invention relates to a thickening and tackifying agent for a fracturing fluid. The thickening and tackifying agent comprises 30 wt% of white oil, 50 wt% of an acrylamide monomer, 3 wt% of ethanol,1.5 wt% of sorbitan fatty acid ester, 0.5 wt% of hexadecyl trimethyl ammonium bromide, 0.5 wt% of a suspension stabilizer and 14.5 wt% of water, wherein the suspension stabilizer is prepared from Arabic gum and acrylic acid-sodium p-styrenesulfonate-hydroxyethyl methacrylate. The thickening and tackifying agent disclosed by the invention has the advantages of excellent suspension stability, smallrequired preparation space, low requirement on water quality, good tackifying effect, good sand suspending effect, long retention time, good shearing resistance, good high-temperature resistance, good salt resistance, wide application range, good compatibility, low construction cost, small influence on environment and wide application prospect.

Description

technical field [0001] The invention relates to a thickening viscosifier for fracturing fluid, in particular to a thickened viscosifier mainly used in oilfield fracturing construction technology as the preparation of a low-cost fracturing fluid system. Background technique [0002] Thickening viscosifier is a kind of polymer additive used to increase the viscosity of aqueous system and improve rheology. Adding a little thickening tackifier to the system that needs to be thickened can significantly increase the apparent viscosity of the system to meet the requirements. It is widely used in oil drilling, food industry, agriculture, daily chemical industry, pharmaceutical industry, textile printing and dyeing and other fields. At present, the most widely used synthetic thickened tackifiers are alkali-soluble polyacrylic thickened tackifiers. The molecular chain of this kind of thickening thickener contains a certain amount of carboxyl groups. When it is neutralized with alkal...
