| titleOfInvention | Elastic sand-carrying fracturing fluid, thickening agent for fracturing fluid and preparation method of thickening agent |
| abstract | The invention belongs to the technical field of oilfield chemistry and fracturing yield increase, and provides an elastic sand-carrying fracturing fluid, a thickening agent used for the fracturing fluid and a preparation method of the thickening agent, wherein the thickening agent comprises the following components in parts by weight: 0.5-1.5 parts of acrylamide; 1-5 parts of octadecyl trimethyl ammonium bromide; 0.05-0.15 part of potassium persulfate; 0.005-0.015 part of alkali; 1-5 parts of diethylene glycol distearate; 0.5-1.5 parts of triglycerol diisostearate; 0.2-0.8 part of sodium tetradecyl carboxylate; 0.2-1.5 parts of fatty acid amide propyl dimethylamine; 0.2-0.8 part of tertiary amine alcohol; the elastic sand-carrying fracturing fluid consists of the following components in percentage by weight: 0.20 to 0.55 percent of thickening agent; 0.20 to 0.55 percent of cross-linking agent; 0.1 to 0.5 percent of cleanup additive; 0.1 to 0.5 percent of anti-swelling agent; the balance of water; the preparation method comprises the steps of preparing an acrylamide solution, an intermediate solution, a product and a thickening agent. The elastic sand-carrying fracturing fluid is simple in fluid preparation, obvious in construction effect and good in rheological property; after the thickening agent and the cross-linking agent are used together, the viscosity is low, and the sand carrying capacity is strong. |
