Abstract
The invention relates to a cross-linking agent able to crosslink hydrophobic modified hydroxypropyl guar and a preparation method thereof. Presently at home and abroad, water-based fracturing liquids are more likely to be employed in fracturing of most reservoirs, and the practice has the following disadvantages that: (1) a fracturing liquid system with routine guar gum as the densifier is only suitable for intermediate and low temperature stratums, so that a limitation exists for high temperature wells with a temperature over 150DEG C; (2) generally, fracturing liquids needs more additives, thus causing damage to stratums to a certain degree. The cross-linking agent of the invention comprises by weight: 150-200 parts of water, 140-160 parts of glycol, 60-70 parts of boric acid, 60-80 parts of zirconium oxychloride, 180-200 parts of acetic acid, 20-240 parts of monoethanolamine, and 50-180 parts of sodium hydroxide. In an enclosed container, the final product can be produced. The cross-linking agent of the invention can form a fracturing liquid with a densifier, and the formed fracturing liquid can resist a temperature higher than 150DEG C. The cross-linking agent and the densifier fracturing liquid system in the invention have the characteristic of low interfacial tension.
