Abstract

The invention provides an organic aluminum-zirconium-boron cross-linking agent, a preparation method of the organic aluminum-zirconium-boron cross-linking agent, and an acidic guar gum fracturing fluid, and belongs to the technical field of cross-linking agents. The invention provides a preparation method of an organic aluminum-zirconium-boron cross-linking agent. The method comprises the following steps: mixing water, aluminum sulfate and zirconyl chloride octahydrate to obtain a zirconium-aluminum solution; carrying out a coordination reaction on the zirconium-aluminum solution and triethanolamine to obtain a coordination product; and sequentially mixing the coordination product with tartaric acid, an acidic substance and boric acid, and carrying out a chemical reaction to obtain the organic aluminum-zirconium-boron cross-linking agent. According to the invention, aluminum and boron are introduced into a traditional acidic zirconium cross-linking agent, and triethanolamine is introduced, so that the prepared organic aluminum-zirconium-boron cross-linking agent has excellent temperature resistance, and the temperature resistance is as high as 170 DEG C.

Description

technical field [0001] The invention relates to the technical field of crosslinking agents, in particular to an organoaluminum zirconium boron crosslinking agent, a preparation method thereof, and an acidic guar gum fracturing fluid. Background technique [0002] As the scope of fracturing operations in oil and gas fields continues to increase, more and more alkali-sensitive formations are encountered. Such formations are suitable for acidic fracturing fluid systems. There have been fracturing fluids of this type in the past. The acidic cross-linking agent has poor temperature resistance, and the highest temperature resistance can only reach 80°C. There is no report of an acidic cross-linking agent with a temperature resistance higher than 170°C. Contents of the invention [0003] In view of this, the object of the present invention is to provide an organoaluminum-zirconium-boron crosslinking agent, a preparation method thereof, and an acidic guar gum fracturing fluid. Th...
