Description

technical field [0001] The invention belongs to the technical field of fracturing aids, and in particular relates to a multifunctional integrated gas well fracturing aid and its preparation method and application. Background technique [0002] Oil and gas reservoir stimulation is usually improved by fracturing to achieve the purpose of increasing production. For fracturing construction, fracturing fluid is the key to fracturing. At present, fracturing fluid systems include oil-based fracturing fluid system and water-based fracturing fluid system, of which water-based fracturing fluid system occupies a dominant position. For the gas well fracturing fluid system, since the water-based fracturing fluid used in the development process enters the reservoir, it will cause various damages to the reservoir, and the gas well reservoir generally has relatively dense pores, which will affect the increase in production and cause The reduction of economic benefit needs to prevent and pr...
