Abstract

The invention discloses an instant clean fracturing fluid which consists of the following components in parts by weight: 2-6 parts of ethanolamine, 3-7 parts of erucic acid, 4-8 parts of an activator,5-9 parts of an organic salt, 7-11 parts of epoxy chloropropane, 3-5 parts of an alkali powder, 4-10 parts of an inorganic salt, 20-40 parts of ethanol and 30-50 parts of distilled water; The ethanolamine, the erucic acid, the activator, the organic salt, the epoxy chloropropane, the alkali powder, the inorganic salt and the ethanol are organically combined, the formula is reasonable, and the cost is low; after a series of operation of material preparation, primary reactions, crystallization, finished product preparation and packaging, the instant clean fracturing fluid with excellent qualitycan be prepared; the organic salt, the alkali substance and the inorganic salt comprise a great amount of hydrophilic substances, so that instant dissolution of the fracturing fluid into water is facilitated; and very good stability can be achieved, and the requirement of high temperature resistance can be met.

Description

technical field [0001] The invention belongs to the field of fracturing fluid technology, and more specifically relates to an instant and clean fracturing fluid. Background technique [0002] Fracturing fluid refers to a heterogeneous and unstable chemical system formed by various additives in a certain ratio. It is a working fluid used in fracturing oil and gas reservoirs. Its main function is to transmit the high pressure formed by ground equipment. into the formation, fractures the formation to form fractures and transports proppant along the fractures. [0003] The hydraulic fracturing process of the oil layer is to use a high-pressure and large-displacement pump on the ground, and use the principle of liquid pressure transmission to inject a liquid with a certain viscosity (usually called fracturing fluid) into the oil layer with a pressure greater than the absorption capacity of the oil layer. Injection, and gradually increase the pressure in the wellbore, so as to su...
